Latest ensemble guidance from the ECMWF and GFS, cross-checked against KNMI output, indicates a daily maximum near 26–27 °C for Amsterdam on June 18 under moderate westerly flow and partly cloudy skies. Minor variations in low-level moisture, timing of any thin high cloud, and daytime mixing depth create the narrow spread captured by trader prices, with 27 °C holding a slim lead. These values sit several degrees above the June climatological normal of roughly 19–20 °C, reflecting a transient warm advection episode rather than a persistent heatwave. Updated short-range runs issued in the past 24–48 hours have shown little shift, keeping resolution likely within the 26–28 °C band unless a last-moment change in insolation occurs.
