Can you swim or snorkel in Cozumel in February?

At 27.2°C our temperature-only guide describes the water as warm 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?

Most people are comfortable in swimwear or a light rash guard.

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.

Cozumel sits on the Mesoamerican Reef. Water stays warm year-round, but winter months are a few degrees cooler than late spring. Use the month sections below for typical averages, then check today's forecast before a drift snorkel.
