Phnom Penh weather in June is dominated by the monsoon: expect warm temperatures, frequent rain and very high humidity. Travelers planning a visit in June should be prepared for heavy showers, limited dry spells and conditions that favour indoor activities or flexible itineraries.
Phnom Penh weather in June: background and overview
June falls squarely within Phnom Penh's wet season. Average air temperatures sit close to 29–30C, with daily lows usually near 26C and daytime peaks around 33C. Rain is common and can arrive in short, intense bursts or longer periods of steady fall.
Humidity during June is notably high, often reaching around 90% on humid days. The city records substantial monthly precipitation in June, which contributes to saturated streets and lush vegetation across parks and riverbanks. Because rainfall is frequent, outdoor sightseeing can be interrupted, but many historic and cultural sites remain accessible on drier intervals.
Key weather features and practical implications
June's climate in Phnom Penh combines warmth with the high likelihood of rain. Official summaries for the month typically cite an average temperature near 29C, a typical range between 26C and 33C, and total monthly precipitation in the region of 170mm.
Rainy days are common: many summaries indicate rain on most days of the month, which means planning for wet conditions is essential. The combination of heat and humidity can make walking and outdoor activities more taxing than during the dry months, and wet surfaces can slow travel between attractions.
- Average temperature: ~29C
- Typical daily range: 26CC to 33C
- Monthly rainfall: roughly 170mm (varies year to year)
- Humidity: frequently close to 90%
- Rainy days: many days with showers or thunderstorms
Practical tips for visiting Phnom Penh in June
Packing light, quick-drying clothes and a compact umbrella or rain jacket will make moving around the city easier. Choose breathable fabrics and bring footwear that dries quickly; avoid heavy cottons that stay wet for long periods. Many visitors also carry a small waterproof bag for electronics and travel documents.
Transportation during rainy periods can be slower. For safety and convenience, visitors often prefer public transport options or local drivers to renting and driving their own vehicle in heavy rain. If you do hire a vehicle, check tyres and brakes and allow extra time for journeys when roads are wet.
- Bring lightweight, quick-dry clothing and a small umbrella.
- Pack waterproof pouches for phones and documents.
- Plan flexibility into daily schedules—expect sudden showers.
- Consider public transport or local drivers rather than self-driving.

Cultural context and seasonal advantages
The rainy season influences local rhythms. Markets, temples and city life continue throughout June, but activities that depend on dry ground—open-air performances or long riverbank walks—may be cut short by downpours. Museums, galleries and indoor cultural centres remain good options on wet days.
Lower visitor numbers during the wet months often lead to quieter streets and more relaxed service at restaurants and hotels. Many guides and smaller attractions run reduced crowds, which some travellers appreciate when they prioritise a slower pace and more focused time at museums or historical sites.
- Indoor cultural sites offer reliable options during rain.
- Fewer tourists can mean more attentive service.
- Vegetation is greener—good for photography between showers.
If you are combining a Phnom Penh stay with other Cambodian highlights, a short overland trip to Angkor-area attractions is common. For planning temple visits and short itineraries, consult a compact Siem Reap itinerary to see how wet-season travel might affect temple touring.
Who benefits from visiting Phnom Penh in June?
June can suit travellers who prioritise lower prices, smaller crowds and flexible schedules. Visitors focused on indoor experiences—museums, cooking classes, restaurants and cafés—can have a full and rewarding trip despite rain. Photographers who like the contrast of saturated colours after showers may also find June appealing.
Conversely, anyone planning extensive outdoor treks, long river cruises or full-day cycling around town should be prepared for disruptions and possible cancellations. Families with young children may prefer to plan shorter outdoor windows or focus on covered attractions.
- Good for budget-conscious travellers and indoor-focused trips.
- Less suitable for extensive outdoor adventures or long bicycle tours.
- Ideal for travellers who can be flexible with timing and routes.
