Bangkok, Thailand - September 28, 2026: Thailand has declared a two-day special holiday for government and civil-service offices in Bangkok and three surrounding provinces as severe rainfall and widespread flooding continue to disrupt travel, communities and public services across the Bangkok metropolitan region.
The Thai Cabinet approved September 28 and 29, 2026, as special holidays for government offices in Bangkok, Nonthaburi, Pathum Thani and Samut Prakan. According to the Thai government, the measure is intended to reduce unnecessary travel and ease traffic disruption in areas affected by heavy rainfall and standing floodwater.
The measure does not constitute a nationwide public holiday. Essential government services, urgent duties and previously scheduled appointments that cannot reasonably be postponed may continue, with agency heads authorised to maintain necessary operations. Government services that can be provided online are also expected to continue. State enterprises, financial institutions, hospitals and private-sector organisations have been left to determine their own arrangements according to operational requirements and applicable laws.
Thousands Evacuated as Flooding Continues
The decision comes as Bangkok continues to deal with the effects of exceptionally heavy rainfall. Reuters reported on September 28 that around 320 millimetres of rain fell over two to three days—nearly equivalent to the amount of rainfall the low-lying capital normally receives during an entire September. The intense rainfall overwhelmed drainage systems and inundated neighbourhoods across the city.
According to the latest reports, more than 580,000 homes across 41 provinces have been affected by flooding since September 16, with at least eight deaths reported. In Bangkok, nearly 6,000 people had been moved to 234 evacuation centres, while more than 80,000 residents in flooded areas were reportedly unable to leave their homes.
Thailand's government has mobilised relief operations, including boats and mobile kitchens, with authorities aiming to provide food and essential assistance to affected residents during the flooding and for several days after water levels recede.
Drainage Operations Intensify
Rainfall in Bangkok began easing on September 28 as the low-pressure system responsible for the intense rainfall moved away. However, intermittent monsoon showers remain possible, and several areas continue to experience flooding.
Bangkok authorities are concentrating on lowering water levels in major canals to increase the capacity of the drainage network. About 329,000 households, representing roughly 700,000 people, have been affected in Bangkok, according to Thailand's government, while several districts have experienced particularly serious impacts.
Pumping operations are continuing, while authorities are working to reduce water levels in major drainage canals and reopen affected roads. Some major roads have become passable again, although several locations remain flooded and residents have been advised to exercise caution.
Economic Damage Mounts
The flooding is also creating a significant economic burden. Reuters reported that preliminary estimates put nationwide flood-related economic damage at at least 11 billion baht (approximately US$327 million), with losses potentially increasing if conditions deteriorate.
The flooding highlights the vulnerability of densely populated, low-lying urban areas to extreme rainfall and the importance of effective drainage, flood-management infrastructure, emergency preparedness and resilient urban planning.
Thailand's latest response demonstrates how extreme rainfall can affect not only homes and transportation but also the functioning of government and the wider urban economy. The temporary reduction in official travel is being used as an emergency measure while authorities continue evacuation, relief, pumping and drainage operations.
