Official AEMET observations from Adolfo Suárez Madrid–Barajas Airport, the market's resolution authority, recorded a maximum temperature of 15°C on April 13, 2026, anchoring trader consensus at 100% implied probability for that outcome amid cloudy skies and cool northerly airflow that suppressed daytime heating. This below-average reading for mid-April—typically 17–19°C—aligns with recent forecast models from AEMET predicting subdued highs due to a lingering cold air mass from earlier in the week. With verified hourly data now public, resolution appears certain barring rare instrument recalibration or data audit by AEMET, expected within standard reporting timelines. Traders await no further updates as uncertainty has evaporated.
