Trader consensus heavily favors a Madrid high of 14°C (40% implied probability), propelled by the latest ECMWF and AEMET ensemble forecasts indicating daytime maxima of 13-16°C under persistent northerly winds and high pressure dominance. Recent surface observations confirm cooler-than-average March conditions, with airport readings averaging 12-14°C last week amid reduced Atlantic moisture influence, contrasting historical late-March norms around 15.5°C. La Niña residuals contribute to this subdued outlook, though model spread (±2°C) and potential afternoon cloud breaks introduce uncertainty; traders eye tomorrow's 12Z updates for shifts before official Barajas station resolution.
