Recent forecasts from multiple models project Madrid's overnight low on August 26 near 17–19 °C, consistent with the long-term average of 18.5 °C for the date. Light southwesterly winds of 5–15 km/h, dew points near 9–10 °C, and partly cloudy skies support moderate radiative cooling after daytime highs around 28 °C, with limited cloud cover preventing strong warming. The tightly clustered market probabilities around 14–17 °C reflect genuine uncertainty in the precise minimum, driven by small differences in forecast wind speeds, timing of any increased cloudiness, and local urban heat-island effects that can alter overnight temperature drops by 1–2 °C. Updated model runs and AEMET guidance expected in the next 24 hours will likely resolve the narrow spread.
