What to expect today

Now: 22.9°C (feels 26.2°C), rain probability 63%, PM2.5 9.5 µg/m³. UV max is 7 — use sun protection in sunny gaps. Tomorrow (Sat) is code 51 light rain, 78% probability, 23.3–29.3°C. Dated action: keep an umbrella ready until the rain window passes; if it clears, sunset at 19:26 still allows a palace or Han River visit tonight.
