Trader consensus on Polymarket heavily favors a highest temperature of 12°C in Amsterdam on May 14 at 48.5% implied probability, driven by the Royal Netherlands Meteorological Institute (KNMI)'s latest forecast specifying a daytime maximum of 12°C amid alternating thunderstorms, moderate rain, and sun, with 90% precipitation chance limiting solar heating. This aligns with recent HARMONIE, ECMWF, and GFS model ensembles showing a lingering cold front and northerly flow capping highs well below May climatological averages near 16–17°C, following recent observations of 11°C on May 11 and 13°C on May 12. While 13°C (24.5%) and 11°C (17%) reflect model spread uncertainty inherent to short-range forecasts, new hourly KNMI updates and observations through the afternoon landfall window could refine positioning before resolution.
