Cambodia's temperatures stay pretty constant all year round with a distinct wet (monsoon season) and dry season (best time to travel). The north generally experiences slightly colder winters (dry seasons) than the south. The dry season is the most popular season to travel by far, as showers usually only occur in the late afternoon and for a matter of minutes before passing over. In the wet season, however, rainfall can be constant and heavy, with August and September bringing most of the monsoon rains to the whole country. That shouldn't put you off, though – the Angkor temples and terraced rice fields arguably look the best after a shower and without the smoky haze of the dry season. Plus, it's generally much quieter in the wet season.
Weather in Siem Reap
Siem Reap features a tropical wet to dry climate. It doesn't really drop much below 30°C (88°F) on any given day, but rainfall fluctuates dramatically between the wet season (May–October) and the dry season. Late November through February is usually an ideal time to visit Siem Reap – warm but pleasant days, cooler nights and not too much rainfall. Temperatures start to sneak up around February and short but sharp rain showers in the early evenings begin to become more frequent.

Weather in Kampot
Weather on the coastline is not much different from the tropical wet and dry season pattern in other regions in Cambodia. Expect temperatures to be slightly cooler at night, thanks to Kampot's proximity to the sea. Rainfall and humidity are a little higher than in the interior of the country, with humidity rising to around 90% during the wet season. Kampot's wettest period is from May to October, and the highest average rainfall is in August, with around 410 mm falling in a month.

Weather in Phnom Penh
Just like Siem Reap, Cambodia's capital is classified as having a tropical wet and dry climate. Temperatures don't vary greatly, but the city is subject to tropical monsoons in the wet season. The heaviest rainfall happens over September and October, and the driest month is February. Air temperature remains relatively constant throughout the year, with the highest average humidity in the wetter months.

Weather in Battambang
Battambang follows the trend of the major cities of Phnom Penh and Siem Reap: hot and wet in the monsoon season and slightly cooler and drier between December and February. The city sits on the river Sangker, which feeds into the Tonle Sap and Mekong rivers, and flooding can occur when these waterways swell during the wet season. Most of the rain falls in September – on average around 260 mm over the month.
