The year at a glance
Cambodia is hot and tropical with three seasons, and Siem Reap, the gateway to Angkor, anchors the ratings. The cool, dry months from November to February are the time to come, with comfortable days for exploring the temples and the lowest humidity.
March to May is the hot season, when temperatures soar, and the wet season from June to October brings short, heavy afternoon rains that green the countryside and fill the moats at Angkor. The southern coast around Sihanoukville follows a similar pattern.
