Recent short-range forecasts from ECMWF and GFS models indicate overnight lows near 14–15°C in Amsterdam on September 1, supporting the closely matched market-implied probabilities for those outcomes. Westerly flow with partly cloudy skies and light winds follows recent Atlantic-driven showers, moderating radiative cooling compared to clearer conditions. This aligns with early-September climatology, where average minima hover around 14°C amid transitioning seasonal patterns. Ensemble spreads remain modest given the 48-hour horizon, though minor revisions in cloud cover or wind could shift the exact minimum across adjacent bins.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
