Recent forecasts from multiple models converge on a daytime high near 18–19°C for Amsterdam on September 20, with westerly flow, increasing cloud cover, and a modest chance of showers limiting further warming. These conditions align with typical late-September maritime patterns influenced by the North Atlantic, where cool sea-surface temperatures and moderate wind speeds suppress peak readings below the month’s earlier warmth. Trader consensus favoring 19°C reflects this model agreement and historical September averages around 19°C, while the secondary 20°C probability accounts for residual uncertainty in cloud timing and any brief clearing. Upcoming model runs and official updates from European meteorological agencies will likely refine these probabilities as the date approaches.

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.
