Current ensemble forecasts for Amsterdam on September 28 point to a daily minimum near 15–17°C, driven by moderating North Sea influence, moderate southerly to northeasterly flow, and extensive cloud cover limiting nighttime radiative cooling. Historical late-September averages near 10–11°C provide context, yet persistent mild advection and dew points around 14–16°C support the higher baseline. Close market odds between sub-11°C and 21°C+ outcomes reflect model spread in wind shifts and precipitation timing, which could enhance or suppress cooling; updated runs from agencies like KNMI or ECMWF will clarify thresholds ahead of resolution.
