BANGKOK, THAILAND – The Thai Meteorological Department warned of intensifying heat and recurring thunderstorms across Thailand from 22 to 27 March 2026.
What Was Behind the Weather Pattern
On 22 and 23 March, southern to southeasterly winds strengthened over the northeast and east, while a low-pressure heat system remained over the upper part of the country.
This combination brought more rain with thunderstorms to the affected regions, including gusty winds and isolated hail.
From 24 to 27 March, conditions across upper Thailand became hotter overall, with some areas in the north and central regions experiencing very hot temperatures.
Thunderstorms still remained possible, as the heat low persisted even though the southern and southeasterly winds over the northeast and east weakened during this period.
North: Up to 40°C and Hail Risk
In the north, daytime weather on 22 and 23 March remained hot, with thunderstorms expected over 10 to 20 percent of the area, along with local hail and strong gusts.
From 24 to 27 March, maximum temperatures between 34 and 40°C were forecast, with thunderstorms expected in around 10 percent of the region and isolated strong winds.
Northeast and East: More Showers Early in the Week
In the northeast, the probability of thunderstorms on 22 and 23 March ranged from 20 to 40 percent, accompanied by gusty winds and local hail.
In the east, the same 20 to 40 percent probability applied at first, before values between 24 and 27 March decreased to 10 to 30 percent depending on the specific area.
Central Thailand: Very Hot, Storms Still Possible
In the central region, forecasts for 22 and 23 March indicated maximum temperatures between 33 and 38°C, with thunderstorms expected over 10 to 20 percent of the area and local hail.
From 24 to 27 March, peak temperatures in parts of the region were expected to rise to up to 40°C, while the likelihood of thunderstorms remained at around 10 percent.
Bangkok: Hot and Humid with Isolated Storm Cells
For Bangkok and surrounding areas, hot daytime weather was forecast throughout the entire period, with thunderstorms expected over 10 to 30 percent of the city.
The forecast also included isolated strong gusts, with minimum temperatures between 25 and 27°C and maximum temperatures from 34 to 38°C.
South and Sea: Isolated Showers, Waves Around 1 Meter
Along the east and west coasts of the south, isolated thunderstorms were expected across 10 to 20 percent of the area for the entire period.
At sea, waves in the Gulf of Thailand were predicted to weaken, generally reaching around 1 meter in the lower gulf, but topping 1 meter during thunderstorms.
Warnings and Advice from the Weather Service
The Thai Meteorological Department advised people in upper Thailand to avoid open spaces during thunderstorms and not to seek shelter under large trees, near unsecured structures, or close to billboards.
Farmers were urged to secure fruit trees and take precautions against damage to crops and livestock, while also paying particular attention to their health due to the persistent heat.
