Forecast models from sources including the Met Office and GFS consistently project a daytime high of 19–20°C for Amsterdam on September 10, 2026, under mostly cloudy to partly cloudy skies with light southwest winds and minimal precipitation risk. This aligns with the historical September average high near 19.7°C at Schiphol, driven by stable high-pressure influences and typical autumn steering patterns that limit strong warming or cooling. Current observations show morning temperatures in the low teens Celsius rising gradually, supporting trader emphasis on these two outcomes as the resolution range. Minor model variations in cloud cover or wind could nudge the exact peak by 1°C, but no significant shifts have emerged in recent updates.

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.
