Latest KNMI guidance and ECMWF/GFS ensemble forecasts point to a maximum temperature around 14°C at Amsterdam Airport Schiphol on April 18, driven by light westerly winds ushering cooler maritime air, morning showers in Noord-Holland (50% chance, ~2 mm total), and partial cloud cover limiting solar heating. This positions 14°C as the market-implied leader at 45.5% trader consensus, flanked closely by 15°C (22%) and 13°C (21%), reflecting model spread amid uncertainty in afternoon clearing. Cooler than today's observed 18°C high, odds align with April climatological norms near 13°C; final resolution hinges on official Schiphol measurements by midnight. New hourly updates could refine probabilities before close.
