**Latest forecasts from agencies like AEMET and European models show Madrid reaching a daytime maximum near 37°C on September 6 under clear skies, light southwesterly winds, and strong daytime heating.** This aligns with the market's near-certain consensus at 37°C, as current observations track toward that threshold without signs of significant deviation. Historical September averages sit around 29°C, but an ongoing warm anomaly and minimal cloud cover support the elevated reading. Resolution depends on the official daily maximum at the reference station. Minor shifts in timing, localized cooling from brief cloud build-up, or slight wind changes could still push the final value to 36°C or 38°C, though model agreement currently limits that likelihood.
