Seoul, South Korea

What it feels like
When mornings/evenings and indoor AC differ a lot, you feel the day’s length more than the number.
When it tends to fit
- • If you’ll walk a lot and you’re sensitive to wind or rain, cooler/drier conditions tend to fit better.
- • For photo-and-walk trips, sunny days usually matter more than the exact temperature.
- • If you want to keep fatigue low (kids/family trips), avoiding peak midday heat helps.
When it may not fit
- • If you struggle with humid heat, some seasons can feel tiring even when the numbers look similar.
- • In rainier periods, “walking as planned” can be harder—tight itineraries may not fit well.
What people usually wear
Not a single “correct outfit”—just common choices that cover most situations.
- • 🏙️ Baseline: Seoul has strong indoor heating/AC. The “outside vs inside” contrast can be more noticeable than the outdoor temperature. Thin layers help.
- • ❄️ Winter (-7 to 6°C feel): Puffer/thick coat + warm inner layers is common. Wind increases chill—scarf and gloves help.
- • 🌱 Spring (2–19°C): Mild afternoons with cool evenings. Trench/light coat with sweatshirts/shirts is common.
Once you lock in a couple of constraints, the decision gets much easier.
