Red-level heat index grips Phuket while Bangkok and 34 other provinces brace for dangerous conditions.
PHUKET, Thailand — With temperatures climbing into territory deemed “very dangerous” by health authorities, large swathes of Thailand are reeling under a ferocious heatwave that has prompted urgent warnings from the Department of Health. On Wednesday, the island province of Phuket registered a red-level heat index—an alarming metric that factors both temperature and humidity—while Bangkok and 34 other provinces were placed under an orange-level heat alert.
Officials say the blistering conditions will persist into Thursday, raising serious health concerns, especially for the elderly, people with pre-existing health conditions, and those working outdoors.

When Heat Feels Hotter Than It Is
“The heat index is the temperature people actually feel on their bodies, which can be much higher than the recorded air temperature,” said Dr. Amporn Benjaponpitak, Director-General of the Department of Health. In red-level conditions, the index can make it feel like over 52°C (125.6°F), even if thermometers show a lower number.
This level of heat poses life-threatening risks including heatstroke, exhaustion, fainting, and even death. “Senior citizens, individuals with chronic illnesses, people with obesity or mental health issues, and those who consume alcohol regularly should exercise extreme caution,” Dr. Amporn added.
Alongside Phuket, an orange alert—where it feels like 42°C to 51.9°C—was issued for 34 provinces including Bangkok, Chiang Mai, Rayong, Chon Buri, and Ubon Ratchathani, among others.
“These are not just numbers,” warned Dr. Thiti Sawangtham, Deputy Director-General of the Department of Health. “Prolonged exposure under these conditions can lead to cramps, confusion, and life-threatening heatstroke.”
Staying Safe in a Scorching Climate
The Health Department has issued a set of guidelines to help residents endure the extreme heat:
- Hydrate constantly: Drink water regularly, not just when thirsty.
- Avoid alcohol and sugary drinks, including sodas and syrups, which may worsen dehydration.
- Wear breathable clothing: Light, loose-fitting garments with good ventilation are best.
- Know the warning signs: Red or hot skin, rapid pulse, headaches, disorientation, hallucinations, or speech issues warrant immediate attention.
“In suspected cases of heatstroke, priority should be given to rapid cooling—apply ice or cold water to the neck and armpits—before transporting the person to the nearest hospital,” said Dr. Thiti.
Thailand’s punishing heatwave adds to growing concerns about the rising frequency and severity of extreme weather events in the region, often linked to global climate change. With April typically being one of the hottest months in Thailand, this year’s escalation in the heat index could be a preview of what’s to come if mitigation efforts falter.
In the meantime, authorities urge all residents to treat the heat with the seriousness it demands.
“This isn’t just about discomfort,” Dr. Amporn said. “It’s about survival.”
