Best months to get married
San Sebastian - Donostia in Basque - is regularly named among the most beautiful cities in Europe, and it is hard to argue. La Concha bay curves between two wooded hills like a perfect crescent, the Belle Epoque architecture lines the promenade, and the old quarter behind is packed with the most extraordinary concentration of Michelin-starred restaurants and pintxos bars on the planet. Couples who choose San Sebastian are choosing one of the world great cities for food, beauty, and atmosphere - they are just also choosing Atlantic weather.
The best months for a wedding in San Sebastian are July and August. July averages 22 degrees C with just 7 rainy days - the driest month of the year. August is warmer at 23 degrees C and similarly dry. These are the two months when the city is at its most vibrant: La Concha beach is full of life, the evening light over the bay is extraordinary, and the combination of warm days and long Basque evenings creates a setting that is genuinely hard to replicate anywhere else.
June is also a strong option at 20 degrees C, with similar rainfall to July. The city is slightly quieter before the summer peak and the views from Monte Igueldo and Monte Urgull are exceptionally clear in June when Atlantic mists have not yet settled in for the season. For couples willing to plan around the weather rather than expect guarantees, June through September offers San Sebastian at its finest.
The honest picture: San Sebastian is one of the rainiest cities in Spain. It receives around 150 rainy days per year - the Atlantic coast is genuinely wet compared to the Mediterranean. July and August are the exceptions, but even in these months a rainy day is possible. Couples who choose San Sebastian embrace this rather than fight it. The best venues here - clifftop hotels, converted palaces on the river Urumea, the grand casino on La Concha - all have excellent indoor spaces that make rain irrelevant.
Spring in San Sebastian (April and May) brings mild temperatures of 14-17 degrees C and considerable rainfall. The city is beautiful in the green, misty atmosphere of Basque spring, but outdoor ceremonies require flexibility. May in particular can be lovely when clear - the bay is calm, the hills are vivid green, and the city has a quiet intimacy before summer arrives. Some couples specifically choose May for the lower costs and the feeling of having the city to themselves.
The San Sebastian International Film Festival in September is one of Europe great cultural events - if your wedding falls during festival week (usually mid-September), expect accommodation to be scarce and expensive, and the city to be buzzing with an energy that may work beautifully for a wedding atmosphere. For American guests, the festival connection and the culinary reputation of San Sebastian make it one of the most compelling destination wedding cities in Europe - a place people will genuinely travel for, not just attend out of obligation.
Frequently Asked Questions

The best months for a wedding in San Sebastian are July and August. July averages 22 degrees C with just 7 rainy days - the driest and one of the warmest months of the year. August reaches 23 degrees C with similar low rainfall. These months offer the best combination of warm weather, long evenings, and the city at its most vibrant, with La Concha bay alive with activity.
Is September a good month for a wedding in San Sebastian?
September is a reasonable choice for a wedding in San Sebastian - temperatures average 21 degrees C and rainfall begins to increase again after the dry summer (around 9 rainy days). The San Sebastian Film Festival in mid-September brings exceptional energy to the city but reduces hotel availability significantly. Early September (before the festival) can be excellent, with summer warmth still lingering and the city noticeably quieter.
What is the weather like in San Sebastian for weddings?
San Sebastian has a mild Atlantic climate - temperatures never get extremely hot or cold, but it rains considerably more than Mediterranean Spain. July and August are the driest months with 7-8 rainy days. The rest of the year sees 11-14 rainy days per month. Summer temperatures stay around 22-23 degrees C. Couples choosing San Sebastian do so for its extraordinary beauty and culture, understanding that weather flexibility is part of the deal.
Does it rain a lot in San Sebastian in summer?
Summer is the driest season in San Sebastian, but it is still wetter than anywhere in Mediterranean Spain. July averages just 7 rainy days - the driest month - and August is similar. Rain in Basque Country tends to come as short Atlantic showers rather than sustained downpours, and summers often have long clear stretches of beautiful weather. A covered terrace or good indoor backup makes outdoor summer weddings very manageable.
Why do couples choose San Sebastian for a destination wedding?
San Sebastian consistently ranks as one of the world best food cities - it has more Michelin stars per capita than almost anywhere on earth, and the pintxos bar culture of the old quarter is unmatched. Add the crescent of La Concha beach, the Belle Epoque architecture, the film festival prestige, and the Basque cultural identity, and you have a city that gives guests a genuinely extraordinary experience. Couples choose it because their guests will never forget it.
