Clear skies and highs of 31 C, with rain forecast for South Korea’s east coast and Jeju

Friday will bring mostly clear skies across South Korea, but parts of the east coast and Jeju will see rain. Highs are forecast to reach 26 C to 31 C, while Jeju, under a heat alert, could record perceived temperatures around 33 C.

The Korea Meteorological Administration expects rain in the Gangwon east coast and mountainous areas from between 9 a.m. and noon, with conditions easing in many places after 3 p.m. Jeju could see rain until 6 p.m. Forecast amounts range from 5 to 10 millimeters in the Gangwon mountains, less than 5 millimeters on the Gangwon coast and 5 to 20 millimeters on Jeju.

Rain could reduce visibility and make roads slippery. Strong winds will also affect most regions, with gusts exceeding 55 kilometers per hour and reaching 70 kilometers per hour in mountainous areas. Wind alerts are already in effect along the Gyeongsang coast and Jeju, and additional alerts may be issued for the southern Jeolla coast and areas near Jirisan.

Fog could reduce visibility to less than one kilometer in inland Gangwon until 9 a.m. Dense fog below 200 meters is also expected in the Gangwon mountains as easterly winds bring low clouds. Temperatures will remain similar to or slightly above seasonal averages, and perceived temperatures in the Jeolla region are expected to reach around 31 C. Fine dust concentrations should remain at good levels nationwide.
