Thailand Weather Forecast: February 6, 2026 – Fog, Rising Temperatures, and Approaching Storms
Table of Contents
Thailand is experiencing a period of fluctuating weather conditions, with a mix of rising temperatures, morning fog, and the potential for thunderstorms and strong winds in the coming days. The Thailand Meteorological Department is advising residents to take precautions as conditions shift across the country.
Regional Overview: A Nation in Transition
Currently, upper Thailand is seeing a weakening of the high-pressure system that previously brought colder temperatures. This is resulting in warmer conditions, though morning fog remains a concern in many areas. Meanwhile, the southern region is bracing for continued thunderstorms due to the influence of the moderate northeast monsoon.
Temperature Trends and Regional Details
Across much of the country, temperatures are expected to rise by 1-2 degrees Celsius over the next 24 hours. Here’s a detailed breakdown by region:
Northern Thailand
The north will experience cool to cold temperatures with morning fog. Minimum temperatures are forecast between 15-20°C, while maximums will reach 32-36°C. Mountainous areas will be significantly colder, with lows potentially dropping to 6-14°C. Easterly winds will be blowing at 10-15 km/hr.
Northeastern Thailand
Similar conditions are expected in the northeast, with cool to cold weather and some morning fog. Lows will range from 14-21°C, and highs will be 34-36°C. Mountain tops will see the coldest temperatures, dipping to 10-15°C. Easterly winds will also be present at 10-15 km/hr.
Central Thailand
The central region will be cool with some morning fog, and temperatures will rise slightly. Minimum temperatures are predicted to be 19-22°C, with maximums reaching 34-36°C. Easterly winds will be blowing at 10-15 km/hr.
Eastern Thailand
The eastern region will be cool, particularly in the upper areas, with some morning fog. Temperatures will rise 1-2 degrees Celsius, and light rain is possible, especially along the coast. Lows will be 21-25°C, and highs will be 31-35°C. Southeast winds will be stronger, at 15-30 km/hr, with sea waves less than 1 meter high.
Southern Thailand
The southern region is divided in its forecast. The east coast will experience cool mornings and a 10% chance of thunderstorms, primarily in Surat Thani and Nakhon Si Thammarat provinces. Wave heights in the Gulf of Thailand are expected to be moderate, ranging from 1-2 meters, potentially exceeding 2 meters during thunderstorms. The west coast also has a 10% chance of thunderstorms, mainly in Phang Nga and Krabi provinces, with similar wave conditions.
Bangkok and Surrounding Areas
Residents of Bangkok and surrounding areas can expect some morning fog and a slight temperature increase. Minimum temperatures will be 23-25°C, and maximums will reach 33-35°C. Southeast winds will be blowing at 10-15 km/hr.
Approaching Storms and Air Quality Concerns
Looking ahead, a significant weather shift is anticipated between February 8-11, 2026. A moderate to strong cold air mass from China is expected to move over upper Thailand and the South China Sea, bringing thunderstorms, dropping temperatures, and increasing wind speeds. This system will be accompanied by easterly and southeasterly winds carrying moisture, potentially leading to widespread rainfall.
In addition to the changing weather, authorities are also addressing concerns about air quality. Moderate to considerable accumulation of dust and smog has been reported in the northeastern, central, and eastern regions, as well as the Bangkok metropolitan area, due to poor ventilation and weakened winds.
A senior official stated that residents should “take care of their health due to the changing weather conditions and increased air pollution.” Boaters in the Gulf of Thailand and the Andaman Sea are urged to navigate with caution due to potentially hazardous wave conditions.
The Meteorological Department will continue to monitor the situation and provide updates as the weather patterns evolve.
