Local context
What to expect in November
🎯 Bon Om Touk (Water Festival) — boat races on Tonlé Sap. Spectacular Autumn in Siem Reap is often underrated: 31°C, golden light and declining crowds. An interesting window. Expect rain on 45% of days — a light raincoat in the bag is recommended. Not the best window, but acceptable if dates are constrained. January (8.3/10) is significantly better if possible.
