Best Time To Visit Siem Reap By Season

Siem Reap has warm temperatures year-round, but the experience can feel very different depending on the season. The dry season brings the most comfortable weather for visiting temples, while the rainy season offers greener landscapes and fewer tourists.

Here’s what to expect throughout the year.

Cool and Dry Season in Siem Reap (November to February)

The cool season is generally considered the best time to visit Siem Reap. Temperatures usually range from around 70°F to 88°F (21°C to 31°C), with lower humidity and much less rain compared to the rest of the year.

This is the most comfortable season for exploring Angkor Wat and other temples around the city, especially if you plan to spend long hours outside.

Because the weather is at its best, this is also peak tourist season. Hotels, tours, and sunrise visits to Angkor Wat can get very busy, especially around December and January.

Pros:

  • Most comfortable weather
  • Lower humidity
  • Great conditions for temple visits
  • Minimal rainfall

Cons:

  • Largest crowds
  • Higher hotel prices
  • Busy sunrise tours at Angkor Wat

Best for:

  • First-time visitors
  • Temple sightseeing
  • Outdoor activities
  • Comfortable travel conditions

Hot Season in Siem Reap (March to May)

The hot season is the most intense time of year in Siem Reap. Temperatures often climb above 95°F (35°C), especially during April and May, and the humidity can make afternoons feel exhausting.

Temple visits during the middle of the day can become uncomfortable quickly, so early morning sightseeing is highly recommended.

However, this season also brings smaller crowds compared to peak tourist months.

Pros:

  • Fewer tourists
  • Lower hotel prices
  • Quieter temple visits

Cons:

  • Extreme heat and humidity
  • Difficult midday sightseeing
  • High sun exposure

Best for:

  • Budget travelers
  • Travelers comfortable with heat
  • Shorter temple visits

Rainy Season in Siem Reap (June to October)

The rainy season brings frequent afternoon showers, greener landscapes, and lower tourist numbers. Temperatures usually stay warm, ranging from around 75°F to 92°F (24°C to 33°C).

Rain showers are often heavy but short, meaning you can still explore temples and markets throughout much of the day. The countryside and temple grounds also become much greener during this time of year.

This season is often underrated because the rain helps cool temperatures slightly and creates a more relaxed atmosphere around Siem Reap.

Pros:

  • Fewer tourists
  • Lower accommodation prices
  • Lush green scenery
  • Cooler afternoons after rain

Cons:

  • Heavy rain showers
  • Muddy paths around some temple areas
  • More humid conditions

Best for:

  • Budget travel
  • Photography
  • Fewer crowds
  • Green season scenery

Best Time to Visit Angkor Wat

The best time to visit Angkor Wat is during the cool and dry season from November through February, when temperatures and humidity are much more manageable for long days of sightseeing.

Since most temple visits involve a lot of walking outdoors with limited shade, the weather can have a huge impact on your experience. The cooler months make it much easier to explore larger temple complexes like Angkor Wat, Bayon, and Ta Prohm comfortably.

If possible, try to visit the temples early in the morning. Sunrise tours are especially popular at Angkor Wat, but starting early also helps you avoid the worst afternoon heat.

The rainy season can also be a surprisingly good time to visit Angkor Wat if you do not mind occasional showers. The temple grounds become much greener, crowds are smaller, and photos can look especially dramatic after rainfall.

April and May are usually the most difficult months for temple sightseeing because of the extreme heat and humidity. If you visit during this time, plan for frequent breaks, carry plenty of water, and avoid long midday temple tours.
