Current numerical weather prediction models from AEMET and international sources such as the Met Office and timeanddate project a maximum temperature near 38–39 °C for Madrid on August 14, supported by typical mid-August continental conditions featuring high pressure, light winds, and clear to partly cloudy skies that favor daytime heating. These forecasts align with the market’s strongest implied probabilities at 39 °C (48 %) and 38 °C (27.5 %), reflecting the narrow uncertainty range typical two days ahead when model consensus is high. Recent runs show limited spread, though small shifts in timing of any cloud cover or slight changes in 850 hPa temperatures could still push the observed high into the 40 °C bin. Traders are therefore weighting the most probable outcome near the upper end of normal August variability rather than extreme heatwave thresholds.
