Recent forecasts from GFS and other models indicate Amsterdam will experience unsettled conditions on August 31 driven by a low-pressure system and southwest flow, bringing widespread cloud cover, scattered thunderstorms, and moderate winds that limit daytime heating. This setup favors a daily maximum near 19–20°C, below the late-August climatological average of roughly 21–22°C, as persistent moisture and reduced insolation suppress warming. Traders appear to weigh the narrow spread between these thresholds based on subtle differences in model timing of any breaks in cloud or shower intensity, with resolution hinging on the precise peak recorded at official stations. Updated runs in the next 48 hours will likely tighten consensus around the outcome.

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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
