The Thai Meteorological Department (TMD) has issued a weather alert forecasting turbulent conditions across Thailand from February 20th to 25th, urging residents and travelers to brace for thunderstorms, strong winds, and a significant drop in temperatures. The unsettling forecast, announced on Wednesday, February 19th, spans the entire country, with varying impacts expected across different regions.
TMD issues weather advisory for cold weather and strong winds from January 10th-13th
February 20th–22nd: Scattered Storms and Rising Humidity
From Thursday, February 20th, to Saturday, February 22nd, southerly and southeasterly winds will sweep humidity from the South China Sea and the Gulf of Thailand into northern Thailand, triggering scattered thunderstorms. The TMD predicts that these storms will bring brief but intense rainfall to the region, potentially disrupting outdoor activities and travel. Meanwhile, moderate northeast monsoon winds prevailing over the Gulf of Thailand and the Andaman Sea will spark isolated thunderstorms in southern Thailand. Coastal areas in the lower Gulf can expect waves reaching 1-2 meters, prompting caution for small vessels and beachgoers.
February 23rd–25th: Cold Front, Hail, and Temperature Drop
The weather is set to intensify from Sunday, February 23rd, through Tuesday, February 25th, as a cold air mass from China descends over northeastern Thailand. This frigid front, combined with westerly winds blowing in from Myanmar, will create a volatile mix, unleashing thunderstorms, gusty winds, and even hail in some northern and northeastern areas. The TMD warns that these conditions could lead to property damage and pose risks to agriculture, particularly in vulnerable rural zones.

Following the storms, temperatures are expected to plummet, with the northeast facing a sharp drop of 2-4°C, while central and eastern regions, including Bangkok, will see a more moderate decline of 1-2°C. The cooler air will bring a rare chill to the capital, offering respite from its usual humidity but catching many residents off guard after weeks of warmer weather.
South Faces Heavy Rain and Rough Seas
Southern Thailand will not escape the weather shift, as increased rainfall and heavy downpours are forecast to drench the region. The lower Gulf of Thailand will experience heightened wave activity, with swells rising to 2-3 meters and exceeding 3 meters during thunderstorms. The Andaman Sea and upper Gulf will also see rough seas, with waves likely to disrupt ferry services and fishing operations. The TMD has advised mariners to exercise caution and urged coastal communities to prepare for potential flooding.
Public Advisories and Preparedness
The TMD has called on the public to stay informed through regular updates, warning of possible flash floods and landslides in hilly or low-lying areas, particularly in the north and south. Farmers are advised to protect crops and livestock from sudden storms and temperature changes, while drivers should anticipate reduced visibility and hazardous road conditions during heavy rain and wind gusts. In Bangkok, officials are monitoring drainage systems to mitigate urban flooding risks as the cold front approaches.
Cool Weather, Strong Winds Expects Across Thailand
This weather event marks a dramatic shift from Thailand’s typical late-February climate, blending monsoon-like conditions with an unusual cold snap. Meteorologists attribute the pattern to a unique convergence of regional weather systems, a phenomenon that could signal more unpredictable shifts in the weeks ahead. As the nation prepares for this turbulent stretch, the TMD continues to monitor developments and will provide further updates as the situation evolves.
