Official KNMI observations at Amsterdam Airport Schiphol confirm the highest temperature on May 2, 2026, reached exactly 20°C, anchoring trader consensus at 100% implied probability for that outcome as markets near resolution. This result stems from an unstable maritime air mass over the North Sea, delivering a mix of afternoon sunshine and convective showers that capped peak warming despite early model runs from ECMWF and Harmonie forecasting 19–21°C highs. Compared to Schiphol's climatological May average of 16.5°C, the reading reflects mild spring conditions influenced by weak southerly flow ahead of a cold front. Realistic challenges are minimal but could arise from rare KNMI data reviews or instrument recalibrations, though verified synoptic measurements rarely shift post-publication.
