**Forecast models from ECMWF and the Dutch KNMI’s HARMONIE system show a post-heatwave transition over the North Sea region, with Atlantic air moderating temperatures after early-August peaks above 32 °C.** For Amsterdam on 20 August, guidance consistently points to a daytime maximum near 21 °C under a mix of broken cloud and light showers, with moderate south-westerly winds limiting afternoon warming. Coastal sea-breeze effects and possible rain timing introduce the narrow spread that places 20–22 °C outcomes within a few percentage points of each other on the market. Ensemble members differ mainly on exact cloud cover and shower timing rather than large-scale advection, keeping the distribution tightly centered on the long-term August average of ~21 °C. Updated model runs and any last-minute satellite observations of upstream cloud bands will be the key near-term drivers of shifts in implied probabilities.
