Seoul in July The month with the most rainy days. The rainy season does not mean rain every day; it tends to pause for a few days, then pour all at once. Once it ends, usually in the last week of July, hot nights set in. Sandals or rain boots that can get wet make getting around easier.
It was a hot month: 30°C by day and 23°C after dark. Rain fell on 14 days of the month on average. A visitor in 2014 met 7 rain days; one in 2013 met 24. The average of 14 hid that gap.
Rain picked up sharply from July, up from 7 days the month before to 14. Daylight lasted 14.1 to 14.7 hours a day, so evenings stayed bright. Highs topped 30°C on 13 days of the month on average. Mixing in indoor stops at midday made sense. July 2021 averaged 32.3°C by day, 2.8°C above the 20-year mean.
How long it rained On a rainy day it rained for about 7.5 hours. Rain came at any time of day.
