La Nord - surf spot statistics

Best Surf Season (October - March)

The North Atlantic delivers its most potent energy to the shores of La Nord during these months. As the polar jet stream strengthens and extratropical cyclones deepen south of Iceland, a relentless procession of powerful, long-period swell pulses toward the French coastline. Average wave heights consistently eclipse the 1.5m mark, often reaching 1.8m, with periods rarely dropping below 12 seconds. The dominant swell angles from the WNW and NW align perfectly with the west-facing beach, producing heavy, pitching waves at the many reefs and sandbars. Ideal offshore winds from the WNW, W, WSW, and SW quadrants are common, especially during high-pressure ridging after frontal passages, resulting in clean, glassy conditions for an average of 35-40% of the time. This is the prime window for serious surf.

Fair Surf Season (April & September)

These transitional shoulder months offer a mixed bag. March's lingering winter energy gives way to a more variable pattern in April, with average swell height dropping to 1.2m and periods shortening to 11 seconds. September sees a renewed pulse as autumn cools the Atlantic, bringing back 1.1m averages and 10.6s periods. While still capable of delivering fun, rippable surf with the occasional solid groundswell, the consistency and power of winter are missing. Wind patterns become less reliable, with ideal conditions occurring only 25-38% of the time. However, when a high-pressure system settles over the Bay of Biscay, the combination of glassy offshore winds and a moderate NW swell can produce some of the most enjoyable sessions of the year, with smaller crowds.

Low Surf Season (May - August)

The summer months are characterized by a dramatic lull in surf energy. Average swell heights hover around just 0.9m, and periods are a short 9-10 seconds, typical of local windswell and distant, weak groundswell. The swell direction is overwhelmingly from the NW (50-67% of the time), which while still optimal for the spot, lacks the size and punch due to the absence of strong Atlantic storms. The trade-off is that winds are often from the west and northwest (onshore), creating choppy, messy conditions. The ideal wind percentage drops to its annual low of 16-21%. This is a time for groveling on small-wave equipment, and most local surfers take a break or chase the rare tropical swell.

October: The Renaissance Begins

October marks a clear return to quality winter conditions. The average swell jumps to 1.3m with a period of 11.3 seconds, and energy continues to build throughout the month. The swell rose shows a healthy split between NW (42.1%) and WNW (41.2%) swells, providing both power and variety. Heights regularly hit the 1-2m range (over 23% of WNW swells are 1-1.5m and over 9% are 1.5-2m). The wind is ideal 35% of the time, with offshore breezes from the SW, WSW, W, and WNW quadrants becoming more frequent as high-pressure systems settle over Europe. The jet stream is strengthening, and the first strong lows of the season are already spinning. This is the time to watch the charts closely: the right combination of a 10-14s period NW swell and offshore wind will deliver some of the best, most powerful waves of the year.
