BANGKOK, THAILAND – A life-threatening heatwave swept across Thailand as authorities warned residents and tourists to stay indoors or risk fatal heatstroke.
Record heat put Thailand on alert
Deputy government spokesperson Ayrin Phanrit raised the alarm over rapidly rising temperatures.
“Temperatures could rise to 42 to 43 degrees Celsius in high‑risk areas,”
said Ayrin Phanrit, deputy government spokesperson. Provinces such as Mae Hong Son, Lampang and Tak were identified as particularly affected, where the heat had become unbearable.
Conditions were also expected to be extreme in the rest of the country. Authorities described a heatwave that was draining people’s strength and stretching public health to its limits.
Deadly risk for thousands
Officials stressed that the danger was real and potentially fatal. Heatstroke could lead to the body overheating and vital systems failing. Older people, toddlers, babies and those with chronic illnesses faced the greatest risk.
People with heart or lung problems, as well as those with severe obesity, were warned they were in acute danger. Outdoor workers were also listed as a key risk group, for whom the heat had become a daily challenge.
How to survive the heat
The government issued clear behavioural guidelines to reduce the risk of heat-related illness. No one was advised to go outside between 11 a.m. and 3 p.m., described as the most dangerous period of the day. People were urged to drink large amounts of water and to avoid sugary soft drinks and alcohol, which officials said made the situation worse.
Residents and visitors were advised to wear loose clothing made from light fabrics. Authorities underlined that children or animals must never be left in parked cars, warning that this could become fatal within minutes.
What heatstroke really is
Health officials explained that heatstroke was not the same as ordinary sunstroke. In such cases, the body could no longer cool itself and core temperature rose rapidly. Dizziness, headaches, nausea and confusion were cited as early warning signs.
If no one intervened, the body could collapse. In the worst case, heatstroke could lead to organ failure and death, a risk officials framed as a medical fact rather than alarmism.
Wild weather across Thailand
While the north and northwest struggled with severe heat, other regions faced a different kind of extreme weather. Meteorologists predicted heavy thunderstorms from Tuesday to Friday. First the northeast was expected to be hit, followed by the east, the central region and Bangkok.
Forecasters warned of storms with thunder and lightning but little real relief from the heat. High humidity meant the perceived temperature would remain extremely uncomfortable despite the unsettled weather.
Air quality remains moderate
Authorities reported at least one positive development: air pollution remained limited. Moderate winds and expected rain were helping to maintain clear visibility. Measured values were in the low to moderate range, making breathing largely safe for the time being.
However, officials cautioned that this situation could change quickly. They said the overall weather and health situation in the country remained tense.
Advice for tourists
Visitors on holiday in Thailand were urged to take the warnings seriously. Long sightseeing tours in the midday heat were strongly discouraged. Tourists were advised to adjust their plans to protect their health.
Authorities recommended visiting temples and other attractions early in the morning or in the late afternoon. During midday, people were encouraged to rest in air‑conditioned cafés or hotel rooms and to carry a bottle of water at all times, to ensure a dream trip did not turn into a nightmare.
Government calls for solidarity
The government appealed to communities to look out for vulnerable neighbours. People living alone, especially older residents, were considered particularly at risk in the heat. Officials suggested simply knocking on a neighbour’s door, asking if they were all right, or offering a glass of water.
They stressed that small gestures could save lives during the current conditions. The heatwave was expected to last for several more days, and authorities said Thailand had to endure this period together, including everyone living in or travelling through the country.
