Phnom Penh Weather Overview

Phnom Penh Weather

Cambodia has one of Asia’s simplest weather systems. Cambodia has two different weather seasons, yet it is possible to visit throughout the year. In general, the whole nation experiences similar weather patterns, owing to Cambodia’s relatively consistent height and latitude.

There are two different seasons: rainy (May to late September) and dry (October to late April). There are temperature differences within each season; the last few dry months before the rainy season (March and April) and the first few wet months (May and June) are often the warmest of the year, with occasional highs of above 35°C.

The months of October through December are often the coldest of the year, however, even these months are mild for Cambodia, with average highs of 24 to 26 degrees Celsius. Humidity peaks in March and April.

October – April/Early May

The dry season in Phnom Penh weather runs from October to April, during which time the nation is blanketed in scorching winds with the arrival of the dry northeast monsoon. While temperatures in the mid-20s are very mild in November through January, by April the heat is unbearable, so many people choose to see Angkor Wat early in the morning or late in the afternoon, and spend a few hours by the hotel pool over lunch.

It should come as no surprise that this is the busiest travel season in Cambodia due to the warm weather. 

The best roads and shortest travel durations are found in more isolated areas, including the northeastern Mondulkiri and Ratanakiri regions. The south coast towns of Kep and Sihanoukville are well-liked during this time of year because of the excellent weather and beautiful sunshine.

Early/Mid May – October

Almost 75% of Cambodia’s yearly rainfall occurs during the rainy season, which runs from May to October and is brought on by the southwest monsoon. Daytime highs in Cambodia throughout the majority of the rainy season typically range from 25 to 27 degrees Celsius. May through July, the first several months of the rainy season, are still extremely hot and dry with sporadic brief downpours of rain. The rain tends to become more consistent and heavy at times in the latter months (late July to September), especially in rural and coastal areas.

The condition of the roads makes it nearly difficult to go to the more isolated regions of the nation, such as Mondulkiri and Ratanakiri, and trips into the northeast are not advised during the wettest part of the year. The high waves also make access to Bamboo Island, which is near Kep, extremely restricted.
