Trader consensus on Polymarket assigns a 34.5% implied probability to a 13°C high in Amsterdam on April 19, edging out 12°C (25.5%) and 14°C (22%), reflecting tight uncertainty in short-range forecasts amid a cool northwest airflow. The latest KNMI guidance projects a 14°C maximum with moderate showers alternating with sun, 50% precipitation chance, northwest winds at force 3, and just 30% sunshine, factors that could cap temperatures through reduced insolation if clouds persist or boost them to 14°C with clearer breaks. ECMWF and GFS ensemble means hover around 13°C, consistent with April climatological highs near 12–13°C at Schiphol Airport, the resolution station. New model runs and observations on April 18 may sharpen the outlook.
