Trader consensus overwhelmingly favors 18°C as Madrid's highest temperature on March 18, driven by high-resolution forecasts from AEMET and ECMWF models converging on this exact value amid stable spring-like conditions with light winds and partial cloud cover. Verified ensemble predictions show temperatures peaking mid-afternoon around 17-19°C, aligning with historical March maxima averaging 16-18°C at Barajas Airport, the market's likely reference station. This positioning reflects low model spread and minimal convective activity risks. Realistic challenges include an unforeseen southerly foehn wind pushing 20°C+ or cold air advection dropping below 17°C, though current upper-air patterns make deviations unlikely beyond ±1°C.
