Recent numerical weather prediction runs from AEMET, ECMWF, and GFS show Madrid’s maximum temperature on August 26 settling near 28–29 °C, driven by a transition to cooler Atlantic air, increased cloud cover, and moderate southwesterly flow that limits daytime heating. This marks a notable drop from recent highs above 32 °C, consistent with late-summer climatology as seasonal cooling accelerates. Ensemble guidance exhibits limited spread around these values, supporting the market’s concentration on 28–30 °C outcomes while leaving room for minor revisions from the final model updates or local urban effects.
