Current forecasts from the Royal Netherlands Meteorological Institute and European models indicate a daytime high near 25–26°C in Amsterdam on May 22, driven by a strengthening southwesterly flow that brings warmer air from the continent under mostly sunny skies with light winds. This setup favors the market’s leading 26°C outcome at 36.5% implied probability, as model consensus shows limited cloud cover and no significant frontal passage to suppress temperatures. Historical May climatology places the average daily maximum around 18–20°C, so the current pattern represents a notable warm anomaly consistent with recent model runs. Updated guidance tomorrow morning will refine the exact peak, particularly any late-day cooling from increased marine influence.
