Sweltering weather will likely continue until around Chuseok or Korean Thanksgiving on Sept. 19. The Korea Meteorological Administration on Tuesday forecast that the temperatures in mid-September will be higher than the 18-22 degrees Celsius of average years.
As a warm air mass approaches the Korean Peninsula from the southwest, the mercury will temporarily soar to the levels of hot summer days, it added. In late August, a lot of rain is expected due to unstable atmospheric conditions and transient cyclones.
The heat wave will last longer than usual because the North Pacific anticyclone is shrinking more slowly. Usually, high atmospheric pressure originating from the North Pacific, which brings hot weather to the peninsula in the summer months, diminishes gradually by alternatively expanding and contracting from mid-August, but that is not happening this year.
The anticyclone is expected to stay around until late August, protracting muggy weather with heavy rain on several days. The KMA forecast that in late August precipitation will be higher than in average years with 76-141 mm.
On Wednesday, the mercury will rise to 33 degrees in Seoul and 37 degrees in Deagu, Pohang and Ulsan.
Meanwhile, 919 patients had been treated for heatstroke this summer as of Monday, and 10 of them died, according to the Korea Centers for Disease Control and Prevention.
Most of the dead worked outdoors in the scorching sun. The center warned that the aged, children, and people suffering from hypertension, heart diseases or diabetes are especially at risk.
