Current forecasts from European models, including ECMWF and GFS runs, place Amsterdam’s June 6 maximum near 18–19 °C under a moderate westerly flow influenced by the relatively cool North Sea. Persistent cloud cover and light showers expected through the afternoon limit surface heating, while modest Atlantic ridging prevents stronger warm-air advection. Historical June climatology for the region shows daily highs averaging 18–20 °C with low day-to-day variability this early in the season. Traders have therefore concentrated probability on the 18–20 °C outcomes, with the slight edge to 19 °C reflecting the latest ensemble guidance. Updated model cycles and KNMI observational verification tomorrow morning will determine the final recorded high.
