Current forecasts from Spain’s AEMET and supporting models indicate Madrid will reach a daytime maximum near 27–28°C on October 1, 2026, under mostly cloudy skies that limit solar heating alongside moderate northeasterly flow. These conditions align with early-October climatology, where the long-term average high is roughly 23°C and extremes above 30°C remain uncommon. The resulting temperature profile places the day’s peak firmly in the 29°C range, underpinning the market’s overwhelming consensus for that outcome while assigning negligible probability to 33°C or higher. Final station readings could shift slightly with any late-day clearing, yet model agreement leaves little scope for such a revision.
