Recent numerical weather models, including GFS and ECMWF runs, project a daily maximum of 19–20°C in Amsterdam on September 11 under mostly cloudy skies with light rain and southerly flow. This aligns closely with the 1991–2020 climatological average high of 19.6°C and reflects modest warm-air advection tempered by cloud cover and precipitation. Trader consensus, with 20°C at 58.5% implied probability and 21°C at 30%, mirrors the narrow envelope of ensemble guidance around these values, while lower and higher outcomes remain low-probability outliers. Updated model cycles and official KNMI observations tomorrow will refine the exact peak.

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.
