Siem Reap Climate - Seasons & Travel Advice
Siem Reap is characterized by two seasons. The dry season lasts for about half of a year from November to next April while the rainy season starts in May and ends in October.
Dry Season (November to April)
Siem Reap’s dry season from November to April is generally sunny and dry. The humidity is typically below 70%. There is a little rain and the monthly precipitation is generally below 55mm. With the relatively low humidity, rainless weather and moderate temperature, Siem Reap receives lots of tourists from all over the world, especially during the time from November to early March. April is one of the hottest months of the year, with the temperature ranging between 27-35℃ (81-95℉) and the highest temperature sometimes soaring to over 39℃(102℉); tourists also become thin on the ground since then.
Rainy Season (May to October)
Siem Reap has much rainfall in rainy season and the rainy days are as most as 15 to 22 days each month. With the monthly precipitation averaging between 180-260mm, the humidity during the period also increases a little, to over 70%. The temperature in the rainy season generally ranges between 25-32℃ (77-90℉). In the first two months of the rainy season, May and June have pretty high temperature of around 34℃ (93℉). Also because of the high humidity, the weather is hot and sultry. Accordingly, it is the low travel season and the good time to enjoy a leisurely Siem Reap trip. Thanks to fewer tourists, it is possible for you to capture the most fantastic pictures of the spectacular Angkor Wat complex.
