What you gain in September
- ↑The absolute lowest visitor numbers at Angkor: September is statistically the emptiest month across all temple zones
- ↑Budget prices at their maximum: the entire accommodation range from dormitory to boutique is at or near annual lows
- ↑For those willing to work around rain, solo access to Angkor's most atmospheric corners is unmatched at any other time of year
What you sacrifice
- ↓210mm of rain — the single wettest month: persistent and heavy downpours interrupt outdoor plans more severely than any other month
- ↓Some roads to outlying temples (Beng Mealea, Koh Ker) may be flooded or impassable in wet years; check current conditions locally
- ↓The least atmospheric and least comfortable month for Siem Reap's town life: Pub Street quiet, restaurants operating at reduced service, few other travellers to encounter
