Rain probability 88% today — keep a compact umbrella close. Crowd peaks hit level 3 in Myeongdong (14:00), Itaewon (02:00), Jamsil (14:00). TWD rose 1.2% vs KRW over the week; JPY, CNY, HKD slipped.
How was Seoul yesterday?
Peak levels reached 3 in Myeongdong, Itaewon, and Jamsil — the highest reading in the 24-hour window — and 2 in most other areas, with Hongdae and Yeouido at 1. Itaewon’s 02:00 peak is consistent with its nightlife pattern. PM average was 16 µg/m³, just over the ‘good’ threshold of 15 µg/m³. Temperatures ranged from 23.1°C to 26.8°C, roughly 2°C below the city’s late-August normals.
What to expect today
Rain is likely through the day (88% probability) with a narrow range of 23.1°C now and a UV max of 6.2 — if the sun peeks through, sunscreen still applies. Tomorrow clears with a high of 31.8°C, so plan for heat once the front passes. If rain breaks before sunset at 19:23, a palace or Han River walk is tonight’s move.
Money check
Over the past week, the Taiwanese dollar gained 1.2% against the won, so TWD cash now buys slightly more in Seoul; the yen (-0.8%), yuan (-0.2%), and Hong Kong dollar (-0.4%) lost ground, making their home currencies a touch weaker at the exchange desk. USD and EUR held flat.
