What to wear in July
Rainy season meets heat. Breathability, sweat-wicking and rain-readiness matter.
July is where the rainy season meets the heat. Humidity peaks for the year, and late in the month heatwaves and tropical nights arrive. The same temperature feels far hotter when damp, so breathability and sweat management are everything.
Thin, loose linen or functional fabrics that don't cling keep you coolest. With frequent rain, quick-dry fabrics, water-friendly shoes and an umbrella are essential; strong indoor A/C means one thin layer is worth carrying.
Seoul averages 23°C at night and 30°C by day. A low of 23 means it does not cool down after dark, and tropical nights push that number higher late in the month. Whichever hour you dress for, the answer comes out the same.
