Trader consensus on Polymarket heavily favors mild highs of 17–19°C for Madrid on March 23, driven by the latest ECMWF and GFS ensemble forecasts clustering around 18°C amid a stable high-pressure ridge over the Iberian Peninsula. This setup promises ample sunshine and light southerly winds, boosting daytime heating after chilly nights typical of late March climatology, where historical averages hover near 17°C. Differentiation hinges on subtle model variances: ECMWF leans slightly cooler at 17–18°C due to potential mid-level clouds, while GFS hints at 19°C with clearer skies; AEMET's high-resolution runs will refine this in upcoming 12Z updates, amid a tight 2°C spread reflecting spring forecast uncertainty from variable boundary layer mixing.
