**Trader sentiment for Madrid's August 22 minimum temperature centers on a tight cluster around 17–19°C, reflecting stable high-pressure conditions and consistent model guidance from AEMET and global ensembles.** Official forecasts indicate a minimum near 18°C under clear to partly cloudy skies with light winds, promoting moderate nocturnal radiative cooling while the urban heat island effect prevents sharper drops. Recent model runs show minimal spread, with consensus lows between 17–19°C driven by typical late-August subsidence and no incoming fronts or significant moisture. This positioning aligns with climatological baselines for Madrid in mid-to-late August, where average overnight lows hover near 16–18°C. The near-even implied probabilities across the top three outcomes capture residual uncertainty in exact boundary-layer cooling rates and localized measurement variations at official stations. No major shifts have occurred in the past 48 hours, keeping the market balanced ahead of final observations.
