Trader consensus on Polymarket favors 19°C (42% implied probability) and 18°C (26%) as the highest temperature at Amsterdam Airport Schiphol on April 15, driven by the Koninklijk Nederlands Meteorologisch Instituut (KNMI)'s latest short-range forecast projecting a daily maximum of 18°C under partly cloudy skies with light showers (30% chance, 1 mm total) alternating with sun, moderate westerly winds (Beaufort 3), and 50% sunshine. This positions outcomes above the mid-April climatological average of ~12°C, following April 14's observed high near 15°C amid a mild warming trend in westerly flow. Ensemble model runs reflect tight uncertainty around 17–20°C due to variable cloud cover and precipitation potential, with final observations determining resolution after midnight.
