Things to Do in Siem Reap When It Rains

The first time it properly rained on me in Siem Reap, I was standing on a temple terrace with a borrowed plastic poncho, watching a sheet of grey water march across the forest towards me like a curtain being drawn. Thirty seconds later every tour group on the terrace had vanished, and I had one of the most famous ruins on earth almost to myself. That is the thing nobody tells you about the wet season here. It is not a ruined holiday. It is a different holiday, and in a few ways a better one, as long as you plan it with a bit of sense.

So this is the guide I wish I had read before that trip. It is written for a Singapore traveller who has already seen the dry-season photographs of Angkor and is wondering what actually happens if you book flights in July, or September, or find the forecast turning on the very week you are there. I will tell you what the rain really does, which temples cope with it and which ones turn into mud, what to do when a downpour traps you in town for an afternoon, and what it all costs. I will also be honest about the days that simply go wrong, because they happen.

What the rainy season in Siem Reap is really like

Cambodia's wet season runs roughly from May to October. Anyone who has lived in Singapore will find the pattern familiar, with one big difference: here the rain is far more predictable. In the heart of the season, the morning is usually bright, the heat builds through lunch, clouds stack up in the early afternoon, and somewhere between about two and five o'clock the sky opens. It might pour for forty minutes. It might go on for three hours. Then it stops, the air smells of wet earth and frangipani, and the evening is often gorgeous.

The shoulder months, May and June, feel like a gentle warm-up, with short sharp showers and a lot of sun between them. July and August are steadier, greener and a little cooler. September and October are the wettest stretch, when you can get a full day of grey, and when the roads out to the more remote sites can turn to soup. By November the skies clear and the dry season, the high season, begins, with the prices and the crowds to match.

Temperatures hover around the high twenties to low thirties, and humidity is heavy, but after Singapore you will barely notice. What you will notice is the landscape. The rice fields around town go an almost fluorescent green, the moats around the temples fill to the brim, and the whole place looks like somebody turned up the saturation. Photographers who come in the dry season see dust and brown grass. You get colour.

Is it worth going in the rain at all?

I get asked this a lot, usually by friends who have been quoted a very attractive hotel rate and are now nervous. My honest answer is yes, with conditions. The conditions are that you accept you will get wet at least once, that you are flexible about the order of your days, and that you do not pack a ten-site temple marathon into three days and then sulk when the sky refuses to cooperate.

What you gain is real. Crowds at the headline temples thin out dramatically. Hotels and guesthouses drop their rates and are often happy to negotiate. Drivers and guides have time for you. The light, with clouds breaking up behind the towers, is more dramatic than the flat blue of the dry season. And the town itself feels like a place people live in rather than a place people pass through.

What you give up is certainty. A sunrise at the big temple, the single most photographed moment in the country, may simply be a grey smudge. If that one image is the entire reason you are travelling, the dry season is the safer bet. If you are curious, relaxed and happy with an afternoon of noodles while it buckets down outside, come in the rain. I have done both, and some of my favourite memories are from the soggy trips.

The temples: what works in the rain and what does not

Here is the part that matters most for planning. Not every temple behaves the same way when wet, and a little local logic goes a long way. The stone is the issue. Old sandstone and laterite become genuinely slippery, steps are steep and uneven, and many of the famous climbs have no handrails to speak of. The rule I follow: if there is a steep ascent, I do it in the dry window or I skip it.

Angkor Wat itself

The great temple is, perhaps surprisingly, one of the more rain-friendly sites, because so much of it is covered. The long galleries with their carved bas-reliefs have roofs, so a downpour simply gives you an excuse to slow down and read the walls. The battle scenes, the churning of the sea of milk and the processions of apsaras are all under cover. Do the galleries when it rains, and save the upper-level climb to the central towers for when it clears. Note that the top level has its own queueing system and dress rules, and wet steps make the queue move slower than usual.

If you want the classic temple day without the logistics, a guided option takes the stress out of timing. This Angkor Wat sunrise or sunset full-day tour is priced from S$19.21, and a guide who has watched hundreds of afternoons turn can usually tell you whether to stay put or move on.

Bayon and Angkor Thom

The walled city of Angkor Thom is where the huge stone faces smile down at you from the towers of the Bayon. In the rain these faces turn dark and glossy, and the whole place feels older and quieter. The terraces are mostly flat and the walkways are easy, so this is a good site for a drizzly morning. Moss shows up green against the grey stone. Bring a small dry bag for your phone, because the best angles are often the ones where you stop in the open to look up.

Ta Prohm and the jungle temples

The temple with the strangler figs growing through the walls is, to my mind, at its best in the wet. The forest canopy catches much of the rain, so you are often drier than you expect, and the roots look like they are drinking. Be careful on the loose, uneven paths between the piles of fallen stone. Go early, because when the tour buses arrive, even the wet-season version gets busy at the famous doorway.

Banteay Srei and the outer sites

The pink sandstone carvings at Banteay Srei are exquisite, and the wet makes the colour deepen. But the road out there, and especially to the farther temples like Beng Mealea or Koh Ker, can be rough in heavy rain. If you want the outer circle, go in a private car rather than a tuk-tuk, and have a backup plan. I would not book a remote site for the middle of September unless my driver told me the road was fine that week.

Phnom Bakheng and other hilltop climbs

The hill temple is the classic sunset spot, and in the rain it is a poor choice. The climb is steep, the steps are slick, and the view from the top is often a wall of cloud. Skip it on a wet day. The same goes for Phnom Kulen, the sacred mountain north of town, where the waterfalls look dramatic after rain but the trails and roads are tougher going.

The Angkor pass and how rain changes your plan

You need a pass to enter the temple park, and it is sold as a one-day, three-day or seven-day ticket. Check the current prices on the official ticket site before you travel, as they have changed in recent years. The three-day option is valid across a longer window than three consecutive days, which is a gift in the wet season, because it lets you spread your visits around the weather rather than forcing them into a fixed block. I would always lean towards a multi-day pass in the rainy months for exactly this reason.

The ticket line in the morning can be slow, particularly at peak times. If you do not fancy standing around, there is an express service for the Angkor temple pass, from S$57.15, that handles the queue for you. Rain makes queues feel much longer than they are, so for me this is one of those small conveniences that pay for themselves.

A tactic that worked well for me: a dawn start, three hours in the temples while the sky is still behaving, back to the hotel for a long lunch and a nap through the worst of the afternoon, and then, if the weather has cleared, out again for the last hour of light. You will see more, get less wet and stay sane.

Rain-day activities in town

Every wet-season traveller needs a short list for the afternoon the weather wins. Here is mine, built from several soggy trips. None of it is filler. Some of the best hours I have spent in Cambodia were on days I had written off.

Learn to cook Khmer food

A cooking class is the classic answer to rain, and for good reason. You start with a market visit, if the weather lets you, then move into a covered kitchen to pound, chop and steam your way through a few dishes, and finally sit down to eat what you made. Fish amok, the steamed curry in banana leaf, is the signature. Green mango salad and beef lok lak are other regulars.

There are several to choose from. The cooking class at Shinta Mani, from S$76.42, pairs a morning market walk with a hotel kitchen. The Changkran Khmer Restaurant class, from S$57.12, takes place in a traditional wooden house with a chef who clearly loves teaching. And if you would rather leave the town behind, the village life and farm-to-table cooking experience, from S$81.20, takes you out to a rural setting for crafts and cooking together.

Go to the circus (properly)

The Phare Cambodian Circus is not a circus in the sawdust-and-animals sense. It is a performance by graduates of a local arts school, mixing acrobatics, music, dance and theatre to tell very human stories. It happens under a big tent, so rain does not matter, and the hour-long show is genuinely moving. Book the dinner package if you want a table and a starter beforehand. The Phare Circus dinner for families from S$83.13 is the one I would pick if kids are along, since it comes with a children's menu and some interactive games.

Visit the aquarium

It sounds odd to suggest an aquarium when it is already wet outside, but the Angkor Wildlife and Aquarium is a proper indoor attraction, with large tanks and a spread of regional animals. It is the sort of place you take children when the afternoon has gone grey and you need ninety minutes of dry entertainment. The Angkor Wildlife and Aquarium ticket starts from S$25.55, which makes it one of the cheapest rain-day options.

Book a massage or a spa afternoon

After a morning of climbing temple steps, a massage is not an indulgence, it is maintenance. Siem Reap has a wide range of spas, from simple foot places to proper wellness retreats. Bodia Spa uses locally sourced natural ingredients, and its aromatherapy massage is available from S$47.68. Listening to rain on the roof through a massage is, quite honestly, close to perfect.

Eat your way through town

Food tours are underrated for bad weather. You move between restaurants by tuk-tuk with a canopy, and each stop gives you shelter and a plate of something good. The Khmer Discovery Food Tour is a progressive dinner across three well-regarded kitchens, from S$96.00. It runs in the evening, which is often when the rain has eased.

Afternoon tea in a colonial dining room

A slow afternoon with pots of tea and small cakes is a decent way to wait out a thunderstorm. A few of the well-known hotels, including the FCC Angkor Avina, run proper afternoon tea setups. I will not pretend it is a cultural experience, but it is lovely, and the sound of a storm over a garden pool is lovely too.

Galleries, markets and workshops

The town has a handful of small art galleries, silk workshops and craft stalls where you can watch artisans at work. The covered night markets keep running in the rain, though the lanes get puddly and you will be wiser in closed shoes. Most workshops are indoors and welcome walk-ins. Bargain gently, with a smile, and remember that a dollar means a lot more to the seller than it does to you.

Tonle Sap and the floating villages in the wet season

This is where the wet season really shows off. Tonle Sap is the largest freshwater lake in Southeast Asia, and its size swells enormously as the monsoon rains arrive and the river system backs up. The floating villages near Siem Reap, built on stilts or on boats, suddenly sit on a much larger body of water, and the boat rides are longer and more atmospheric. The water turns a milky brown, the horizon vanishes, and you can feel how entire communities live around a lake that breathes in and out through the year.

Be realistic about weather. A boat ride in a storm is not fun, and choppy water can cancel sailings. Go in the morning when the sky is generally calmer. Half-day tours generally bundle in a village visit, a floating school or market, and sometimes a meal. The Tonle Sap half-day tour with hi-tea starts from S$93.88, and there is a version with a buffet dinner and dance show, the half-day tour with buffet dinner, from S$81.53.

One thing I feel strongly about: treat these villages with care. They are homes, not theatre sets. Ask before you photograph people, and do not hand out sweets or cash to children. A guide who knows the community will steer you right.

Cycling, countryside and getting muddy on purpose

If you are the sort who does not mind a soaking, a bike ride through the villages is a joy in the green season. The tracks are quiet, the paddies are brilliant and farmers wave. A guided option like the full-day 30km Angkor cycling tour with lunch, from S$76.43, takes you along hidden trails between temples. It is not for everyone on a stormy day, so check the forecast the night before, and agree with your guide on a fallback if the sky turns ugly.

Quad biking and horse riding are also offered, and the countryside looks more dramatic in the green season, but mud is real. Wear clothes you are happy to throw away, and be honest with yourself about how much you enjoy being filthy.

Sample itineraries for a wet-season stay

These are loose templates, not rigid schedules. The point is the shape: outdoor early, flexible middle, indoor or evening activity late. Swap days around as the forecast demands.

Three days, the sensible version

Day one. Arrive, drop bags, wander the old market area and eat a long, slow dinner. Keep it light, because you want sleep before a dawn start. If you have flown in the same morning, the airport transfer is worth sorting out beforehand, since taxis and tuk-tuks can be hard to find in a downpour.

Day two. Up before dawn for the main temple and its galleries. Bayon and the walled city by mid-morning. Back for lunch and rest. If the sky clears, go out late; if not, book a spa and an early night.

Day three. Ta Prohm early while it is quiet, then a cooking class in the afternoon. Finish with the circus in the evening. It is a good rhythm and one that works no matter what the sky does.

Four to five days, adding the outer ring

With more time, add one day for the lake and floating villages, and one for the outer temples by private car, if the roads are open. A long weekend in town becomes a proper trip, and you can shuffle days around so that the best weather meets the sites that matter most. A private full-day option such as the private Angkor day tour with a circus ticket, from S$78.19, takes away the planning. For a classic group day with hi-tea at the end, there is also the Angkor full-day tour with hi-tea, from S$83.00.

What to pack, and what to leave at home

Packing for the wet season is about being sensible rather than stocked up. The checklist below has served me well, and nothing on it is expensive.

• A light rain jacket or poncho. A thin poncho is more useful than an umbrella on crowded temple steps. You can buy ponchos cheaply on the spot, but they tear, so bring a proper one.
• Quick-dry clothing. Cotton stays wet for hours. Light synthetics and linen dry quickly. Remember that temples ask for covered shoulders and knees, so lightweight long trousers and a loose shirt are your friends.
• Shoes with grip. Closed, gripping sandals or trainers. Flip-flops on wet stone are a recipe for a fall.
• A dry bag. For your phone, passport and wallet. Zip-lock bags in a pinch.
• Insect repellent. Mosquitoes love standing water.
• A spare pair of socks. A small luxury that makes a big difference.
• A power bank and a data plan. Maps, rides and translations all run on your phone, so a data eSIM sorted before you land saves a lot of faff.
• Sunscreen. Yes, really. The sun is strong between showers.

Visas, entry and getting the paperwork sorted

Entry rules depend on your passport, and they change, so please check your own situation rather than relying on a blog. As a general picture, Cambodia offers a tourist visa, issued as an e-visa online or on arrival at major airports and eligible land borders, for about USD 30 and a stay of up to 30 days, valid for entry within three months of issue. Some nationalities, such as Singapore and other ASEAN citizens, do not need one. Many Indian passport holders and others do.

The simplest way to confirm what you need is our visa requirements checker, where you choose your passport and destination and see the current entry rules. If you are applying for a visa to somewhere else on your wider trip and the embassy wants proof of onward travel, our flight reservation service provides a reservation to attach to a visa application. It is a reservation for paperwork, not an issued ticket, so do not treat it as a booked flight.

What it costs, honestly

Siem Reap is a good-value place. The wet season is cheaper still, though not by a dramatic amount on activities. Where you save is accommodation. Hotels commonly trim their rates, and some throw in extras. Think of the numbers below as rough guides, not promises, because they move with the season and the exchange rate.

Cash matters here. US dollars are widely used alongside the Cambodian riel, and small change in dollars is easiest. Cards work in hotels and bigger restaurants, but market stalls and tuk-tuks want cash. Keep small notes in a dry pouch.

Safety, health and small practicalities

Siem Reap is a relaxed place and the wet season does not change that, but a few habits help. Keep valuables dry and out of sight. Drink bottled or filtered water. Watch the tuk-tuk drivers when roads flood, since some streets can hold surprisingly deep water for an hour or so. Mosquitoes carry dengue, so repellent is not optional. Buy travel insurance that covers medical care, and keep emergency numbers saved in your phone before you go.

Thunderstorms can be violent. If you hear thunder at a hilltop temple or open terrace, get down and indoors. Wet stone, tall structures and lightning do not mix. Give the sky an hour and it will almost always pass.

Temple etiquette applies in all weather: cover shoulders and knees, take hats off inside sanctuaries, never touch carvings, and do not climb on structures that are roped off. Monks should not be touched, and women should not hand things directly to them. A quiet word and a smile cover most situations.

Getting around when the streets are wet

Transport is where the rain bites hardest, so it deserves its own thought. Tuk-tuks are the default way to move, and most have a canopy and side curtains that drop down when it pours. They are fun, cheap and slow, and you will still get splashed. For a full temple day, many people prefer a car with a driver, which keeps the bags dry and the air conditioning on. A private car also lets the driver wait out a storm with you rather than abandoning you at a gate.

Agree the price and the route before you set off, and ask the driver what he thinks of the weather. Locals read the sky far better than any app. If he says wait twenty minutes, wait twenty minutes. On the day you arrive or leave, a pre-arranged private airport transfer, from S$33.61, means no hunting for a ride on a dark, flooded kerb. Many hotels will also send a car if you ask politely in advance.

Walking around the old town is perfectly pleasant between showers, as the main streets are paved and well lit. Just watch for open drains, scooters that do not stop for puddles, and the odd stretch of pavement that vanishes under water. Keep your bag zipped, hold your phone in a dry pouch, and give yourself extra time. Nothing here is urgent, and the town rewards people who stroll.

Mistakes I made so you do not have to

I booked sunrise at the big temple on my first wet-season trip and treated it as a must-do regardless of the forecast. It was a grey, crowded, slightly miserable morning, and I was too stubborn to change plans. The next day I went to the same place at nine, in light rain, and had the galleries almost to myself. Be flexible.

I also wore the wrong shoes. Thin canvas sneakers soaked through on the first hour and stayed wet for two days. Proper grip, quick-dry materials, and a spare pair of socks would have saved me. And I over-scheduled, trying to squeeze six sites into one day with no buffer. A rain delay turned the whole plan into a scramble. Do fewer things, and do them well.

One more: I forgot to sort mobile data before landing and spent my first evening hunting for a shop. These days I arrange an eSIM before I leave, and it takes about five minutes.

Frequently asked questions

Is Siem Reap worth visiting in the rainy season?

Yes, if you are flexible. You get fewer crowds, lush scenery and lower accommodation rates, in exchange for a chance of a grey sunrise or a rained-off afternoon. Plan outdoor activities for the morning and keep indoor options ready for later.

Which months are the wettest?

September and October are usually the wettest, with July and August steadier and May and June lighter. Rain is usually concentrated in the afternoon, though you can get the odd full day of grey.

Can I still see Angkor Wat if it rains?

Absolutely. The covered galleries at the main temple, and sites like Bayon and Ta Prohm, work well in the wet. Save the steep upper-level climbs for dry windows, since the stone is slippery.

What should I wear to the temples in the rain?

Light, quick-dry clothing that covers your shoulders and knees, grippy closed shoes, and a poncho rather than a big umbrella. Pack a spare pair of socks and a dry bag for your phone and passport.

What can I do indoors when it pours?

Cooking classes, the Phare circus, the aquarium, spas and massages, food tours, galleries, craft workshops and covered markets are all good options. Keep one or two booked ahead for your most weather-sensitive days.

Is it safe to travel there during the monsoon?

Generally yes. The main risks are slippery stone, flooded streets, mosquitoes and thunderstorms. Take sensible precautions, stay off exposed hilltops during lightning, and follow local advice if roads are closed.

Do I need a visa for Cambodia?

It depends on your passport. Many travellers can get a tourist visa online or on arrival for about USD 30 and a stay of up to 30 days, while Singapore and other ASEAN citizens are generally exempt. Use our visa requirements checker to confirm the current rules for your passport.

Will booking tours in advance help in bad weather?

It helps with planning, because you can slot activities around the forecast. Check each listing's conditions for rescheduling and refunds before you pay, as rules differ by product.

Final thoughts from someone who got wet

If you take one thing from all this, let it be flexibility. Siem Reap in the rain rewards people who loosen their grip on the schedule. Go early, rest in the middle, and have a good plan B ready: a cooking class, a circus show, a long massage, a slow dinner. The temples will still be there, quieter and greener than the postcards promise, and the people will be just as warm, perhaps warmer, because you have given them time.

Sort your visa first with the requirements checker, pack a poncho, and book one or two experiences ahead so you are never stuck. Then let the afternoon clouds do what they do. I will bet that, like me, you come home with a few of your favourite photographs taken in the rain.
