July is Korea’s hottest and most humid month, sitting at the intersection of the summer rainy season (jangma) and the full heat of the Korean summer. The rain typically ends in mid-July, at which point temperatures climb, and the beaches fill.
Korea’s summer festivals, night markets, and Han River culture are at their peak in July, and anyone who can handle the heat and humidity will find Korea genuinely exciting.

FAQ
Is July a good time to visit Korea?
For beach and outdoor summer culture, yes. For sightseeing palaces and temples, no: the heat and humidity make outdoor historical sites uncomfortable during midday. July in Korea rewards those who embrace the summer culture (beaches, festivals, evening Han River) rather than the historical sightseeing circuit. See the best time to visit Korea for the full seasonal comparison.
How hot is Korea in July?
Average highs of 28 to 33 degrees with humidity of 70 to 80%. It feels hotter than the air temperature suggests. Urban heat island effects in Seoul can make the city feel 2 to 3 degrees hotter than the surrounding areas. The coast and Gangwon Province are somewhat cooler.
When does jangma (the rainy season) end?
Jangma typically ends between July 15 and July 25, with a transition to hot, sunny summer weather. The exact end date varies by year. After jangma ends, Korea typically has clear hot weather through August.
