Latest numerical weather prediction models from agencies including the Met Office and ECMWF indicate Madrid maximum temperatures on August 24 will likely fall in the 27–29 °C range, driven by a shift to southwesterly flow and increased cloud cover that limits daytime heating compared with earlier August peaks near 32 °C. Ensemble spreads remain modest, reflecting uncertainty mainly in the timing and extent of any scattered showers or breaks of sun, which could nudge readings up or down by 1–2 °C. This narrow forecast distribution aligns with the closely matched market-implied odds for 27 °C and 28 °C, while historical late-August climatology shows a typical decline from mid-month highs and supports the low probabilities assigned to extremes above 30 °C or below 26 °C. Updated model runs and official observations over the next 48 hours will provide the clearest signals ahead of market resolution.
