San Sebastián
La Concha bay is the most beautiful urban beach in Europe. Basque pintxos in the old town, three Michelin three-stars within 30 minutes by car, and Atlantic-tempered weather that escapes the worst of the Spanish heatwave summer.
Mostly sunny with the odd cloud. Real holiday weather.
Days 1–5 are usually reliable, 6–10 drift, 11–14 are the model guessing. Check again the day before you fly — more on what this can and can't do.
When to go
From the 2026 climate study, not the live forecast.The Basque coast escapes the Iberian peninsula's mid-summer heat — peak August is 25°C in San Sebastián while Seville is 42°C. Sea climbs from 17°C in May to 22°C in late August. Best July through September; June and October are mild and quiet. The pintxo culture runs year-round.
