Current forecast models, including GFS runs, indicate a high near 19–20°C in Amsterdam on October 2 under building high pressure with southerly flow, light winds, and partly cloudy skies that limit daytime heating. This setup supports the market’s heavy weighting toward 20°C (57.5%) and 21°C (40.5%), well above the 1991–2020 average high of 16.9°C for the date. Recent observations from October 1 show mild conditions persisting without significant cooling signals, while model consensus remains stable ahead of tomorrow’s final readings. Minor spread in guidance around peak afternoon temperatures keeps a small probability window open for 21°C if insolation increases.
