Traders heavily favor 18°C (40%) as Madrid's highest temperature on March 22, driven by the latest ensemble forecasts from AEMET and ECMWF models, which converge on daytime highs of 17-19°C amid mild Atlantic airflow and weak high-pressure influence. Recent developments, including yesterday's model runs showing slight cooling from earlier 20°C projections due to incoming cloud cover and northerly winds, have boosted probabilities for 18°C and 19°C while diminishing outliers like 21°C+. March climatology supports this, with historical highs averaging 17.5°C and rare extremes beyond 22°C; ongoing uncertainty stems from short-range mesoscale changes, with official observations resolving via AEMET stations at Madrid-Barajas Airport.
