Can you swim or snorkel in Cancun in February?
At 26.7°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.
Cancun's hotel zone sits on the same warm Caribbean as Isla Mujeres and Puerto Morelos, but lagoon and beach water can run murkier. Use this page for temperature, then open the reef forecasts for wind, waves and a snorkel score. Temperature is not a safety rating.
