Cooler maritime air and persistent westerly flow are suppressing maximum temperatures in Amsterdam on September 9, with official short-range forecasts from sources like ECMWF and GFS indicating a high near 17–18°C amid widespread rain and 15–20 km/h winds. This follows a sharp drop from unseasonably warm readings above 26°C on September 7, driven by an advancing frontal system that has increased cloud cover and precipitation chances to 70–90%. Historical September averages near 19–20°C provide context, yet current model consensus and observational trends favor the lower end of the distribution. Traders appear to weigh the limited upside potential from any forecast revision against the high likelihood of staying below 19°C, with resolution hinging on the precise daily maximum recorded at the official station.

The resolution source for this market will be information from NOAA, specifically the highest 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.
