San Sebastián

La Concha has a composed, civic atmosphere, with swimmers, walkers and beach users sharing one of Europe's most recognisable seafronts. Ondarreta is calmer in character and closely associated with families, while Zurriola attracts surfers and a younger crowd. The Parte Vieja adds a lively contrast through compact streets and pintxos bars. This is not a Mediterranean resort promising constant heat or flat water. Atlantic weather is part of the experience, and cloud, clear light, rain and sunshine can pass through the same day. Visitors who accept that changeability gain a richer view of the city and its relationship with the sea.

Friday will be a mild day with temperatures rising from 17°C this morning to a high of 26°C by lunchtime, then cooling slightly heading into this evening. This morning brings clear skies and a light breeze from the east, making it pleasant for running, cycling, and tennis. As the afternoon develops, skies will become cloudy but remain dry with calm winds from the north. Heading into this evening, expect very cloudy skies with a light breeze from the south, continuing to make it pleasant for outdoor activities.

The beach offers small, knee-high waves around 0.9 meters, suitable for beginners and bodyboarders. Water temperature is a warm 23.4°C, ideal for swimming in just swimwear. Swimmers and paddleboarders can enjoy comfortable conditions. Surfers looking for bigger waves may need to seek alternative spots. Anyone taking a boat out should note that offshore waters are expected to be rougher with higher waves and potential storms.

This morning's light breeze from the east is ideal for runners and cyclists. The UV index will reach a peak of 6, indicating high UV levels. Strong sun protection is essential, with SPF 50+ sunscreen recommended, reapplied every 90 minutes. In the afternoon, the calm winds will allow for uninterrupted play for tennis enthusiasts and other outdoor sports.

Tomorrow will be cooler than today, with overcast skies and winds picking up from the west, reaching up to 14 km/h with occasional gusts. The day after will bring drizzle and stronger winds from the northwest, with gusts even higher.

San Sebastian is a refined Basque coastal city built around La Concha Bay, where pale sand, green hills and elegant streets meet the Cantabrian Sea. The city combines three very different beach experiences: La Concha in the centre, family-oriented Ondarreta to the west and the more exposed surfing beach of Zurriola to the east. Food and architecture matter as much as the sand.

La Concha Bay is framed by Monte Urgull, Monte Igueldo and Santa Clara island, creating the city's defining shape. The old port sits beneath Monte Urgull, linking modern leisure with San Sebastian's fishing and maritime history. Along the bay, late nineteenth- and early twentieth-century architecture reflects the period when the city became a fashionable royal resort. The distinctive white railings of the promenade, the city hall and the buildings of the central waterfront reinforce that formal character. These landmarks make the beach feel like part of the city rather than a separate attraction.

The central bay forms a near-perfect curve of sand beneath wooded hills and dense urban streets. Tides noticeably alter the width of the beaches, and the cooler Cantabrian water can carry swell even when the city looks calm. Zurriola's more open exposure demonstrates how quickly conditions change around the headlands. Green slopes give the coast a softer, wetter appearance than southern Spain, especially after rain. The best overview comes from walking the bay or gaining height on Monte Igueldo or Monte Urgull. Local flags, tide information and lifeguard advice should guide swimming plans, near exposed sections.
