The Water Resources and Meteorology Ministry urged people travelling by water to take extra care amid heavy rain in the coastal provinces of Koh Kong, Preah Sihanouk, Kampot and Kep, with waves reaching 1.75 metres.
In an August 21 advisory, the ministry said a low-pressure system over the South China Sea was strongly influencing the southwest monsoon and Cambodia’s weather. Cloud and moderate to heavy rain with thunderstorms and gusts were expected across most of the country from August 21 to 31, 2025.
Moderate rain, thunderstorms and gusts could cover about 45% of the lowlands, including Banteay Meanchey, Battambang, Pursat, Kampong Chhnang, Siem Reap, Kampong Thom, Kampong Cham, Tboung Khmum, Prey Veng, Kandal, Takeo, Svay Rieng and Phnom Penh.
Moderate to heavy rain with thunderstorms and gusts could cover about 55% of the uplands, including Kampong Speu, Pailin, Oddar Meanchey, Preah Vihear, Kratie, Stung Treng, Ratanakiri, Mondulkiri and the Dangrek and Cardamom mountain areas.
Moderate to heavy rain with thunderstorms and gusts could affect about 60% of the coastal area, including Koh Kong, Preah Sihanouk, Kampot, Kep and the Bokor mountain area. Average wave heights were forecast to range from 0.50 to 1.75 metres.
The ministry urged the public, particularly people travelling by water, to be careful. It said it would continue monitoring and analysing conditions and issue updates if they changed.
