Trader consensus heavily favors 17°C (45.5%) and 18°C (30%) as Madrid's highest temperature on March 23, driven by the latest ECMWF and GFS model runs projecting mild highs in this range amid a stable high-pressure ridge over Iberia. AEMET's short-range forecast aligns, indicating partly cloudy skies with light southerly winds capping daytime peaks below 19°C, consistent with March climatology where average highs hover at 16-17°C and exceed 20°C only 10% of the time historically. Recent observations show Madrid's early-week temps stabilizing at 15-17°C, reducing outlier risks like 14°C lows (1.7%) or 20°C+ spikes (under 4% combined), though minor model divergences could shift odds before official measurements at Barajas Airport.
