Phnom Penh in September
Not the best time
September delivers the year's worst weather with devastating rains and flooding. The Pchum Ben festival provides cultural compensation, but most travelers should avoid this month entirely.
Weather
September typically sees peak rainfall with the most intense storms of the year. Flash flooding becomes a serious concern, especially in the late afternoon. Even brief walks outside leave you completely soaked.

All Months
November through March brings the sweet spot - dry weather and temperatures that won't melt you. Expect highs around 85°F instead of the brutal 95°F+ from April to October. December and January see the most tourists, so book accommodation early and expect higher prices. February and March offer the best balance: good weather, fewer crowds, and reasonable rates. The rainy season (May-October) isn't terrible if you don't mind afternoon downpours. Hotels drop prices by 30-40%, and the city looks greener. But some rural day trips become impossible due to flooded roads. April is hell - hot, humid, and dusty before the rains start. Locals call it the suicide month for good reason.
