Is San Sebastian worth it this weekend?
Weather watch
Treat the numbers as the story for San Sebastian: temperature band and rain risk, then decide if the trip is on.
San Sebastian, Basque Country
Weekend air in San Sebastian sits near 67°F / 61°F, plus only light rain on the books (~0.25 in) — enough to decide whether the trip is on.
What matters isn’t whether San Sebastian is famous — it’s whether 2026-08-22 – 2026-08-23 supports the outdoor time you want (sit-outside terrace weather).
If the numbers still look good by Friday, lock the plan around 67°F — not a vague “nice weather somewhere.”
