Recent official forecasts from sources including the ECMWF and GFS models indicate a high near 18–19°C in Amsterdam on September 18 under mostly cloudy to partly cloudy skies with moderate westerly flow. This consensus, following several cooler, rainier days, positions 19°C as the market leader by aligning with typical mid-September climatology near 18.9°C while accounting for limited diurnal warming and cloud cover that caps peaks. Minor model spread allows a smaller probability for 20°C if clearer breaks occur, but persistent moisture and winds from the southwest reduce upside potential, with updated guidance expected to refine resolution criteria ahead of the date.

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.
