Inland regions of South Korea recorded temperatures approaching 30 degrees Celsius on April 13, signaling an early summer surge even as highs persist into April 14.
Record-Breaking April Temperatures
Gyeonggi Province’s Gapyeong-gun reached 29.7 degrees Celsius after 3 p.m., while Gyeongnam’s Gimhae hit 28.8 degrees Celsius at midday—the highest mid-April reading since observations began amid the 2008 financial crisis.
In Gyeongnam’s Tongyeong, temperatures climbed to 25.0 degrees Celsius, matching the mid-April peak from the January 1968 economic crisis. Seoul peaked at 27.3 degrees Celsius, 10 degrees above the monthly average of 17.3 degrees Celsius.
These extremes stem from a high-pressure system covering most of the country, excluding Jeju Island, which fueled strong northerly winds.
