Recent European forecast models, including ECMWF ensemble runs, indicate mixed springtime conditions over the North Sea region that keep Amsterdam’s maximum temperature for May 18 centered near 15 °C. Persistent cloud cover and moderate northwesterly flow are limiting daytime warming, while any brief clearing or slight southerly shift could push readings to 16 °C. These competing signals produce tightly clustered market probabilities around 14–16 °C, reflecting the inherent uncertainty in short-range temperature forecasts this close to the date. Updated model guidance and real-time surface observations expected in the next 24 hours will be the key catalysts that refine the final outcome.
