Thailand has declared a state of maximum environmental alert because of a "Super El Niño" that has caused the country’s highest temperatures ever recorded. In some northern and central areas, temperatures have gone over 45 degrees Celsius for nearly three weeks. The government has given stay-at-home orders and started large cooling measures, especially in big cities like Bangkok.

Officials have said these conditions are a severe public health hazard. Hospitals are seeing more patients with dehydration and problems caused by the heat, especially among older people, children, and outdoor workers.

Experts say this heatwave is due to an intense "Super El Niño" and long-term climate change. The government has set up emergency help, is giving out water, and has asked local authorities to stop outdoor activities during the hottest hours. Authorities say adaptation plans are important for the future.
