Latest ECMWF and GFS model runs forecast a daytime maximum of 20–21°C in Amsterdam on September 13, shaped by moderate westerly flow, extensive cloud cover, and scattered showers that suppress peak heating. These conditions align closely with the market’s leading 20°C and 21°C outcomes, which together exceed 90% implied probability. Mid-September climatology shows an average high near 19.5°C at Schiphol, so the current setup reflects typical seasonal moderation rather than an anomalous warm surge. Short-range model agreement is high, though the precise peak remains sensitive to the timing and intensity of any convective cells; official KNMI observations will determine final resolution.

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.
