Forecast models from agencies including the National Weather Service and European centers indicate a peak temperature of 25–26°C in Amsterdam on September 7, driven by southerly flow advecting mild air under partly to mostly cloudy skies that limit surface heating. Recent runs show consensus on highs near 25°C with limited diurnal range due to increasing mid-level moisture ahead of an approaching frontal system. This positions 26°C and 25°C as the leading market outcomes at 50% and 32.5% implied probability, respectively, reflecting trader alignment with ensemble guidance rather than outlier warmer scenarios. Resolution will hinge on official observations from KNMI or equivalent stations, with any late-day clearing potentially pushing readings toward the upper end of the favored range.

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.
