24-Hour Forecast:

Mountain peaks and highland areas will experience cold to very cold conditions, with some areas seeing frost.

Weather Advisory for Thailand

The public is advised to take care of their health due to the persistently cold weather conditions. Additionally, caution is urged to prevent fire hazards caused by the dry air, and extra care is recommended when travelling through areas with fog. These conditions are attributed to a moderate high-pressure system or cool air mass covering upper Thailand and the South China Sea.

The northeastern monsoon prevailing over the Gulf of Thailand, southern Thailand, and the Andaman Sea has weakened, leading to reduced rainfall in the lower southern region. Waves in the Gulf of Thailand and the Andaman Sea remain moderate, with wave heights of approximately 2 meters in the lower Gulf of Thailand and 1–2 meters in the upper Gulf.

In areas experiencing thunderstorms, waves may exceed 2 metres. The Andaman Sea has wave heights of about 1 meter, and further offshore, waves range from 1 to 2 meters. Mariners in these areas are advised to exercise caution and avoid sailing in regions with thunderstorms.

Air Quality Update

Current Weather Conditions Affecting Dust Accumulation:

Air ventilation remains in the "poor to weak" category. The weakening winds over upper Thailand, combined with persistent surface-level temperature inversions, have restricted the dispersion of air pollutants. As a result, the concentration of particulate matter (PM) is expected to increase.
