Recent forecasts from models including those referenced by AEMET and European ensembles point to peak temperatures in Madrid on June 24 likely falling between 38–40 °C under a persistent high-pressure ridge, clear skies, and light winds that favor strong daytime heating. Consensus among runs shows afternoon maxima near 39 °C as the most probable outcome, though small differences in boundary-layer moisture or slight shifts in the ridge axis could push readings to 38 °C or allow a brief spike to 40 °C. With resolution based on official daily maximum observations, traders are weighing the latest model guidance against typical late-June climatology of 30–36 °C highs while noting limited upside beyond 41 °C given current steering patterns.
