San Sebastián Food Scene in December

May through October gives you the best weather and full restaurant schedules. Many top places close for vacation in November and February. But here's the insider tip: September is perfect. Summer crowds have thinned, but the weather stays warm enough for outdoor dining. July and August bring festival season. The International Jazz Festival in July fills the city with music and energy, but restaurants get slammed. August means locals flee for vacation, so some neighborhood bars close temporarily. Winter has its charms if you don't mind rain. Restaurant reservations become easier, and you'll experience the city like locals do. Plus, winter is mushroom season — Basque chefs go crazy for wild fungi from the nearby mountains.
