Official AEMET and European model guidance for Madrid on August 10, 2026, centers on 35–37 °C under persistent high pressure, clear skies, and light winds that promote strong daytime solar heating in the city’s continental setting. These conditions align with late-summer climatology where average maxima reach 32–34 °C yet allow modest elevation when subsidence and dry air persist. Recent model runs show limited spread, with most solutions clustering near 36 °C and only modest urban-heat-island or boundary-layer warming potential pushing a minority toward 38 °C. Traders therefore assign the highest implied probability to 37 °C, reflecting consensus on the absence of cooling advection or increased cloud cover before resolution.
