consensus of the three models7-day forecast
where the models agree, and where they splitHeading to Grand Cayman? Grand Cayman, Cayman Islands, sits at 19.3°N in a tropical climate zone. It sits in the tropics, so it stays warm all year — the question on any trip is the wet season versus the dry season, not hot versus cold. Before you lock in outdoor plans, compare how the three global models — European (ECMWF), American (GFS) and German (ICON) — forecast Grand Cayman right now. Where they agree you can trust it; the days they split are exactly when a single weather app is least reliable. For a beach trip the rain and wind columns below matter most — that is what makes or breaks a day by the sea.
