Trader consensus on Polymarket heavily favors a high temperature of 19°C (36% implied probability) for Madrid on May 7, driven by yesterday's observed maximum of 19.1°C at the Retiro station—cooler than the early May climatological average of around 22°C—and the latest AEMET forecast projecting maxima near 21°C under mostly clear skies with light northerly winds suppressing warming. Ensemble model outputs from ECMWF and GFS show consensus for highs in the 18–20°C range amid a stable high-pressure ridge and minimal cloud cover, though slight southerly shifts could nudge toward 20–21°C. AEMET's seasonal outlook signals warmer-than-normal May conditions overall, but short-term northerly flow dominates; watch evening model runs for potential refinements ahead of resolution using official Madrid measurements.
