Can you swim or snorkel in La Gomera in January?
At 21.1°C our temperature-only guide describes the water as cool water. Comfort depends on your cold tolerance, immersion time and wind. A historical average cannot determine whether conditions are safe on any given day.
Do you need a wetsuit?

Which beach should you choose?
Look for a beach sheltered from the actual forecast waves and wind on your visit. Exposure, currents and entry conditions vary even where water temperatures are similar. Follow local warnings.
The Canary Islands sit in the Atlantic. Water is usually milder year-round than the western Mediterranean, but trade winds and coast orientation change how it feels. Check the beach forecast, not only this island average.
