**Trader sentiment for the highest temperature in Amsterdam on September 17 centers on 18°C (59.5% implied probability) due to consistent short-range model consensus showing a daytime maximum near that level.** Forecasts from sources including GFS-based guidance and official agencies indicate persistent cloud cover, widespread rain, and moderate southwesterly flow on the 17th, which limits solar heating and caps highs around 16–18°C (roughly 61–65°F). This aligns with a slightly cooler-than-average September 2026 trend so far, where regional temperatures have run about 1–2°C below long-term normals. Historical data for mid-September place the typical high near 19°C, but the active low-pressure influence and high precipitation probabilities (often 70–90%) reduce the chance of reaching that threshold. Minor model spread keeps 17°C as a secondary outcome (28.5%), while warmer or cooler extremes remain low-probability outliers pending any last-minute forecast shifts.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Amsterdam Airport Schiphol Station in degrees Celsius on 17 Sep '26.
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.**Trader sentiment for the highest temperature in Amsterdam on September 17 centers on 18°C (59.5% implied probability) due to consistent short-range model consensus showing a daytime maximum near that level.**
