How warm water works

Sea temperature lags the air by a month or two, so the warmest water comes in late summer and the coolest in late winter. A beach counts as warm water when at least six months average 24 C (75 F) or more, which is warm enough to swim without a wetsuit.

How we verify warm water

Scored from monthly sea surface temperature over the last three years of marine model data. Counts as warm when at least six months average 75 F (24 C) or more. Sources and methodology
