Satellite Imagery Captures Extensive Flooding Across Thailand

• Persistent heavy rainfall since late September 2026 has caused widespread flooding across 50 provinces in Thailand.
• The floods have impacted over 4 million people, caused dozens of deaths, and damaged 270,000 hectares of agricultural land.

Climate Factors

• A low-pressure system stalled over the region in late September, intensified by moisture and energy from the Gulf of Thailand.
• Bangkok received nearly 300 millimeters (11.8 inches) of rain over a 48-hour period, nearly meeting the typical monthly average for September.
• NASA-USGS Landsat satellite imagery compared conditions in Prachin Buri province between October 2025 and October 2026, showing significant inundation of land along the Bang Pakong River.

Impact and Assessment

• The International Federation of Red Cross and Red Crescent Societies reports that flooding has affected over 4 million individuals nationwide.
• Government agricultural estimates indicate that approximately 270,000 hectares (670,000 acres) of farmland—specifically rice fields and fruit orchards—have sustained damage.
