When to go
Little Cayman is diveable yearround, but the easiest allaround trip window is December to April, when the Cayman Islands are in their drier, cooler season and beach days are more comfortable.
Best overall window
Dryseason planning, cooler breezes, generally calmer beach days, and comfortable 26°C to 28°C water.
Outside that window
Hottest and wettest stretch, with 29°C to 30°C water, higher humidity, and tropicalsystem monitoring.
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.
