Weather tips for enjoying the ocean at Biscarrosse

To make the most of the ocean at Biscarrosse, it’s important to choose activities according to water temperature.

  • In summer, swimming, surfing and paddle-boarding are popular activities thanks to the warmer water.
  • In winter, more adventurous surfers can still enjoy the waves, but a full neoprene wetsuit is essential for protection from the cold.
  • In spring and autumn, an intermediate wetsuit is recommended to maintain a good body temperature during surfing or swimming sessions.

It’s important to note that ocean celsius is not static, and varies seasonally with sunshine, precipitation and gusts. On August 10, for example, it was between 20 and 25 degrees. Or 68 to 77°F. It decreases around March 1ᵉʳ (between 11° and 12°C). That’s why, if you’re a surfer, you need to adapt your arsenal to suit the season, for example putting on a shorty with 2 mm long sleeves. You can also use a wetsuit designed exclusively for spring. With a size of 32 mm. However, in March, you won’t be able to use it. Because of the falling sea temperature and cooler climate. You’ll need a 5/4 m or 5/3 mm wetsuit. Make sure you choose a very good quality one. Don’t forget your neoprene gloves and 3 mm boots. You’ll also need a hood in case of cold winds.

You can go to Arcachon. Arcachon is the ideal place for entertainment, restaurants, water sports and heritage. What’s more, the Biscarrosse lake is recommended for fans of water sports. On the lake, you can go sailing, boating and water skiing.
