**Latest ensemble forecasts from sources like ECMWF and GFS place Amsterdam's September 7 maximum near 25–26°C**, driven by southerly winds advecting warmer air masses under partly cloudy skies that permit moderate surface heating. Model consensus shows afternoon peaks of 24–27°C depending on the exact timing of increasing mid-level cloud cover and wind speeds (around 4–7 m/s), which influence turbulent mixing and prevent stronger warming. The narrow spread between 25°C and 26°C outcomes reflects minor divergences in boundary-layer forecasts and short-range model updates, with traders weighting recent runs showing limited diurnal range under stable high pressure. Resolution hinges on official KNMI or equivalent station readings, where small observational adjustments could shift the outcome.

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 7 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.**Latest ensemble forecasts from sources like ECMWF and GFS place Amsterdam's September 7 maximum near 25–26°C**, driven by southerly winds advecting warmer air masses under partly cloudy skies that permit moderate surface heating.
