Cambodia has a tropical climate with warm temperatures throughout the year.
There are two seasons in Cambodia. The northeast monsoon season runs from December through April, bringing sunny, dry weather especially in January and February. The rains come when the winds shift into the southwest monsoon from May to November, with the most precipitation in the months of September and October. But also the nicest colors in the skies.
Cambodia heats up steadily from February to April, with temperatures peaking as high as 40°C in April. Temperatures remain high in May and June, and the southwest monsoon brings in more humidity and some very sticky days! From July through October there will certainly be some rainfall but it usually comes in short showers.
