Tips for Diving in the Cantabrian Sea
- Proper wetsuit: Water temperatures range from about 12 °C in winter to 20–22 °C in late summer. A semi-dry or dry suit makes the dive much more comfortable.
- Check sea conditions: swell affects dive operations.
- Wear a hood and gloves outside of summer.
- Plan your air consumption carefully: you’ll use a bit more in cold water.
