On 23 July 2026, the Meteorological Department's website posted the daily weather forecast and general conditions.
Heavy rain is forecast in parts of the northern, northeastern, central regions including Bangkok and its vicinity, and the eastern region due to the southwest monsoon covering the Andaman Sea, Thailand, and the Gulf of Thailand with moderate strength, along with a low-pressure area over northern Vietnam. Residents in upper Thailand are advised to be cautious of dangers from heavy and accumulated rain.
In the upper Andaman Sea and upper Gulf of Thailand, waves reach 1-2 meters high, while in the lower Andaman Sea waves are about 1 meter high. Areas with thunderstorms may see waves exceeding 2 meters. Mariners are urged to navigate cautiously and avoid sailing in areas with thunderstorms.
