Latest ensemble guidance from AEMET and ECMWF converges on a Madrid maximum of 32–34°C for August 23 under stable high pressure, light winds, and mostly clear skies, directly anchoring the market’s heavy weighting toward 33°C and 34°C. These outcomes align with late-August climatology at the Retiro station after earlier summer peaks, where ensemble spread remains minimal and favors little deviation from the median forecast. Minor uncertainties in cloud cover or boundary-layer mixing could still nudge the observed high by 1°C either way before official verification, while probabilities for outcomes below 32°C or above 35°C stay low absent any unexpected shift in the synoptic pattern. Updated model runs and AEMET bulletins over the next 48 hours will provide the final inputs ahead of resolution.
