Siem Reap Weather Overview
Cambodia has two main seasons:
- Dry Season (November–April): Hot, sunny, and dusty. Perfect for sightseeing, but can be very hot by March/April. Many travelers choose high-SPF sunscreen sprays like this one for extra protection against strong UV rays when spending lots of time outdoors.
- Rainy Season (May–October): Warm, humid, and greener. Expect afternoon showers and occasional downpours—mornings are usually clear. Because the weather can sometimes change quickly while sightseeing, packing a compact travel umbrella like this one is always a good idea.
Average Temperatures:
- Highs: 86–100°F (30–38°C)
- Lows: 72–78°F (22–26°C)
Humidity is almost always high, especially during the wet months.
Month-by-Month Snapshot
- November–February: Cooler and dry. Best time to visit for weather. Bring light layers for early temple mornings. Many travelers stay warm with a quilted women’s jacket like this one that is the perfect travel layer for chilly mornings.
- March–May: Very hot and dry. Stay hydrated and plan sightseeing early in the day. To stay hydrated during long sightseeing days is important, so many travelers carry a collapsible water bottle like this one that folds flat when it’s empty.
- June–August: Green season begins. Showers often in late afternoon. Still good for travel.
- September–October: Rainiest months. Fewer crowds, lush scenery, and great for photography if you don’t mind getting a bit wet.
