Recent ensemble forecasts from the ECMWF and regional models indicate a daytime maximum near 20–21°C in Amsterdam on September 13, with partly cloudy skies, light westerly winds around 5–10 m/s, and a chance of showers that could suppress peak heating. These conditions align closely with the historical average high of 19.5°C for the date at Schiphol, while any breaks in cloud cover or reduced precipitation would favor the slightly warmer outcome. Trader-implied odds reflect this narrow spread, as model consensus shows limited potential for either significant warming above 22°C or cooling below 19°C given the stable pressure pattern and modest diurnal range typical of mid-September maritime air. Updated short-range guidance expected overnight will likely refine the exact threshold.

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.
