Thailand Weather Update: Rain Relief Amidst Thunderstorm Alerts for August 2025

The rhythmic patter of rain has woven itself into the daily soundtrack of Thailand’s residents, yet today’s forecast from the Thai Meteorological Department (TMD) offers a smidge of hope, promising a slight break from the rain’s relentless symphony. Still, certain regions won’t escape the clap of thunder and the deluge of downpours. In particular, those dwelling in the upper northeastern areas have been advised to brace themselves against the skies’ impending watery assault. This meteorological dance is primarily attributed to a low-pressure system currently hovering over northern Vietnam, in concert with a now-feebler southwest monsoon that once danced vigorously over the Andaman Sea, Thailand, and the Gulf of Thailand.

Like a grand meteorological theatre, a total of 36 provinces have made their debut in today’s weather advisory, set to host splashes of rain—particularly northern and northeastern Thailand will experience nature’s boisterous showers. Offstage, conditions are more restrained over the maritime expanses of the Andaman Sea and the Gulf of Thailand, with the sea’s waves expected to tango gently at heights of 1 to 2 meters, and crescendo beyond 2 meters in areas where storms decide to take the spotlight. Mariners are being coached to tread these waters with caution and to steer clear of areas where tempests brew.

In the northern regions, a tempestuous performance is anticipated over 30% of the area. Audiences in Mae Hong Son, Chiang Mai, Chiang Rai, Phayao, Nan, and Tak provinces are among the lucky viewers. Thermometers are expected to flaunt numbers ranging from a modest 23-26°C at dawn to a toasty 32-35°C when the sun takes center stage, all while southwesterly winds whisper at speeds of 10-20 km/h.

Meanwhile, over in the northeastern region, a similar 30% of the area stands under the threat of thunderstorms, with Bung Kan, Sakon Nakhon, and Nakhon Phanom provinces set to witness nature’s dramatic displays. Temperatures will pirouette between 25-26°C in the early hours and ascend to 34-35°C as the day unfurls, with southwesterly winds once again playing a gentle accompaniment at the same 10-20 km/h.

Central Thailand won’t be left out, as 30% of this region’s terrain too anticipates the clash of clouds. Notable hotspots like Nakhon Sawan, Uthai Thani, Kanchanaburi, and Ratchaburi are expected to bask under temperatures shifting from 25-26°C to a balmy 35-36°C, with southwesterly winds whispering through at the same steady speed.

Eastern promises are also etched in today’s forecast, where thunderstorms will prance across 30% of the region, with areas like Nakhon Nayok, Chanthaburi, and Trat being the main acts. With temperatures waltzing between 25-28°C at their tamest and soaring to 32-36°C at their summit, southwesterly winds will continue their breezy melodies, swaying between 15-35 km/h. As the sea joins the stage, waves are expected to ripple at heights between 1-2 meters, with the terrors of thunder bolstering them above 2 meters.

Venture further south to the east coast, where thunderstorms will daintily encompass 20% of the area, teasing residents in Phetchaburi, Prachuap Khiri Khan, Chumphon, Pattani, Yala, and Narathiwat provinces. With temperatures coursing between 24-26°C at their gentlest to a sweltering 34-37°C, southwesterly winds at 15-30 km/h will flirt with offshores, and waves will modestly ripple around 1 meter, with stormy seas lifting them to 1-2 meters.

For the southern region’s west coast, prepare for nature’s encore, albeit across a subtler 20% of the area. Expecting a show in provinces like Ranong, Phang Nga, and Phuket, temperatures will flex between 24-28°C and max out at 33-36°C. Navigators will find southwesterly winds ranging from a playful 15-35 km/h from Phuket upwards, with waves swaggering between 1-2 meters, and getting feisty beyond 2 meters in stormy conditions. From Krabi down, expect winds to tone down to 15-30 km/h with waves curated around 1 meter, but elevating to 1-2 meters when storms steal the show.

Meanwhile, in the bustling epicenter of Bangkok and its fringes, the city expects a mild 20% of its landscape to be graced by thunderstorms. With temperatures balancing between a snug 26-27°C during the cooler hours and surging to 34-36°C when the sun reigns supreme, southwesterly winds will serenade the city at a soft 10-20 km/h.

The TMD persistently keeps an eagle eye on the unfolding weather drama, urging citizens to exercise prudence as nature unfurls its unpredictable plot across the landscape.
