Bangkok opens hundreds of cooling centres as extreme heat intensifies

Authorities in Bangkok have opened more than 300 free cooling centres across the city as prolonged extreme heat continues to affect large parts of Thailand.

The initiative follows three consecutive weeks of intense temperatures, with the heat index—combining temperature and humidity—rising above 50°C in some areas.

The Bangkok Metropolitan Administration said the heat index has remained in a critical range of 42°C to nearly 52°C since the beginning of April.

While April is typically the hottest month in Thailand, officials say rising temperatures in recent years have intensified public health concerns.

Health authorities have warned that prolonged exposure to extreme heat can lead to serious health risks, urging residents to avoid direct sunlight during peak hours and to watch for symptoms such as dizziness, fatigue and heat cramps.

The cooling centres include air-conditioned public facilities such as libraries, health offices, schools and government buildings, alongside shaded outdoor spaces designed for temporary relief.

Local reports, including the Bangkok Post, indicate that tens of thousands of people have already used the centres in recent weeks.

Residents are using the facilities not only to escape the heat, but also as places to rest, work and study. Meanwhile, tourists and wealthier residents are largely seeking relief in air-conditioned malls and restaurants.
