The climate in Cambodia is tropical and warm and humid and is divided into two main seasons: the dry season from November to March and the rainy season from April to October. Temperatures remain high all year round, so it is always warm. Within the dry season, however, the months of March to May can get very hot (often over 35°C, in April even up to 40°C), while December and January are among the "cooler" months with more pleasant 22-28°C. The rainy season is characterised by sometimes heavy, but often short showers, which usually occur in the afternoon or evening. The highest rainfall usually occurs in July, September and October.
