When to go
Isla Mujeres is a year-round destination, but your experience changes with wind and storm patterns.
Best overall window
Drier weather, breezy evenings, and comfortable water around 24°C to 26°C.
Outside that window
Peak heat plus higher storm and hurricane disruption risk. Watch forecasts and keep schedules flexible.
Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
The overall row stays visible so you can compare it against the currently selected scope.
