What you gain in May
- ↑Hotels drop 30–40% from peak season rates; even riverfront properties become genuinely affordable — a budget window for experiencing the city at its most Cambodian
- ↑The city operates almost entirely for locals — street food markets, tuk-tuks, and the Phsar Thmei (Central Market) are authentic rather than tourist-facing
- ↑Pchum Ben preparations begin, adding ceremony to temple visits — monks chanting at dawn adds an atmospheric layer absent in the dry season
What you sacrifice
- ↓155mm of rain — just over the hard threshold; heavy afternoon downpours are daily events; outdoor attractions including the Killing Fields require weatherproof preparation
- ↓Tuol Sleng Museum's outdoor courtyard areas and the Silver Pagoda become genuinely difficult to visit during downpours
- ↓Humidity at 78% makes the heat feel heavier than the thermometer suggests — 34°C with daily rain feels considerably more oppressive than dry-season heat
