Siem Reap

Siem Reap is a prominent city in the Siem Reap region of Cambodia, with a sizeable population that drives demand for detailed weather data.

Typical of much of inland Southeast Asia, Siem Reap has a tropical savanna climate: hot temperatures throughout the year, a pronounced wet season from May to October, and a drier, sometimes hazy season from November to April. Weather forecasts here focus heavily on rainfall timing during the monsoon months.

During the rainy season, Siem Reap can see several centimetres of rain in a single afternoon. Storms often arrive late in the day and clear by evening, leaving humid but cooler conditions overnight.

Visitors looking for the best weather in Siem Reap should aim for the November–February window, when the monsoon has passed and humidity drops noticeably.

Siem Reap lies near sea level, so coastal breezes and ocean-moderated temperatures play an important role in day-to-day weather.
