Jamsil hit level 3 at 15:00 — the only district above the usual peak of 2. UV max reaches 7.15 today — use sun protection from late morning. TWD rose 0.5% vs KRW — Taiwan-dollar cash buys more won than yesterday.
How was Seoul yesterday?
Jamsil was the only area to reach level 3, at 15:00 — one step above the typical Seoul ceiling. Hongdae, Myeongdong and Seongsu each hit level 2 at 19:00, matching a normal evening. Gyeongbokgung peaked at level 1 at 11:00 and Bukchon at 0, both quieter than usual for summer. PM2.5 averaged 10.5 µg/m³, firmly in the good range. Temperatures ran 24–33°C, close to the seasonal norm.
What to expect today
The morning reads 22.5°C (feels 25) with no rain and PM2.5 at 10.4 µg/m³. UV max reaches 7.15, so plan sun protection for late morning. Clear skies hold until sunset at 19:30 — a good night for a palace or riverside walk. Tomorrow is clear again, 20.8–29.3°C with no rain.
Money check
The Taiwan dollar rose 0.5% against the won and the Chinese yuan 0.2%, so cash in those currencies gains a little buying power; the yen slipped 0.2%. The US dollar, euro and Hong Kong dollar held flat.
