Floods still affect 2.46 million people in 20 provinces and Bangkok as of October 12
Thailand’s October 12 flood update reports 908,595 affected households, with water levels rising in Phitsanulok and Phetchaburi.
- As of October 12, ongoing floods in Thailand have affected nearly 2.46 million people and over 908,000 households across 20 provinces and the capital, Bangkok.
- The flooding is attributed to a combination of persistent heavy rainfall and significant runoff from northern regions flowing into central river basins.
- While water levels are falling or stable in many affected areas, they are still rising in the provinces of Phitsanulok and Phetchaburi.
- The Department of Disaster Prevention and Mitigation (DDPM) is actively providing emergency assistance, deploying drainage equipment, and preparing for recovery efforts and financial aid.
Flooding continues to affect 2,458,895 people in 20 provinces and Bangkok, Thailand’s Department of Disaster Prevention and Mitigation (DDPM) reported on Monday (October 12, 2026). Water levels are still rising in Phitsanulok and Phetchaburi.
The DDPM’s disaster relief command centre recorded 908,595 affected households in its 6am update on October 12, with standing water and overflowing rivers affecting 100 districts, 804 subdistricts and 5,947 villages.
DDPM Director-General Nirat Pongsitthaworn attributed the flooding to persistent heavy to very heavy rainfall, combined with runoff from northern Thailand entering river basins in the Central Region. Rising levels in major rivers and tributaries have inundated homes and extensive areas of farmland.
The DDPM, under the Ministry of Interior, is mobilising personnel, machinery and relief supplies to help affected communities, while preparing recovery work in areas where flooding is easing.
