According to CropWatch monitoring, during July–September 2025, rice production in Cambodia’s main growing areas experienced a slight decline. The planted area for rainy-season rice reached 3,276 thousand hectares, a 1.7% increase from 3,221 thousand hectares in 2024. However, high temperatures reduced the average yield from 3,167 kg/ha to 3,086 kg/ha, a 2.6% decrease. Consequently, total production slightly declined from 10.2 million tons in 2024 to 10.11 million tons, a 0.8% reduction.

Agro-climatic monitoring by CropWatch indicates that average rainfall during July–September 2025 was 750 mm, 38% below the 15-year average. The mean temperature was 26.5°C, 1.0°C above the 15-year norm, while RADPAR increased by 10% to 918 MJ/m². Reduced precipitation and higher temperatures led to a decrease in BIOMSS to 1,338 gDM/m², 10% below the 15-year average. The cropped arable land fraction (CALF) was 95%, slightly below the five-year average by 1%, and the VCIx was 0.91, indicating relatively favorable overall vegetation conditions. Regionally, the northern plains, northeastern areas, Tonle Sap region, and lower Mekong River basin experienced some stress due to lower rainfall and higher temperatures, affecting crop growth and yield.

In summary, during the 2025 rainy season, Cambodia faced challenges of insufficient rainfall and elevated temperatures, placing rice production under slight stress.
