AEMET's latest forecast pins Madrid's April 17 high at 26°C under a stabilizing high-pressure ridge across the Iberian Peninsula, driving trader consensus with 32% implied odds on 27°C edging out 30% on 26°C amid model ensemble means hovering near 26.5°C. Recent observations underscore the warming trend, with Retiro station hitting 21.1°C maximum on April 14 before projected rises to 23°C today and 25°C tomorrow, supported by clear skies, light NE winds at 10 km/h, and 0% precipitation risk enabling peak insolation. Differentiating factors include minor ensemble spread from ECMWF and GFS runs—warmer members factoring enhanced boundary-layer mixing versus cooler ones with potential thin clouds—against Madrid's April climatological average of 19°C. New 12Z model updates today and tomorrow will likely refine these tight probabilities before resolution.
