Trader consensus overwhelmingly favors 18°C as Madrid's highest temperature on March 24, driven by the latest numerical weather prediction models from AEMET and ECMWF, which forecast a daytime maximum of 18°C under partly cloudy skies with light winds. Historical March data from AEMET shows average highs around 16-18°C, aligning with current mild Atlantic airflow suppressing warmer anomalies. Supporting evidence includes consistent GFS ensemble runs capping peaks at 17-19°C and minimal urban heat island amplification expected. Realistic challenges include an unforeseen southerly foehn wind gust or model underestimation of insolation, potentially pushing toward 19-20°C, though low-probability per ensemble spreads.
