where the models agree, and where they split

Heading to USA? USA, USA, sits at 34.1°N in a subtropical climate zone. The averages on this page are measured at Los Angeles, the main gateway for AU 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 USA 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 city break, the rain hours below tell you which days to plan indoors.
