Climate Overview
Siem Reap experiences a tropical monsoon climate with two distinct seasons that heavily influence visitor experience and accommodation costs. Temperatures stay warm year-round, typically ranging from 24°C to 35°C (75°F to 95°F), but humidity and rainfall patterns create very different travel conditions. The region receives most of its annual precipitation between May and October, while November through April remains relatively dry.
Best Time to Visit
November to February offers the ideal window for exploring Siem Reap. During these months, cooler temperatures (around 25°C/77°F) and low humidity make temple visits at Angkor Archaeological Park genuinely comfortable, especially for early morning sunrise visits. Hotel rates during peak season (December-January) reflect this popularity, with mid-range hotels ranging from $40-80 per night, compared to $20-40 during shoulder months. If crowds concern you, visit in November or February when weather remains pleasant but visitor numbers drop noticeably.
Seasonal Breakdown
March to May brings intense heat exceeding 35°C (95°F), making outdoor sightseeing exhausting but accommodation significantly cheaper. The monsoon season (June-October) transforms the landscape into lush green but delivers daily afternoon downpours—temple exploration requires flexible planning, though fewer tourists mean better value. Consider visiting during early September or October when rains diminish; you'll experience manageable weather and discover quieter temple grounds at budget-friendly rates.
