South Korea Weather: Highs of 30 C, rain on coasts and Jeju Island

South Korea is set for a mixed weather day on Tuesday, with the central region enjoying mostly clear skies while the eastern and southern coasts, along with Jeju Island, anticipate rain. The Korea Meteorological Administration forecasts that the rain, influenced by a high-pressure system in the northern East Sea and a low-pressure system south of Jeju, will be light, not exceeding 5mm in most areas.

However, Jeju Island is expected to receive a more significant amount of rainfall, between 20 to 60mm, continuing into Wednesday. This precipitation may be accompanied by strong winds, raising the possibility of a strong wind advisory for the island. Coastal areas, particularly along the east coast, should also be wary of strong waves and swells that could reach over seawalls and breakwaters.

Daytime high temperatures are predicted to range from 22 to 30 degrees Celsius across the country. Cities like Seoul and Incheon will reach 30 degrees, while coastal cities such as Busan and Jeju will be cooler at 24 and 23 degrees respectively. The weather is expected to remain consistent with early summer conditions, neither too hot nor too cold, for the time being.
