Official AEMET observations at Adolfo Suárez Madrid-Barajas Airport—the designated resolution source—have already recorded a peak temperature exceeding 23°C earlier today amid a stable high-pressure ridge delivering clear skies, light winds, and ample solar heating over central Spain. This aligns with forecast model consensus from AEMET and ECMWF ensembles predicting daytime highs around 24–25°C, well above April climatological averages of 18–20°C, as dry continental air suppresses cloud formation and enhances near-surface warming. Trader consensus reflects this skin-in-the-game certainty, with the market-implied probability at 100% for 23°C or higher. Only an improbable data revision or undocumented instrument error could alter resolution, pending AEMET's end-of-day summary.
