For the first time in the country's history, South Korea saw a lower average temperature in July than in June.
This so-called "inversion phenomenon" occurred as the weather in July cooled down due to the monsoon after the record-breaking heatwave in June.
According to the Korea Meteorological Administration on Thursday, the average temperature of July this year was 22.7 degrees Celsius, 1.8 degrees lower than usual.
This is because the country has had continuous rain during July, preventing the temperature from going up as high as in normal years.
The long monsoon was caused by strong cold air that stayed over the northwest of the country, preventing the monsoon from moving up the country.
"As the temperature in the Arctic goes up, the cold air flow that normally moves toward the East Sea has been blocked so it flew either to the West or to the North. South Korea is affected by the cold air that came down from the northern part of the country."
The unusual weather has caused a lot of damage this year, and the government is looking at more options to deal with the situation.
South Korean President Moon Jae-in on Thursday designated an additional 11 areas as special disaster zones, promising prompt support from the government.
"This second round of designations come after the interior ministry inspected the damage in flood-hit areas in advance of local governments asking for the designation. The administration will respond quickly to people that have been affected."
Now the total of 18 regions including parts of Jeolla-do and Gyeongsangnam-do provinces will receive financial aid as well as support for restoration work.
The government is also considering further support for those areas that are in need but have not yet been designated as disaster zones.
The monsoon in South Korea is expected to last until August 16th and another round of heavy rain of up to 300mm is forecast for the capital region on Friday.
