Trader consensus on Polymarket favors a 24°C high in Madrid at 45.5% implied probability, closely trailed by 23°C (27.5%) and 25°C (20.5%), driven by the latest AEMET forecast projecting a 23°C maximum amid a stable high-pressure ridge delivering clear skies, calm winds, and zero precipitation chance. This setup maximizes solar insolation and minimizes advective cooling, enabling peak afternoon heating around 2-4 p.m. local time, though urban heat island effects and minor model divergences—such as ECMWF versus GFS runs—introduce uncertainty tipping outcomes between 23-25°C. Recent observations show April 14 maxima near 22°C, continuing the mild warming trend; real-time AEMET updates and hourly measurements today will sharpen resolution as the market nears close.
