Trader sentiment favors 15°C or below at 35% for Madrid's highest temperature on March 26, closely trailed by 16°C and 17°C at 25.5% each, reflecting ECMWF and GFS ensemble means clustering around 16-17°C amid a cool northerly airflow and Atlantic low-pressure influence. Recent model runs show tightening consensus after earlier warmer signals faded, with AEMET forecasts emphasizing partly cloudy conditions capping diurnal heating. Key differentiators include cloud cover timing—prolonging overnight chill for sub-16°C outcomes—and light showers risking further suppression, against historical late-March averages of 17°C; upper outcomes fade due to constrained solar insolation and no heat dome signal.
