Seoul drops to 2C on Wednesday morning, Oct. 28, and rain of 5-10 mm is forecast for the city on Thursday, Oct. 29. Add a layer.
6-11C on Tuesday, 2C in Seoul on Wednesday morning
The Korea Meteorological Administration forecasts a Seoul low of 2C for the morning of Wednesday, Oct. 28, and -2 to 3C across the capital region. Tuesday morning was 6-11C with highs of 15-17C, so the step from autumn into early winter comes in a single night.
Nationwide, morning lows run from -2 to 7C and highs from 11 to 16C.
The wind makes it colder than the thermometer
Tuesday brings gusts of 70 km/h or more along the coast and in the south, and 90 km/h or more in the mountains. Wednesday morning still has gusts of about 55 km/h nationwide and 70 km/h in the mountains.
Inland, the gap between day and night is 10-15C. You leave in the morning cold, meet 12-14C at midday, and it drops again after sunset.
Thursday: 5-10 mm of rain in Seoul
Rain arrives on Thursday, Oct. 29: 5-10 mm in Seoul and southern Gyeonggi, 5-20 mm in Incheon, northern Gyeonggi and the West Sea islands. Nationwide lows are -1 to 8C with highs of 12-18C.
If a palace or Han River walk is on your list, Wednesday daytime is the steadier window; bring an umbrella for Thursday.
