Thai authorities have issued a warning indicating that temperatures could surpass 52ºC, as indicated by the heat index, a measure combining temperature and humidity.

According to AFP, the country's health ministry reported 30 deaths from heatstroke between January 1 and April 17 this year, compared to 37 deaths in the entirety of last year.

The heat index has indicated an "extremely dangerous" level of temperature.

AFP also reported that Bangkok reached 40.1ºC on Wednesday, April 24, with similar temperatures anticipated in the upcoming days.

The Nation reported that Bangkok's weather is expected to reach 41ºC today, April 26.

Individuals have been advised to remain indoors for prolonged periods to prevent heatstroke, which occurs when the body's temperature exceeds 40ºC.

Thailand's Department of Disease Control deputy director-general, speaking to AFP, emphasized the importance of urging the elderly and individuals with underlying medical conditions, including obesity, to stay indoors and stay hydrated.

Typically, April marks the hottest time of the year in Thailand. However, the El Niño weather pattern has exacerbated the situation.

El Niño is a climate pattern characterized by abnormal warming of surface waters in the eastern tropical Pacific Ocean. It brings drier and warmer conditions to most of Southeast Asia while causing heavy rainfall and unusual weather phenomena elsewhere.

The Thai Meteorological Department forecasts "hot and hazy weather" during the daytime for most of Thailand, with isolated thundershowers from today until May 2. Temperatures may range between 41ºC and 44ºC in the coming days.
