Trader consensus on Polymarket overwhelmingly backs a highest temperature of 22°C in Madrid on March 25, reflecting near-unanimous agreement from leading forecast models like ECMWF ensembles and AEMET guidance, which project mild late-winter conditions under a stable high-pressure ridge with light southerly winds and clear skies limiting daytime heating. Observational data from recent days shows consistent temperatures in the low-20s°C range amid typical March climatology, where Madrid's average highs hover around 16–18°C but occasionally spike modestly without extremes. This positioning is reinforced by model convergence in the past 48 hours, ruling out hotter scenarios absent a sudden warm front. Realistic challenges include unanticipated Saharan dust influx boosting solar insolation or microscale urban heat effects, though probabilities remain negligible per current ensemble spreads; final hourly observations from official stations will confirm resolution.
