Hot weather to greet June, with heavy rain expected in southern regions and Jeju

South Korea is set to experience hot weather on June 1, with temperatures expected to reach around 30 degrees Celsius across the country. However, the pleasant weather will be accompanied by heavy rain in the southern coastal areas and Jeju Island.

The Korea Meteorological Administration forecasts that heavy and abundant rainfall will occur from the afternoon in Jeju, and from early morning on June 2 in the southern coastal regions of Jeonnam and Gyeongnam, as well as Jeju. The rain is expected to spread to other parts of Jeonnam, southern North Jeolla Province, and Gyeongnam by the morning of June 2, and to Daegu and southeastern Gyeongbuk later that morning.

Rainfall amounts are predicted to range from 5 to 60 millimeters, with some areas along the southern coast potentially receiving over 80 millimeters, and Jeju's mountainous regions possibly seeing more than 150 millimeters. There is a possibility of heavy rain advisories being issued. Intense downpours, with hourly precipitation rates of 20 to 30 millimeters, are anticipated in some areas from early morning on June 2 (or late on June 1 in Jeju), necessitating caution against safety hazards like flooding.

Meanwhile, daytime high temperatures are expected to exceed 30 degrees Celsius in most regions. The apparent temperature may reach around 31 degrees Celsius in some areas, raising concerns about potential heat-related illnesses. The KMA advises the public to be vigilant. Air quality is expected to be good to normal across all regions.
