Trader consensus overwhelmingly favors 17°C as Madrid's highest temperature on March 23, driven by official observations from Spain's AEMET meteorological agency, which recorded a peak of 17°C at key stations like Barajas Airport amid mild spring conditions. Long-range ECMWF and GFS models had forecasted highs in the 15-18°C range, aligning with March climatology where Madrid averages 16°C, supported by light southerly winds and partial cloud cover suppressing extremes. This positioning reflects verified hourly data releases showing no exceedance. Realistic challenges are minimal—only a post hoc data correction from AEMET or overlooked station outlier could shift it, though such revisions are rare for settled daily maxima.
