Cambodia Weather

Published On: March 28, 2025

Cambodia can be visited at any time of year, because even during the rainy season the weather in Siem Reap and other parts of Cambodia is never so bad that it makes it impossible to visit. Whatever the weather in Siem Reap is like, you could always take a tour around the Angkor temples.

Cambodia and Laos have a two-season weather pattern. Set between 13 and 17 north of the equator, the region has a warm tropical climate perfect for those seeking a change from the temperate European or North American climate.

The weather patterns are influenced by the wet and dry seasonal winds of Southeast Asia, which create two distinct seasons – dry and wet (also known as Green Season because of the vibrant color the rains bring).

When planning to travel in the region, it´s a good idea to consider three weather related factors:
-For tranquil, crowd-free travel and great hotel deals, travel outside of the peak, dry season months of November to March.
-Consider your tolerance of temperatures and humidity – often high by Western standards.

Our Senior Tour guide Advisors live in the region, (most for many years!) and so are well acquainted with the weather patterns and will be happy to give frank advice based on your travel dates.

  • The Region’s Two Seasons

Dry Season ( November – April ): Cool dry air from the North ushers in the Southeast Asian dry season; from the beginning of November until mid April, you can be sure of clear skies and almost no rain. The countryside dries out under the cloudless skies and the level of Tonle Sap lake drops to its minimum. The temperatures between November and February make up the traditional high season, as larger numbers of visitors travel through the region, coaxed by the promise of cloudless skies and cool temperatures. In April, the average humidity and heat rise to the highest of the year.

Green Season ( May – October ): May and June bring moisture-laden air from the Indian Ocean and the Gulf of Thailand, bringing greenery back to the region´s countryside. Don´t be concerned by the season´s showers, however; the rains form a predictable pattern – clear, sunny mornings and a 60% chance of showers in the mid to late afternoon-and bring green into the countryside. The humidity and temperatures drop to a low around October when the weather can feel almost Mediterranean.
