Rain is here! 30% chance of rain, strong winds in Bangkok and upper Thailand

24-Hour Weather Forecast

A new moderate high-pressure system or cold air mass from China has extended over the upper northeastern region and the South China Sea. This condition causes southerly and southeasterly winds to bring moisture from the South China Sea and the Gulf of Thailand, covering the lower northern region, northeastern region, central region (including Bangkok and its vicinity), and the eastern region.

While Thailand experiences hot weather during the daytime, some areas will see thunderstorms, strong winds, and possible lightning strikes. Following this, temperatures in the northeastern region will drop by 1-2°C, while the northern region will remain cool to cold. The northeastern and central regions will experience cool weather in the morning.

Residents in affected areas are advised to take care of their health due to changing weather conditions and to be cautious of thunderstorms, strong winds, and possible lightning strikes. It is recommended to avoid open spaces, large trees, unstable structures, and billboards.

Farmers should take precautions to protect their crops from potential weather-related damage.

The weakening northeast monsoon over the Gulf of Thailand and the southern region is strengthening to a moderate level. This will bring increased rainfall to the southern region, while wind and waves in the Gulf of Thailand will become stronger. Waves in the lower Gulf of Thailand will reach 1–2 metres, while in the upper Gulf, they will be about 1 metre high. In areas with thunderstorms, waves may exceed 2 metres. Mariners in the Gulf of Thailand and the Andaman Sea are advised to navigate with caution and avoid areas with thunderstorms.
