**Latest forecast guidance from sources including the Met Office, ECMWF-influenced models, and GFS points to a daytime maximum near 19°C in Amsterdam on October 13, with light rain, southerly winds around 15–25 km/h, and high humidity near 85% moderating further warming.** This aligns with the market’s tight split between 19°C and 20°C outcomes, as modest model differences in cloud cover and advection could tip the peak by 1°C. Persistent overcast skies and precipitation are expected to limit solar heating despite the mild southerly flow, consistent with typical October maritime conditions where highs average around 15–16°C. Traders are closely watching the next model updates for any shift in the thermal profile before resolution.
