For millions of people in South and Southeast Asia, the stiflingly hot and humid heat wave began long before the summer. April and May are usually the hottest months of the year in the region, as temperatures rise until the annual monsoon rains bring relief.
India’s hot season began abnormally early, recording its hottest February in history. In mid-April, New Delhi saw temperatures soar above 104 degrees Fahrenheit (40 degrees Celsius). At least 11 people died of heat stroke on a
single day. Temperatures were abnormally high in May, too.
India’s intense heat wave continued in June, when
hospitals feared that the punishing temperatures were leading to a higher-than-usual number of deaths among patients. Monsoon rains have cooled temperatures across the country in recent weeks.
The heat wave in South Asia also seared Bangladesh in April, when Dhaka, the capital, hit 105 degrees Fahrenheit, (41 degrees Celsius), its highest temperature in six decades. The Bangladesh Meteorological Department said that it had not seen such a prolonged heat wave since the 1970s.
As Vietnam broke its record at 112 degrees Fahrenheit (44 degrees Celsius) in May, increased demand for air conditioning stretched its power grid, prompting the authorities to turn off streetlights and ration electricity. Laos, which neighbors Vietnam, recorded its highest-ever temperature on the same day, also reaching 112 degrees Fahrenheit (44 degrees Celsius).
Thailand also set a national record in April when temperatures peaked past 114 degrees Fahrenheit (45 degrees Celsius). Temperatures there remained high despite several summer storms, until the unusual heat subsided this month. Meteorologists said they still expected above normal temperatures throughout the summer.
