**Official observations from Spain's Agencia Estatal de Meteorología (AEMET) at Adolfo Suárez Madrid-Barajas Airport—the market's designated measurement site—recorded a maximum temperature of 18°C on March 27, 2026, solidifying trader consensus at 100% implied probability for that outcome.** This reading aligns with late-March climatological norms for Madrid, where typical highs range 16–19°C under variable spring atmospheric patterns influenced by continental air masses and occasional cloud cover, as seen in preliminary hourly data released late Friday. Pre-event forecast models from AEMET and ECMWF had converged on 17–19°C peaks amid moderate winds and partial sunshine, with no late-day surges observed. Scenarios challenging this include rare official data revisions from quality control or instrument recalibrations, though such adjustments occur infrequently for established airport stations; final AEMET daily summaries expected shortly will confirm resolution.
