Latest numerical weather prediction runs from major centers indicate moderate uncertainty in overnight radiative cooling for Amsterdam on September 2, with model consensus pointing to a minimum temperature in the mid-teens under partly cloudy conditions and light southwesterly flow. Clearer skies would enhance longwave heat loss from the surface, favoring lower values near 14–15°C, while increased cloud cover and stronger boundary-layer mixing from the North Sea would limit cooling and support readings closer to 17–18°C. Historical climatology for early September shows typical minima around 12°C, yet current ensemble spreads and recent pressure pattern evolution keep trader-implied probabilities tightly clustered across 14–18°C outcomes. Updated model runs and observational data from KNMI stations over the next 24 hours remain the key catalysts.

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 which 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 can not resolve until the first data point for the following date has been published on the resolution source.
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.
