Hossegor or Biarritz? How to choose your spot based on the conditions of the day

Before talking about conditions, you need to understand who you're dealing with. These two spots are not interchangeable. They each have their own distinct personality.

Hossegor, La Gravière is the most feared and respected spot on the Basque coast. A sandbar that changes shape after every big swell, capable of producing short, powerful tubes that close out in seconds. The wave is hollow, fast, and physical. It punishes mistakes and rewards technical surfers. This is not a spot for beginners, it's a competition spot: the WCT (World Surf League Championship Tour) is held there every October. During the season, the crowds are large, the levels are high, and the atmosphere in the water is tense. This spot forces you to earn your wave.

Biarritz, La Côte des Basques is a completely different story. A long beach facing southwest, with gentler, more regular, longer waves. It's the most democratic surf beach in the Basque Country, where all generations coexist, surf schools set up shop, and beginners can progress without getting wiped out. It gets crowded in summer, yes, but it's less aggressive in the water. The average level is more mixed, which changes the atmosphere of the session.

Hossegor is selective, Biarritz is welcoming. Both are excellent, but not for the same conditions or the same surfers.

This is the heart of the article. Here is the complete decision grid. No feelings, no bias, just the conditions and their concrete translation on each spot.

This table shows the logic that Swellr integrates directly into the app. Rather than giving you raw figures such as height, period, and direction, the app cross-references all these variables with your profile and gives you a personalized spot recommendation. You no longer have to do the math yourself. The grid runs in the background, and in 10 seconds you'll know whether Hossegor or Biarritz is waiting for you this morning.

One key point that is often overlooked in this table is the period. A 1.5m swell with a 7-second period means chaos in Hossegor, as the waves don't have the power to form hollow barrels. The same height with a 14-second period is a completely different story: organized waves, concentrated energy, potential tubes. Period changes everything, and it's often the variable that surfers underestimate.

Hossegor doesn't give anything away for free. But when conditions align, it's one of the best beach breaks in Europe. Period.

The ideal conditions to aim for:

• Height: 1.2 to 2.5 meters
• Period: greater than 11 seconds. Below that, the wave lacks momentum.
• Direction: W to NW-W, which feeds directly into La Gravière
• Wind: NE offshore, light to moderate. It keeps the wave clean and produces pitched lips.
• Tide: mid-ebb to low. This is when the sandbars are at their deepest.

The perfect window looks like this:

October. The day before, a low-pressure system crossed the Atlantic. This morning: ground swell 1.8m / 14s, direction NW-W, NE wind 15 km/h, falling tide. Sunrise at 7:47 a.m. You're in the water at 7:30 a.m. For 90 minutes, you surf the best waves of the year.

When to avoid it:

• If you're a beginner: always. Without exception. The rip current, the power of the waves and the density of the water make this a dangerous spot for those who are not sufficiently skilled.
• Swell less than 1 m: the waves don't have enough energy for the sandbars at Hossegor, you'll get bored.
• Strong onshore wind: the waves become soft and broken, and it's not worth the effort.
• August after 9 a.m.: the spot looks like a floating parking lot. Even if the conditions are good, the crowds ruin the session.

The bonus spot: if Hossegor is too crowded or too big, check out La Nord d'Hossegor, a few hundred meters to the north. The spot is more protected, slightly less exposed to direct swell, and often less crowded. Perfect when La Gravière is beyond your abilities for the day. Be honest with yourself.

Biarritz deserves better than its reputation as a tourist spot. Yes, it gets crowded in summer. Yes, the average level is lower. But in the right conditions, La Côte des Basques offers excellent surfing. It remains accessible when Hossegor is impracticable.

Ideal conditions:

• Height: 0.5 to 1.5 m. The beach transforms with good small swells.
• Period: all periods work, but from 10s it's much better.
• Direction: SW to W, the beach's exposure is perfect for these directions.
• Wind: E to NE offshore. Even a light breeze is enough to smooth out the waves.

The perfect window in Biarritz:

Spring. SW swell 1 m / 10 s. Clear skies, sun from 8 a.m. Light NE wind, 10 km/h. Mid-rising tide. The waves are clean, regular, and long. You can ride wave after wave and work on your turns. No one steals your waves. It's pure, unadulterated fun.

When to avoid it:

• Low tide on the north side: rocks are exposed, dangerous area at this tide.
• Large swells over 2m: The Côte des Basques closes, the waves break in a brutal shore break. It is no longer enjoyable to surf.
• July and August between 10 a.m. and 5 p.m.: the beach becomes impractical for surfing. Too many swimmers, too many boards, too much tension. If you want to surf in Biarritz in the summer, do it before 9 a.m. or after 6 p.m.

Alternative spots in the area: if La Côte des Basques is packed or closed, there are two reliable options:

• Anglet, Les Cavaliers: a few kilometers north, a quality beach break, slightly more exposed to the NW swell. Less known to tourists.
• Bidart, Ilbarritz: south of Biarritz, more intimate, waves often cleaner in average conditions. A well-kept secret among locals.

Let's stop beating around the bush. Here's the straightforward decision based on your profile:

• Beginner (less than one year of surfing) → Biarritz, always. No question. If you don't yet have a solid foundation in paddling and wave reading, Hossegor is not an option, it's a risk. In Biarritz, enroll in a surf school if you can: you'll progress twice as fast with instruction.
• Intermediate (1 to 3 years of surfing) → Biarritz by default, especially outside of special conditions. You can start considering Hossegor when three criteria are met: swell between 0.8 and 1.5 m, period greater than 10 seconds, offshore wind. Outside of that, Biarritz will give you a better session.
• Advanced (3+ years, comfortable on solid waves) → Hossegor as soon as the conditions are right. Biarritz is still a good option for fun sessions or days when you want to surf without pressure. But if the swell is clean and the period is long, you know where you need to be.
• Looking for the session of your life → Hossegor, in October, after an Atlantic storm, at sunrise. Period. There is no other answer.

Be honest with yourself about your level. It's the most important factor, more than the tide, more than the direction of the swell. A good surfer at an average spot will have more fun than an overwhelmed surfer at a good spot.

No matter which spot you choose, there is one rule that never changes: the best sessions are early in the morning.

In summer, the wind shifts onshore between 11 a.m. and 12 p.m. along almost the entire Basque coast. This west to southwest wind destroys the quality of the waves, making them soft, disorganized, and less powerful. A session at 2 p.m. on decent swell is often ruined by the wind.

The crowds follow the same schedule. On weekends, the parking lots in Hossegor and Biarritz start to fill up as early as 8:30-9 a.m. In the water, the line-up quickly becomes crowded, sometimes aggressive, and always less enjoyable. The effort/quality ratio plummets.

The golden rule: be in the water between 7 a.m. and 10 a.m. These three hours, especially the first two after sunrise, often offer the best conditions of the day: no wind or offshore wind, clean waves, few people in the water.

During the week, off-season (October to April), this advantage is multiplied. You can arrive at 9 a.m. for a weekday session in Hossegor and find an empty line-up. This luxury disappears completely in July and August.

Hossegor and Biarritz are two spots, two characters, two audiences. One selects and rewards experienced surfers when the swell is right. The other welcomes everyone and offers quality sessions in more accessible conditions. Both deserve respect, and both will disappoint you if you go there in the wrong conditions or with the wrong level.

Remember this: the best spot is the one that matches your level and the conditions of the day. Not necessarily the most famous one. Hossegor is legendary. But a smooth session in Biarritz is better than a difficult session at La Gravière where you get ridiculised by the waves.

Swellr does exactly that for you: it cross-references your local conditions in real time with your surfer profile to point you to the right spot at the right time. No more mental calculations at 6:30 a.m. No more guessing about the weather. Just a clear, data-driven recommendation so you can maximize every session.
