Latest ensemble forecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF) and U.S. Global Forecast System (GFS) show a tight clustering around peak afternoon temperatures of 16–18°C in Madrid on March 26, driving trader consensus toward 17°C at 46.5% implied probability and 16°C at 25.5%. This positioning stems from a recent cold front sweeping across the Iberian Peninsula over the past 48 hours, ushering in cooler, drier continental air that has tempered earlier mild spring conditions, with observed highs dropping from 20°C+ mid-week to 15–17°C yesterday per AEMET observations at Madrid-Barajas Airport. Climatological March norms hover near 16°C, reinforced by stable upper-level ridging limiting convective activity. New model runs expected overnight may adjust for any subtle boundary layer warming, but current low spread underscores high confidence in these leading outcomes.
