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.
- • If you do many night outings, evening wind and chill can matter more than daytime highs.
What people usually wear
Not a single “correct outfit”—just common choices that cover most situations.
- • 🌬️ Baseline: Jeju is wind-shaped. Wind + wetness can drop perceived comfort sharply, especially in winter and spring.
- • ⛰️ Hallasan elevation: Mountain conditions can feel completely different from the city. If you plan Hallasan, carry one warmer layer than downtown suggests.
- • ❄️ Winter (2–12°C feel): Wind-resistant coat/puffer with warm layers is common. Rain happens—waterproofing helps.
Once you lock in a couple of constraints, the decision gets much easier.
