Heat Intensifies Across Upper Thailand as Rainfall Declines While Southern Provinces Face Ongoing Storms
Weather authorities say easing rain in northern regions is driving hotter daytime temperatures, while stronger winds continue to bring thunderstorms to the South
Temperatures are rising across much of upper Thailand as rainfall decreases, while southern provinces continue to experience scattered storms and periods of heavy rain, according to the latest national weather outlook.
Meteorological officials say the shift reflects weakening moisture flows over the northern half of the country.
With fewer rain clouds forming, daytime heat is becoming more intense across the North, Northeast, Central Plains and parts of the East, where hot conditions now dominate the daily forecast.
Daytime temperatures in several areas are expected to climb into the mid-thirties Celsius, with isolated thunderstorms occurring only in limited locations.
The change is linked to a regional weather pattern in which high-pressure systems extending from China interact with easterly and south-easterly winds across mainland Southeast Asia.
These conditions reduce rainfall in the upper regions while allowing heat to build during the day.
Weather officials have advised residents to take precautions against heat exposure and remain alert to sudden thunderstorms and gusty winds that can still develop in some provinces.
In contrast, southern Thailand continues to experience unsettled conditions.
Moist easterly winds moving across the Gulf of Thailand, the Andaman Sea and the southern peninsula are generating thunderstorms in several coastal and inland areas.
Some provinces along the east coast of the South may experience heavier downpours as the weather system strengthens.
The maritime outlook also reflects the unstable conditions in the South.
Waves in parts of the Gulf of Thailand may reach around one to two metres and become higher during thunderstorms, prompting warnings for small boats and fishermen to avoid storm-affected waters.
The developing weather pattern is typical of Thailand’s seasonal transition period, when hot conditions intensify across inland regions before the arrival of more consistent monsoon rainfall later in the year.
Meteorologists say the combination of rising heat and intermittent storms may continue in the coming days as atmospheric systems shift across the region.
Authorities are urging residents across the country to monitor local forecasts, remain cautious during thunderstorms, and protect crops and outdoor structures from sudden strong winds that can accompany short-lived summer storms.
