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.
