Plan around it
The forecast is only useful if it changes the plan. These are the Cozumel pages that match each kind of day.

The longer view
Today's forecast tells you what to wear. This tells you when to come.
Cozumel runs its warmest in summer (June – August), averaging 90°F by day and 78°F overnight. Winter (December – February) is the other end of it: highs around 82°F, lows near 70°F. That is a 20-degree spread between the hottest afternoon and the coldest night of a typical year, which is why the same packing list does not work twice here. Visitor numbers track it closely — winter is full, fall is quiet — so the cheapest weather is rarely the most comfortable weather.

Book around it
Departures cancel for weather, not for forecasts. Check the operator's own cancellation terms before you book on a marginal day.
These go through Viator and earn us a commission. You pay the same as booking direct, and the commission did not choose the list.
Per-seat pricing, fixed departure times, and other people on the boat. For one or two of you this is almost always the right call.
