Best time to visit Phnom Penh

Cool dry season (peak season)
From November to February, temperatures are usually around 24–30°C (75–86°F) with lower humidity and clearer skies. This period is popular for sightseeing, walking between attractions, and enjoying riverside evenings in comfort, so you can expect a livelier, peak season feel.

Hot dry season (shoulder season)
March to early May brings hotter days, often 28–35°C (82–95°F), with strong sunshine and hazier afternoons. It is a good time for slower-paced city breaks, relaxing in shaded cafés, and planning indoor visits during the warmest hours while still enjoying long daylight.

Green rainy season (low season)
From May to October, short, intense showers usually arrive in the afternoon or evening, with temperatures around 26–32°C (79–90°F). The rain freshens the air and surrounding countryside, and you can enjoy quieter attractions and dramatic cloudscapes, making this an appealing low season for flexible travellers.
