Can you swim or snorkel in Menorca in January?
At 15.9°C our temperature-only guide describes the water as cold 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?
Use a full 3-5 mm wetsuit and keep the session within your cold-water experience.
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.
Menorca's coves can be calmer than Mallorca's open coasts. The water follows the western Mediterranean season: coolest in late winter, warmest in August.
