Trader consensus on Polymarket heavily favors a high of 13°C (32%) for Madrid on March 29, driven by the latest European Centre for Medium-Range Weather Forecasts (ECMWF) and U.S. Global Forecast System (GFS) model runs showing a cool air mass from northern Europe suppressing temperatures amid cloudy skies and light precipitation risks. AEMET, Spain's national meteorological agency, aligns with this outlook, projecting daytime highs of 12–14°C based on current upper-air patterns and soil moisture from recent rains. Historical late-March averages hover around 16°C, but climatological analogs to similar pressure setups suggest 2–4°C below normal. Uncertainty stems from potential ridging that could boost 15°C+ (11% combined) or lingering clouds capping below 12°C (30% combined); watch AEMET's 12Z update tomorrow for refined guidance as the event nears resolution.
