Latest ensemble and deterministic forecasts from major models point to a September 20 minimum near 13–14 °C in Amsterdam, with trader consensus clustering on those outcomes amid mild southwesterly flow and partial cloud cover. Persistent Atlantic air masses and modest pressure gradients limit nocturnal radiative cooling, while scattered showers and 15–20 kt winds further moderate the overnight drop. Historical September lows average near 11 °C, but the current pattern—driven by a weakening low to the north and building high pressure—favors values several degrees above climatology. Key uncertainties center on exact cloud timing and boundary-layer moisture, which can shift the minimum by 1–2 °C between model runs. Final resolution will hinge on official KNMI observations at the close of the meteorological day.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=eham
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
