South Korea’s October heat gives way to rain and a sharp temperature drop
South Korea saw unusually hot October weather on Monday, with daytime temperatures near or above 30°C in many areas.
Seoul reached 30.1°C and Daejeon 31.5°C, both described as October records in the available reports.
The heat is expected to ease as rain spreads across the country overnight and into Tuesday.
The forecast calls for 5 to 50 millimeters of rain in most areas, with more than 80 millimeters possible in the mountains of Jeju Island.
After the rain, colder air from the north is expected to bring a 5-to-10-degree drop by Wednesday morning, with strong winds making it feel colder.
Forecasters advise people to prepare for the sudden change; mostly clear weather is expected for a while, before more rain is forecast nationwide on Sunday.
South Korea’s unusually hot October weather is expected to give way to rain and a sharp drop in temperatures from October 13.
On October 12, Seoul reached 30.1°C and Daejeon reached 31.5°C, with the latter reported as a record October high for the city.
Rain was forecast to spread nationwide overnight and ease from western areas on October 13.
