Trader consensus on Polymarket heavily favors mild highs of 18-20°C for Madrid on March 23, with 26% odds on 18°C edging out 19°C at 23.5%, driven by the latest AEMET and ECMWF ensemble forecasts converging on 18.5-19.5°C peaks amid a persistent high-pressure ridge over Iberia. This setup, fueled by southerly flows advecting warmer Atlantic air, marks a 3-4°C departure above the March historical average of ~16°C at Madrid-Barajas. Differentiating factors include boundary-layer mixing efficiency—favoring 20°C under prolonged insolation—and potential mid-afternoon cloud incursions from the west, tilting toward 18°C; GFS runs slightly warmer at 19-20°C, but model spread remains narrow (±1.5°C), with final resolution hinging on 00Z updates.
