Traveller notes on Isla Mujeres in April
Other months in Isla Mujeres
Isla Mujeres's forum calls March the best time of year weather-wise — sunny and hot with pleasant nights, though rainfall stays low rather than absent. Regulars flag March as typically the windiest month locally, and note a passing cold front can still knock a few degrees off the temperature, so a light wrap for the evening is worth having.
