Latest ensemble forecasts from ECMWF and GFS models indicate mild overnight conditions for Amsterdam on September 18 under persistent southwesterly flow and mostly cloudy skies, keeping the minimum temperature likely between 12–15 °C and underpinning the closely matched market-implied odds across the 12–17 °C outcomes. Differentiation among these bins hinges on small variations in cloud cover timing, which modulates radiative cooling, and boundary-layer wind speeds that influence mixing with the relatively warm North Sea air mass. Historical September averages near 11 °C provide context, but current model consensus shows limited potential for stronger cooling unless a clearer slot develops late in the night. Updated high-resolution runs and local observations from KNMI will refine the exact minimum before resolution.

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.
