All Months
November through March delivers the sweet spot — dry, sunny, and relatively cool. Temperatures hover around 75-85°F instead of the brutal 95°F+ you'll get in hot season. This is peak tourist time, so book accommodations early and expect crowds at major temples.
December and January see the biggest crowds and highest prices. But the weather stays perfect and you'll have clear skies for those sunrise temple shots everyone's chasing.
April and May turn brutal. Temperatures hit 100°F+ and humidity makes it feel even worse. Some travelers love the empty temples and rock-bottom hotel rates, but temple climbing becomes genuinely uncomfortable.
June through October brings monsoon rains. Not constant downpours — more like intense afternoon storms that clear quickly. The countryside turns lush green, waterfalls flow at their strongest, and you'll have temples mostly to yourself. Just pack rain gear and flexible plans.
Rainy season has one major upside: Tonle Sap Lake fills up and floating villages become accessible. Plus hotel rates drop by 50% or more.
