Forecast models from sources including GFS and ECMWF indicate a high of 21–22°C for Amsterdam on September 3 under mostly cloudy skies with scattered showers and moderate westerly winds, keeping daytime heating near the long-term average of 20.6°C. Persistent cloud cover and Atlantic maritime air have suppressed stronger warming, while the absence of high-pressure blocking or southerly flow has prevented any late-summer surge. These conditions align with the market’s strong preference for 22°C, as traders weigh official guidance and historical analogs showing limited upside beyond 23°C under similar setups. Updated model runs and real-time 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.
