By the end of August the summer heat will have gone, the Korea Meteorological Administration said Monday.
In August, the average temperature fell 4.3 degrees Celsius compared to last summer, when the nation was gripped by unusually hot weather. The average daily high stood at 28 degrees from Aug. 1 to 17, much cooler than the 32.3 degrees in August last year.
It was also 1.8 degrees lower than the 30-year average of 29.8 degrees between 1981 and 2010. The number of sultry days with the day's high reaching over 33 degrees also fell from 18.2 days last year to 6.1 days this year. This year saw just 3.2 tropical nights this summer, down from last year’s 15.8.
The KMA attributes this year's relatively mild temperatures to typhoons since late July including Neoguri and Halong, which kept the day temperatures down.
"During the rainy season this year, the nation hardly saw any heavy monsoon downpours, resulting in sweltering weather in early summer. But at the height of summer several typhoons affected the country, reducing average temperatures," a weatherman said.
As a result, the number of patients with heat-related illnesses like heatstroke decreased significantly this summer. According to the Korea Centers for Disease Control and Prevention, 537 patients visited emergency rooms with heat-related complaints between June 1 and July 17, around half of last year's 1,070 and a 40 percent drop from 2012 when the figure was 905.
The death toll from heat-related illnesses stood at just one this year, as against 11 over the same period last year.
Meanwhile, rain is expected to continue nationwide until Tuesday. The weather agency forecast that thunderstorms will continue in the southern part of the country until Wednesday.
