Forecast models from sources like GFS and local agencies show Amsterdam's September 21 minimum temperature likely falling in the 12–15°C range, driven by building high pressure, light westerly winds, and partial overnight cloud cover that limits radiative cooling. Recent mild conditions with above-average September temperatures have kept the air mass warmer than climatological norms, reducing odds of sharp drops below 10°C while making a surge above 17°C unlikely without strong southerly flow. Model consensus points to stable steering patterns with low precipitation risk, though small variations in cloud timing or wind speed could shift the exact low by 2–3°C. Updated runs from major centers ahead of the 21st will clarify whether the night trends toward the lower or middle end of the distribution.

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.
