Pornichet - Bonne Source
France
Pornichet
Pornichet – Bonne Source is a spot appreciated by local riders for its perfect balance between accessibility and wind quality. Located at the eastern end of La Baule bay, it benefits from a more consistent wind and a calmer environment. Bonne Source beach stretches for several kilometers with a sandy bottom and a large launch area. The atmosphere is relaxed, away from the crowds of the big bay, but the conditions are just as conducive to great freeride sessions. It is a versatile, safe, and very pleasant spot all year round.
The wind data shown here comes from ERA5 (via Open-Meteo) over 4 years, reprocessed to reflect realistic conditions.
👉 Average wind has been calibrated to avoid the usual underestimation of models.
👉 Gusts have been corrected by a median ratio to avoid unrealistic extreme values.
👉 Each day is summarized by the median wind (P50) observed during useful hours (8am–8pm), then classified into wind ranges.
👉 The weighted mode mixes average wind and gusts to best reflect felt wind.
- 🟢 10–16 kts: light but sailable wind (especially on foil).
- 🟡 16–22 kts: ideal range, comfortable conditions for most.
- 🔴 22–28 kts: strong wind, reserved for experienced riders.
- 🟣 28+ kts: extreme conditions, committed riding.

flatBonne Source offers a flat water surface at low tide and regular choppy at high tide. The dominant wind from west to southwest blows side-onshore and remains stable. At high tide, the water surface becomes livelier but remains perfectly navigable. The launch is easy, the sandy bottom and the very wide beach at low tide make maneuvers simple and safe. It is a perfect spot for freeride, big air, or long rides along the shore. In summer, the local thermal can enhance the west breeze in the late afternoon.
Wind from west to southwest, side-onshore, between 15 and 25 knots. This is the most stable and comfortable direction for smooth sailing along the entire beach.
At low tide, the water surface is flat and smooth, ideal for freestyle or learning. At high tide, it becomes choppy with small spaced waves. The bottom is entirely sandy, with no rocks or annoying seaweed. On days with strong west winds, small ramps perfect for jumping appear near the shore.
Weak to moderate currents depending on the tide. At high tide, a slight drift towards La Baule can be felt, with no major danger. The water surface remains generally stable and clear.
Riders mainly use 8 to 12 m². In summer, a 10 or 11 m² is usually sufficient. In winter, 7 to 9 m² for more powerful sessions.
The dominant wind is from the west and southwest, between 12 and 25 knots. Afternoon sessions are often enhanced by a local thermal effect. In winter, depressions bring strong (25 to 35 knots) but irregular winds. The full west exposure ensures a constant and safe wind across the area.
Moderate and windy oceanic climate. Temperatures range between 8°C and 26°C depending on the season. Winters are humid but rarely cold, and summers are tempered by sea breezes. The spot works well from March to October, with excellent consistency in spring and autumn.
Between 0.5 and 2.5 meters depending on the tide. Sandy bottom, gentle and safe slope.
Between 10°C and 20°C depending on the season. A 5/4 mm full suit in winter, 3/2 mm or shorty from April to October.
