Traders currently price "31°C" at 54% for "Highest temperature in Madrid on August 15?". Over the past 24 hours that probability moved up 31.5 points. Full distribution: 31°C 54%, 30°C or below 31%, 32°C 10%, 33°C 8%. The market has traded $109K in total volume and resolves Aug 15, 2026. Forecast models from AEMET and ECMWF show a stable late-summer high-pressure ridge over central Iberia on August 15, 2026, favoring daytime maxima near 31–33°C in Madrid under mostly clear, subsiding air. This synoptic setup explains the market’s strong 59% implied probability on 31°C, with 30°C or below at 22% reflecting modest cooling risks from any weak frontal timing. Recent observations of 37–38°C peaks on August 13–14 underscore a sharp transition driven by shifting steering patterns. Ensemble spreads remain broad due to uncertainties in boundary-layer mixing and exact front passage, keeping probabilities low for extremes above 35°C despite the month’s climatological baseline of 32–34°C highs. Updated model runs and official briefings will refine resolution criteria around peak afternoon readings.
