Trader consensus overwhelmingly favors a maximum temperature of 12°C or below in Madrid on March 20, driven by authoritative forecasts from AEMET and ECMWF models predicting persistent low pressure, northerly winds, and cloud cover amid a late-winter cold snap across Iberia. Verified ensemble projections cluster highs at 8–12°C, consistent with recent observations of below-average conditions (Madrid's March climatological mean is ~15°C). This positioning reflects high model agreement, with minimal spread indicating low uncertainty. Realistic challenges include an abrupt high-pressure ridge or foehn-like warming from the Sierra de Guadarrama, though such scenarios carry <5% probability per current guidance from NOAA GFS and UKMO ensembles.
