Recent official forecasts from sources including GFS and ECMWF models indicate northwest winds and mostly cloudy conditions will limit daytime heating in Amsterdam on September 24, supporting a highest temperature near 17–18°C. This aligns with the market's strongest implied probabilities at those levels, reflecting a modest cooling trend following warmer readings earlier in the week. Late-September climatology in the region typically features highs around 17–19°C under similar synoptic patterns, with limited potential for outliers absent major atmospheric shifts. Updated model runs and any revisions to cloud cover or wind forecasts ahead of the date remain key variables that could influence final observed maxima.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Amsterdam Airport Schiphol Station in degrees Celsius on 24 Sep '26.
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.Recent official forecasts from sources including GFS and ECMWF models indicate northwest winds and mostly cloudy conditions will limit daytime heating in Amsterdam on September 24, supporting a highest temperature near 17–18°C.
