Current forecasts from Spain’s AEMET and supporting models point to a daytime maximum near 36°C in Madrid on August 5 under a stable high-pressure regime, clear skies, and light winds over the central Meseta. These conditions favor strong solar radiative heating without significant moisture or cooler advection, consistent with midsummer climatology where average highs reach 32–33°C but peak days often hit 35–37°C. The market’s 76.5% implied probability for 36°C reflects trader weighting of the latest guidance and real-time observations, while the 16% share for 37°C captures residual model spread. Minor variance to 35°C remains possible if boundary-layer mixing increases slightly, but no Saharan plume or heatwave signals are present to elevate odds for 38°C or higher. Official maximum readings will resolve the market by close of day.
