Recent model consensus from AEMET and ECMWF places Madrid’s July 8 maximum near 39–40 °C amid a persistent heat dome over central Spain, with limited cloud cover and weak winds favoring daytime heating. The 2026 summer’s record warmth—1.6 °C above average through June—has sustained elevated baseline temperatures, while ensemble spreads of roughly ±1–2 °C keep 39 °C and 40 °C brackets nearly even in trader pricing. Official warnings highlight the 38–41 °C window as most probable, with slight upside risk if subsidence strengthens further before the July 8 verification window closes.
