Latest ensemble guidance from ECMWF, KNMI, and the UK Met Office converges on a 26–28 °C daytime maximum for Amsterdam on 18 June, driven by a south-westerly flow advecting mild air under partly cloudy skies with moderate insolation. The near-even split between 27 °C and 28 °C implied probabilities reflects small differences in predicted cloud fraction and boundary-layer mixing across model runs, with limited scope for higher values given the modest thermal advection and typical June sea-breeze moderation. Historical climatology places the June mean maximum near 20–22 °C, so current conditions represent a clear positive anomaly whose exact peak hinges on the next 48-hour model updates.
