What you gain in October
- ↑Bon Om Touk (Water Festival / Bon Om Touk) marks the miraculous reversal of the Tonlé Sap river flow: the spectacular boat races on the river in front of the Royal Palace draw hundreds of thousands of Cambodians — the single most electrifying event in the Cambodian calendar
- ↑Budget accommodation across the city remains extremely affordable — except for the 3-day Water Festival weekend itself when demand spikes sharply
- ↑Sunshine hours recover to 6 daily — more reliable morning windows for photography and outdoor visits than the July–September core monsoon
What you sacrifice
- ↓250mm is Phnom Penh's single wettest month — weather score capped at 2; flooding is a real risk in lower-lying districts and around the lake areas
- ↓Water Festival weekend drives hotel prices to their peak for the year — book months in advance or accept very limited availability; the city hosts over 2 million visitors for the festival
- ↓The combination of extreme crowds during the festival and heavy rain requires significant logistical planning; the 2010 stampede tragedy has made the city security-conscious during peak festival moments
