Season planner for Cozumel
Diving is viable year-round. March to June often brings the calmest seas. Winter delivers cooler water around 26°C and the chance to see spotted eagle rays at northern sites, but periodic "Nortes" can close the port. Peak hurricane risk is Aug to Oct. Water typically ranges 26°C to 29°C with trade winds around 20.0 kph to 28.0 kph.
