Heading to San Diego? San Diego, USA, sits at 32.7°N in a subtropical climate zone. Before you lock in outdoor plans, compare how the three global models - European (ECMWF), American (GFS) and German (ICON) - forecast San Diego 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.
