Recent forecasts from multiple models indicate Madrid will reach a daily maximum near 27–28°C on August 25 under partly cloudy skies, southwesterly winds of 10–15 km/h, and low precipitation chances, consistent with cooling late-summer conditions after earlier heat. This positions 29°C as the market favorite at 61.5% implied probability, reflecting minor upside uncertainty in official station readings and model spread, while 28°C trails at 24%. The 30°C outcome at 12.5% captures residual potential for localized warming, though climatological baselines near 31°C have been tempered by current atmospheric patterns. Resolution hinges on the precise maximum from the primary Madrid observing site, with final model updates expected overnight.
