Cambodia in July: Weather, Crowds & What to Expect

Siem Reap & Northwest (Angkor, Battambang)

August stays within the monsoon rhythm: mornings may be bright but heavy showers and thunderstorms are common in the afternoon and evening. Visibility at Angkor can be variable - dramatic clouds can either lend atmosphere to photos or close out views, and insects are at their peak in wooded temple areas. Travel times to outlying countryside and to Battambang can be slower because of soggy rural roads.

Tonle Sap & Central Plains (Phnom Penh, Tonle Sap Lake, Kampong Thom)

July keeps the monsoon rhythm with frequent downpours, humid nights, and rivers high; the Tonle Sap’s floodplain is dramatic and offers superb wildlife viewing if you can handle damp conditions. Road travel between provinces may be slower because of saturated surfaces; local markets are lively under tarpaulins for shelter. Bring waterproof bags for electronics and choose flexible itineraries for excursions into rural areas.

Southern Coast & Islands (Sihanoukville, Koh Rong, Koh Rong Samloem, Kep)

July continues the monsoon pattern: persistent humidity, regular storms and unsteady sea conditions that can make boat transfers unpredictable. Island beaches are often empty except between squalls, and some remote trails in Ream National Park are slippery and overgrown. Bring sturdy sandals and expect flexible plans if you want to explore coastal mangroves and waterfalls.

Cardamom Mountains & Southwest (Koh Kong, Cardamom range, Bokor, Botum Sakor)

July continues the heavy-rain regime with saturated trails and high humidity; trekking requires solid gear and local guides who know safe routes. The coastline near Koh Kong sees rough seas and fewer tourist boats operate; check in advance for transfers. Bring quick-drying clothing and tarpaulins - camps and riverside lodges prepare for downpours and some facilities reduce operations.

Northeast Uplands (Ratanakiri, Mondulkiri - highlands, waterfalls, ethnic villages)

July keeps intense rainfall and high humidity across the highlands, with dramatic waterfall flows and saturated trails that may require detours. Wildlife is active and forest canopies are dense, but independent trekking becomes difficult and local guides are essential. Bring quick-drying clothing and plan indoor contingency activities like cultural village visits if heavy rain limits the trails.
