Southeast Asia is facing a devastating heat wave, with record-breaking temperatures being recorded in Vietnam, Laos, and Thailand. The heat wave has caused misery for millions of people in the region, and has been compounded by intense smoggy conditions which have led to a spike in pollution levels.
On Saturday, the northern district of Tuong Duong in Vietnam recorded the highest temperature ever recorded in the country, reaching 44.2 degrees Celsius. In neighboring Laos, the city of Luang Prabang reached 43.5 degrees Celsius, breaking the national record set just last month. The Laotian capital Vientiane also broke its all-time record this weekend with a temperature of 42.5 degrees Celsius. Meanwhile, Bangkok, the capital of Thailand, experienced its hottest ever temperature on Saturday, reaching 41 degrees Celsius.
The heat wave has been ongoing since late March, with temperatures in the upper 30s to low 40s Celsius being recorded across large parts of Thailand. In mid-April, the city of Tak in the northwest of the country became the first place to surpass 45 degrees Celsius.
The impacts of the climate crisis are exacerbating the severity and frequency of heat waves in the region. A 2022 study predicts that dangerous heat waves, defined as temperatures of 39.4 degrees Celsius and above, will occur three to ten times more often by the end of the century. The study also found that days of “extremely dangerous heat” could double, putting the populations of affected countries at risk.
Despite the expected return to more average temperatures in the coming days, the increasing frequency of unprecedented heat events poses a serious threat to the people of Southeast Asia. The lead author of the 2022 study, Lucas Vargas Zeppetello, has expressed concern about the future impact of these heat waves, stating that "heat waves in the past few decades have already been extremely deadly and there is serious cause for concern in the future.”
