where the models agree, and where they split

Heading to Costa Rica? Costa Rica, Costa Rica, sits at 10.3°N in a tropical climate zone. The averages on this page are measured at Guanacaste (Tamarindo), the main gateway for CA travellers; inland and mountain areas run cooler. Before you lock in outdoor plans, compare how the three global models - European (ECMWF), American (GFS) and German (ICON) - forecast Costa Rica 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.
