The Thai government announced on Tuesday, Sept. 29, 2026, that standing floodwater in Bangkok is expected to clear within two to three days. Government spokesperson Ekkapob Pianpises stated that this timeline depends on the absence of additional rainfall, noting that heavy rain is currently not anticipated.
The announcement follows a period last week in which Bangkok received approximately 320 mm (12.6 inches) of rain over two to three days. According to government data, this volume nearly equals the city's typical total rainfall for the entire month of September.
Flood-related damage is estimated at more than $320 million. While Bangkok’s primary airports remained operational through the weekend, some baggage handling operations at Suvarnabhumi Airport were affected. On Monday, Sept. 28, 69 Thai Air Force personnel were deployed to support ground operations of flag carrier Thai Airways. As of Tuesday, Sept. 29, hundreds of bags remained in airport hallways, and Thai Airways reported the cancellation of eight flights due to the flooding and aircraft rotation.
Thai Airways reported that 34 of its flights were delayed on Monday and baggage from 52 flights between Sept. 26 and 27 was being delivered to passengers as of Tuesday. For passengers on the eight canceled Tuesday flights, the airline warned that additional cancellations or schedule changes remain possible.
The Thai cabinet was scheduled to meet on Tuesday, Sept. 29, to discuss recovery measures and long-term plans to address flooding. The immediate clearance of the city depends on weather conditions over the next 48 to 72 hours. If no further rain occurs, standing water is expected to be gone by Thursday, Oct. 1, or Friday, Oct. 2.
