Seoul in June

Early June brings runs of clear days without the full summer humidity, a good window for outdoor plans. The midday sun is already strong, so bring a hat and sunscreen. The rainy season in central Korea normally begins around June 25, so umbrellas come out more often toward the end of the month.

Seoul in June ran hot: 28°C by day and 19°C at night. By midday the shade was the best seat in town. With about 7 rain days, showers were an occasional nuisance rather than the rule. Individual years ran between 3 and 12 rain days.

With up to 14.7 hours of daylight, dinner plans could still start in the light. About 6 days a month still climbed past 30°C, the ones where you looked for shade. Not every year was typical: 2012 ran 2.3°C warmer than the mean, with highs of 30.0°C. Rain days averaged 16 mm each, so when it rained it rained properly.

How long it rained

On a rainy day it rained for about 5.7 hours. Rain came at any time of day.
