What it feels like
When mornings/evenings and indoor AC differ a lot, you feel the day’s length more than the number.
Rain changes how you move, and wind makes the same temperature feel much harsher.
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.
- • 🌡️ 2–10°C feel (winter): Coat/padded jacket + thermal layers are common. If you add Miyajima or riverside exposure, wind can drop comfort quickly—scarves help.
- • 🌡️ 10–18°C (early spring / late autumn): Trench or light coat + sweatshirt/shirt works well. Days can feel mild; evenings can be breezy.
- • 🌡️ 18–25°C (spring / autumn): Short or long sleeves with a thin outer layer is usually enough. Walking comfort matters because step counts rise easily.
The same numbers can still feel different depending on how you travel.
