Located on the shores of the Bay of Biscay, San Sebastián is subject to an oceanic climate that brings humidity and the occasional chilly breeze in the summertime. During the summer (June to August) months, tourists are booking flights to San Sebastián for a chance to lounge in the balmy weather, with temperatures resting around 70 degrees Fahrenheit, on average. Winters (December to February) in San Sebastián are mild and lows rarely dip below 45 degrees Fahrenheit; spring (March to May) and fall (September to November) are rainy seasons with temperatures on average sitting comfortably at 55 degrees Fahrenheit.
Whether you’re coming to town for the feast celebrating the city’s patron saint or you’re looking for a relaxing beach getaway, one thing’s for sure: Regardless of what you’re looking for in a vacation, San Sebastián is sure to deliver. With a temperate climate keeping the weather comfortable year-round, there’s no wrong time to book your flight to San Sebastián.
Peak Season:
Summer is the busiest time of year for booking San Sebastián flights, when the resorts are packed and the beaches attract visitors from Western Europe and the United Kingdom. If you plan on joining those who bask in the Basque country, try booking your flight to San Sebastián for the middle of August and take part in Semana Grande, a week-long festival with beachside performances and impressive fireworks displays.
Off-peak Season:
Cheap flights to San Sebastián are plentiful in the wintertime when bay breezes chill the shore and the beaches are bare. If you’re set on booking a cheap flight San Sebastián, make your travel arrangements for a late January visit: January 20 is the feast of San Sebastián. Join the fun as the Tamborrada festival hits the streets. The lively celebration is complete with midnight parades and mouthwatering banquets at the gourmet clubs, or sociedades gastronómicas, in town. If you’re looking to visit San Sebastián in the warmer weather, try booking your cheap flight to San Sebastián for late April or May: The spring rains are heaviest in the beginning of the season and the oncoming heat of summer make for pleasant conditions for beachcombing.
Walking is the best way to see San Sebastián. The city is compact and tourist attractions are close together, and you can always use one of San Sebastián’s efficient bus routes to get around. If you’re traveling to other Basque cities, or Barcelona and Madrid, you’ll find trains leaving from San Sebastián.
Don’t board your return flight without spending at least a day lying out on the shores of the Bay of Biscay. The most popular sandy stretches in San Sebastián are Playa de la Concha, Ondarreta, Zurriola and Fuenterrabia, a small fishing village just a few miles from San Sebastián and the French border.
For history buffs booking flights to San Sebastián, most of the notable monuments and historical points of interest can be covered in one day. Start with a walk along Paseo Nuevo and you’ll come to the Palacio de Minamar, famous for its immaculate courtyards and gardens. Spend some time perusing the galleries of the Museo Chillida-Leku, which is devoted to the work of Basque sculptor Eduardo Chillida, and then take a funicular to the top of Monte Igueldo or drive to the summit for breathtaking panoramic views of the city and the bay beneath you.
Before you book your flight to San Sebastián, check to see if your planned vacation coincides with one of the numerous festivals taking place throughout the year. The San Sebastián International Film Festival takes place every September, while the Jazz Festival, which is the longest continually running jazz festival in Europe, is scheduled annually for the last week of July. The Street Zinema Festival is an event not to be missed by those who booked their San Sebastián flights for the last week in August.
San Sebastián is located in the Basque Country of Spain, and though Castilian Spanish and English are widely spoken, picking up on a few phrases in Basque, or Euskara, before your flight are guaranteed help you out in a pinch:
–Hello: Kaixo
–Please: Mesedez
–Thank you: Eserrik asko
— Excuse me: Barkatu
— Do you speak English?: Inork ba al daki ingelesez?
