What it feels like
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.
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: Siena is a hill city in inland Tuscany, so evenings can cool down quickly. It’s common to need a different comfort level at noon vs after sunset.
- • ☀️ Summer (Jun–Aug): Strong sun and hot midday. Breathable/quick-dry clothing plus hat/sunscreen/water (electrolytes) helps.
- • 🌬️ Evening breeze: Even if days are T-shirt weather, evenings can feel cooler—bring a thin shirt/cardigan.
Once you lock in a couple of constraints, the decision gets much easier.
