The latest KNMI forecast, issued early on April 5, projects a maximum temperature of 15°C near Amsterdam—likely at Schiphol Airport station—under mostly sunny skies with 70% sunshine, light southwest winds at force 3, and no precipitation, following a chilly minimum of 3°C. However, Polymarket's trader consensus implies 12°C (51.5%) and 13°C (35%) as leading outcomes, incorporating uncertainty from global model ensembles like ECMWF and GFS that show slight spreads around 12–14°C, coastal marine layer effects tempering peaks, and early April climatology averaging 12°C highs amid variable North Sea influences. April 5 observations hit 13–14°C nationally amid building high pressure, with intraday Schiphol data set to resolve the market.
