What it feels like
Even in the same month, comfort often splits by “walking-heavy” versus “mostly indoors.”
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.
- • 🌧️ Main drivers: San Sebastián often runs on **drizzle/rain + wind + humidity**. Comfort is frequently about staying dry.
- • 🧥 Waterproof outer: umbrellas can struggle in wind. A hooded rain shell is high value.
- • 👟 Shoes: wet pavement is common. Consider water-resistant (or quick-drying) shoes with good traction.
Once you lock in a couple of constraints, the decision gets much easier.
