Cambodia Weather & Seasons – Everything You Need to Know

Cambodia is a small tropical country surrounded by Thailand, Laos, and Vietnam. The weather can generally be described as hot, muggy, and dusty during the Hot Season. After what feels like an eternity, Rainy Season comes along and wets everything down prepping the country for the small drop in temperature of the Cool Season.

What you really need to know is that the weather and seasons in Cambodia allow you to perpetually wear a t-shirt and shorts. Sometimes you’ll need the added protection of a plastic rain jacket during flash storms but that’s about it.

Click below to jump to the season that interests you or read this whole piece to go on a deep dive into Cambodia’s weather, seasons, holidays, festivals, and celebrations. Of course, accompanied by some quick tips from our experienced tour guides!



Hot Season in Cambodia

Did you know temperatures in the hot season (March – June) can reach into the 40’s°C/104°F? During this time, Cambodia’s humidity levels also rise, eventually leading to the rainy season.

Fun Fact #1: The tropical humidity makes Cambodia feel much hotter than it actually is!

If you want to get the most out of your trip to Cambodia during the hot season, aka summer, which starts right after the cool season in March. Hot season will last until the beginning of rainy season in June.

This time of year is also known as the dry season.


During hot season, heat levels start rising accompanied by little to no rainfall. This leads to the water in lakes and rivers dropping to low levels which can make traveling by boat difficult or impossible.Despite the heat, this is a popular time for tourists to visit Cambodia. Actually, this is the second busiest time of year. Many attractions and activities will be crowded so it pays off to plan ahead.

Another tip we have for you adventurous travelers is to bring your swimsuit with you wherever you go. There are pools and lakes everywhere and are one of the best ways to cool off.

A common mistake many people make when traveling to Cambodia is wearing short clothes to beat the heat. Don’t do it! The sun feels unbearable during Cambodian summers and your skin will easily burn! It’s fine to wear less clothing during the cool season as the sun isn’t too strong.

If you want to protect your skin and not suffer the pains of being sunburnt, cover your body! Think loose pants, loose long-sleeves, hats, and sunscreen. You may find this weird but watch how the locals dress. They don’t want to burn to a crisp so they cover their bodies.

Are you wondering how to stay hydrated? Especially when you’re wearing all those clothes.

Coconuts cost $0.75 (3000 riels)
Luckily, you’ll find coconuts everywhere in Cambodia. These do an amazing job of keeping you healthy and hydrated. Drink plenty of water as well and sometimes add a Royal-D. Royal-D is a powdered electrolyte drink mix that you add to water.

The last tip to survive Cambodia’s hot season is to copy the locals. Paying attention to how locals act will help you figure out the best ways to beat the heat. Ever notice around 11 o’clock people start laying in hammocks or sitting in the shade. They usually stay in this state of relaxation until 1.


Because this is the hottest time of the day and is also when the sun hits the hardest. We already talked about how locals dress but there is one more thing to copy.

Take frequent cold showers. Many people shower 3 to 4 times a day during the hot season. Just a quick rinse with cold water and sit in the shade while drying off.

Hot Season Activities in Siem Reap

Despite the heat, summertime is busy in Cambodia. You can participate in most activities but you should expect a crowd. The few things you might have a problem doing will be involving water. This is because during hot season Cambodia’s lakes and rivers start drying up.

Move on to Rainy Season

Rainy Season in Cambodia

Cambodia’s rainy season, also known as wet season, is aptly named thanks to the heavy, frequent showers that soak the country. The season can start as early as the month of May (when the country is hot and dusty!) and can last up until November (when the rains stop and the country cools down).

At the start of Cambodia’s wet season, temperatures and humidity levels are still pretty high, which means that even though it rains, it still feels hot and sticky instead of cool and refreshing. It beats the hot and dusty weather of hot season though.

Siem Reap Shuttle
Rainy season is one of our favorite times of the year to explore, as the temperatures start to cool down eventually leading into cool season. The most enjoyable aspect of this time of year is that everything everywhere is green! Seriously!

Cruising in the countryside is amazing. Expect to see verdant rice paddies, lush tropical foliage, blossoming flowers, and overgrown jungles.

The heavy rains make this season a great time to travel by boat as lake levels rise and rivers can swell up to twice their size.

There are fewer tourists visiting the Kingdom during rainy season, which is why many businesses call this time of the year low season. For you, that translates to shorter wait times, no tourists in your Angkor Wat shots (maybe), and lower prices!

Ok, so what’s the downside? Why aren’t there that many visitors?

flood in cambodia during rainy season
With the rain, Cambodia’s unpaved, dirt roads turn into muddy slip n slides. The heavy rains often flood roads masking potholes, so be extremely careful when driving. The possibilities for floods, both in the cities and the countryside, are high during rainy season.

Most travelers come to the Kingdom of Wonder expecting sun, not rainfall which is another reason why there are fewer tourists.

Even though it will likely rain every day, that doesn’t mean you can’t go outside and explore. Downfalls generally occur during the afternoon so morning excursions can be good choices.

Don’t count on umbrellas keeping you dry as monsoons bring heavy winds to accompany the rain. Keep your clothes dry by investing in the cheap plastic ponchos available everywhere, usually for less than a dollar.

Pro Tip: Don’t wear socks and shoes when you’re out and about. When the rain stops and the sun comes back out, your feet will stay soaked. Prolonged wet feet can lead to all kinds of trouble. Wear flip-flops and sandals instead so your feet can dry easily.

Cool Season in Cambodia

Cambodian winters start in November and end in February. However, the word ‘winter’ probably doesn’t hold the same meaning for you as it does for Khmer people. There is no snow, no ice, and no frost. January, the coldest month of the year, has an average low temperature of 21°C or 70°F! This refreshing season comes right after rainy season and is one of the most popular times to travel through our beautiful country.


Temperatures are lower than any other time of year and when it does get hot there seems to always be a nice breeze rolling through the country. Don’t think that you’re the only traveler wanting to take advantage of this lovely weather. Unsurprisingly, November also marks the beginning of high season.

High season is when the majority of tourists travel to Cambodia. As a result, many hotels and restaurants are already fully booked, attractions are filled with large crowds, and if you don’t plan ahead you run the risk of experiencing a mediocre holiday.

Cool season can be a strange time. Both unexpected rains and overwhelming heatwaves can happen. That’s why we recommend you to keep both a rain jacket and a swimsuit on hand. Rain jackets can be found pretty much everywhere at a low price.

If you do find yourself feeling too hot, you don’t need to rush to your hotel room and blast the AC. Pay a few dollars and you can cool down and relax in the hundreds of pools throughout Siem Reap.

Cool Season Activities in Siem Reap

This time of year holds the coolest weather in Cambodia and the heavy rainfalls from rainy season have filled the rivers and lakes. These are some of the reasons that winter is a great time to visit Siem Reap attractions, even though it’s practically impossible to avoid the hordes of eager tourists this time of year.

If you’re headed to Angkor Wat, the most popular attraction, our tour guides recommend that you choose the short, sunrise tour ( Angkor Wat => Ta Phrom => Bayon) if you’re wanting to avoid the largest crowds.

Cool Season Festivals & Holidays

Cambodians love to party and it shows during our festivals. Unfortunately, there are only three major festivals during cool season; Bon Om Touk aka The Water FestivalInternational New Year, and the Chinese New Year.

Even two western holidays, Halloween and Christmas, are becoming increasingly celebrated in Cambodia.
