Temperatures rose to over 30 degrees Celsius in Seoul for the fourth straight day on Sunday, making this the hottest May in 66 years, the Korea Meteorological Administration said.
The last time the mercury climbed over 30 degrees in May was in 1950 when it happened for four consecutive days between May 27 and 30.
Temperatures reached 32 to 33 degrees in Seoul from Thursday to Sunday last week and around 30 degrees in other parts.
The KMA blamed hot air carried into Korea from Mongolia and northern China by northwesterly winds and trapped here by an anticyclone.
The number of days in May when temperatures exceeded 30 degrees in Seoul rose from 0.2 days in the 1980s to 1.7 days in the 2010s.
The heat wave will gradually wind down starting Monday with rain forecast nationwide for Tuesday.
Monday’s high is forecast at 29 degrees, plunging to 18 to 23 on Tuesday across the country before the rain stops on Tuesday night.
