What you gain in October
- ↑Bon Om Touk (Water Festival): occurring late October or early November depending on the lunar calendar — three days of boat races on the Tonle Sap River, the largest festival in Cambodia, drawing over a million people
- ↑Rain beginning its retreat: the second half of October brings noticeably longer dry windows and the first signs of the approaching dry season
- ↑Accommodation still at budget rates while the Water Festival delivers a genuinely unique cultural experience — the combination of low prices and major festival is the best-value event in the Siem Reap calendar
What you sacrifice
- ↓240mm of rain — October is the single wettest month, even wetter than September: the Water Festival celebrations happen in the rain, not under guaranteed sunshine
- ↓Water Festival week draws very large domestic crowds to Siem Reap and Phnom Penh; accommodation in both cities is difficult to find during the festival days
- ↓Angkor still receiving significant rain in early October: temple touring in the first two weeks involves mud, slippery stairs, and heavy afternoon downpours
