How was Seoul yesterday?
Crowd peaks reached level 3 only at Itaewon (15:00) and Jamsil (18:00); Hongdae, Myeongdong, Seongsu, Gyeongbokgung, Bukchon, and Yeouido maxed at level 2 between 11:00 and 20:00 — steady but not extreme for mid-August. Hongdae’s camera average of 2.4 suggests a typical, walkable evening. PM2.5 averaged 9.5 µg/m³, well inside Seoul’s “good” range. Temperatures ranged 20.0–29.7°C, a normal late-summer spread with no heat stress.
What to expect today
It is 21.7°C now (feels 24.8°C) with a 51% rain chance, so carry a compact umbrella. UV max hits 6.65 — use sunscreen even under clouds. Tomorrow turns wetter: 22.7–28.9°C and 65% rain. If it stays dry until sunset at 19:28, a palace or river walk tonight is the move.
