Official AEMET observations confirm that the highest temperature in Madrid on April 14 reached 21°C, driving trader consensus to a 100% implied probability for this outcome, with negligible volume on cooler scenarios like 15°C or below. This aligns with pre-event numerical weather prediction models, including ECMWF and AEMET's own forecasts, which projected highs of 20–22°C under a stable high-pressure ridge promoting clear skies, light westerly winds, and above-average insolation for mid-April—when climatological norms hover around 18°C. Observational data from key stations like Barajas and city centers validated these projections precisely. While final data audits are routine, significant revisions are rare absent sensor anomalies, solidifying the market's positioning.
