Biarritz sits on France's southwestern Atlantic coast, where Basque culture, Belle Époque architecture, and serious surf breaks converge just a few kilometers from the Spanish border. This former whaling village turned 19th-century royal playground still carries both of those identities: you'll find ornate seafront palaces like the Hôtel du Palais steps from wetsuit-clad surfers catching waves at Côte des Basques. The food scene leans heavily Basque, from the covered Les Halles market with its cheese vendors and morning cafés to seafood-driven spots along the tiny Port des Pêcheurs, and the region's deep chocolate-making tradition means artisan chocolatiers are everywhere you turn.
Your ideal window for Biarritz runs from late April through early November, with the sweet spot falling in summer (June through August) when beach days are reliable, surf conditions peak, and the city's festival calendar is at its fullest. Expect the Fête de la Musique filling the streets with live performances around the summer solstice, surf competitions on the Grande Plage, classical piano concerts in late July and early August, and pelote basque matches on warm evenings. If you'd rather dodge the peak summer crowds and slightly higher accommodation costs, September and October make a compelling secondary window: the weather remains comfortable, the renowned Le Temps d'Aimer dance festival takes over the city in September, and you'll have the beaches and coastal paths with more breathing room.
Spring in Biarritz City Centre, France
Biarritz wakes up gradually in spring. March can still feel brisk, with morning lows around 47.5°F (8.6°C), but the coastal promenade from the lighthouse past Rocher de la Vierge to Côte des Basques is gorgeous without summer crowds. Showers pop up roughly one to two days per month through the season, so a compact rain jacket earns its suitcase space. This is a fine time to explore the covered Les Halles market at a leisurely pace, picking up local cheese and Basque charcuterie for a picnic lunch overlooking the ocean.
By May, afternoons warm to highs near 63.5°F (17.5°C), and the lengthening days (sunset doesn't come until well past 9pm) give you plenty of evening light for strolling through Port des Pêcheurs or climbing the lighthouse for panoramic views. Tourism picks up noticeably in May but stays well below summer levels, so accommodation deals are still common. The nearby town of Bayonne typically hosts its ham fair around the Easter holiday period, a celebration of the region's famous cured ham that's an easy side trip.
Surfers will find the Atlantic already delivering solid swells, and the water is quiet enough that beginners can book lessons at the surf schools along Côte des Basques without competing for wave space. Pack layers: mornings and evenings stay cool, and an ocean breeze can make short sleeves feel optimistic before midday.
Summer in Biarritz City Centre, France
Summer is when Biarritz fully comes alive. The Grande Plage fills with sunbathers and surfers, the Art Deco Casino Barrière opens its terrace to warm evenings, and the city's calendar overflows with events. Around the summer solstice in late June, the Fête de la Musique transforms streets and rooftops into stages for live performances of every genre. Wheels and Waves, a celebration of motorcycle culture and surf, typically rolls through in June as well. Highs average 75.4°F (24.1°C), warm enough for full beach days but noticeably milder than the Mediterranean coast, so you're comfortable walking the promenade even at midday.
July brings Bastille Day festivities in mid-month, surf competitions along the coast, pelote basque matches at the outdoor frontons on summer evenings, and a classical piano festival that runs from late July into early August with concerts at venues like the Espace Bellevue and Casino salons. Early August is the warmest stretch, when highs reach 78.7°F (25.9°C) and overnight lows stay mild at 61.5°F (16.4°C). Rain is at its scarcest: you can expect roughly one wet day per month across the whole season, leaving long stretches of dry weather for the beach. The sun lingers past 9:30pm in June and July, so dinner reservations at 8pm still feel like the middle of the afternoon.
This is peak tourist season, and accommodation prices climb accordingly. Book early, especially for July and August. The seafood at the restaurants along Port des Pêcheurs is worth the splurge, with Basque-influenced dishes and tapas served in the colorful fishermen's huts overlooking the tiny harbor. Lows average 59.7°F (15.4°C), so keep a light sweater handy for breezy evenings on the terrace.
Fall in Biarritz City Centre, France
September kicks off with one of Biarritz's cultural highlights: Le Temps d'Aimer la Danse, a dance festival running for over thirty years that stages performances across the city's theaters, beaches, and public squares over roughly ten days. The programming spans ballet, contemporary, hip-hop, flamenco, and Basque dance traditions, with many outdoor shows free to attend. Highs of 68°F (20°C) make for comfortable walking between venues, and the summer crowds have thinned considerably.
October is one of the quieter months yet still pleasant enough for coast walks and surfing. Precipitation picks up as fall progresses, reaching roughly three to five wet days per month, so waterproof layers become essential gear. Lows settle around 51.1°F (10.6°C) by the season's midpoint, and mornings carry a genuine chill. Early November brings All Saints' Day, when many French families travel and some shops may close briefly. November is also one of the rainiest stretches of the year, so plan indoor diversions: the Aquarium opposite Rocher de la Vierge, the Cité de l'Océan museum, or the chocolate shops like Henriet that have been crafting sweets in the region for decades. From late November, the Biarritz en Lumières festival begins transforming parts of the city with light installations: trees in the public garden glow with illuminated displays, and the facades of the Casino and Mairie are bathed in shifting colors.
Accommodation rates sit slightly above average in September when the festival draws visitors, then drop through October and November. A day trip to nearby Saint-Jean-de-Luz or across the border to San Sebastián is easy to arrange and rewards you with even more Basque coastal scenery and gastronomy. Pack a warm fleece and a rain shell for late-season visits.
Winter in Biarritz City Centre, France
Winter strips Biarritz back to its quieter, local character. The surf crowd thins to dedicated year-rounders in wetsuits braving the cold Atlantic, and the grand seafront hotels feel more contemplative than celebratory. Highs of 55°F (12.8°C) and lows of 40°F (4.4°C) make beach lounging unlikely, but the coastal promenade is striking in its winter drama, with Atlantic storms sending spray over the rocks at Rocher de la Vierge. Rain falls regularly, roughly three to five days each month, so plan for wet weather.
The Biarritz en Lumières festival, which begins in late November, continues through mid-January with light installations across the city, making evening strolls especially atmospheric. Daylight is short, with barely nine hours in December, so morning starts feel slow and evenings come fast. The Christmas and New Year's holiday period brings some life back to the streets, though this remains Biarritz's quietest season by far, with February seeing the lowest visitor numbers of the year.
The upside is solitude and authenticity. Les Halles market runs every morning year-round, and you'll share the stalls with locals rather than tourists. Chocolatiers and pâtisseries feel especially inviting when the ocean wind is biting. Pack warm layers, a waterproof coat, and sturdy shoes for the slippery coastal paths.

Travel Tips & Safety for Biarritz City Centre, France
Biarritz has its own small airport with connections to several French and European cities, and the Gare de Biarritz train station sits about three kilometers from the city center with a quick bus or taxi ride into town. Most of the main attractions line the coastal promenade and are easily walkable, though parking is tight near the lighthouse and beaches if you're driving. A basic level of French goes a long way here; English is spoken in tourist-facing businesses, but a few words in French (or even Basque) will earn genuine warmth from locals.
Biarritz is generally very safe for visitors. The main practical concern is ocean safety: Atlantic currents and swells can be powerful, especially at Côte des Basques during tide changes, so always swim at lifeguard-patrolled beaches and heed posted flags. Keep standard precautions with your belongings in crowded beach areas during peak summer. If you're driving the coastal roads toward Spain or into the Basque interior, be aware that mountain roads can be narrow and winding.
