Thailand Flooded by Persistent Monsoon Rains

Satellite imagery reveals widespread flooding in Thailand during late September and early October 2026, a period of intense monsoon rainfall.

Low-lying areas across Thailand experienced sustained flooding due to persistent heavy rains and intense downpours. Prachin Buri province was particularly affected, with areas along the Bang Pakong River, including agricultural and aquaculture facilities, inundated on October 2, 2026. False-color satellite images from NASA-USGS Landsat satellites, comparing 2026 to 2025, highlight the extent of the water.

The flooding is attributed to a stalled low-pressure system over the region in late September, fueled by moisture from the warm Gulf of Thailand. Bangkok received nearly 300 millimeters of rain in 48 hours, close to its average monthly rainfall for September.

The widespread flooding has impacted 50 provinces, affecting over 4 million people and causing dozens of deaths. Approximately 270,000 hectares of farmland, including rice fields and fruit orchards, have been damaged.
