**Persistent cloud cover, rain, and southwest winds associated with an Atlantic low-pressure system are suppressing daytime heating in Amsterdam on September 17, 2026, positioning 18°C as the market favorite at 55.5% implied probability.** Multiple forecast models from sources including globalmeteo, Yr.no, and weather services converge on daytime maxima of 16–18°C under mostly cloudy to rainy conditions, with highs likely occurring in the afternoon before cooling overnight. This aligns with the seasonal late-September decline from early-month warmth (recent days reached 19–24°C) and historical averages near 19°C, though precipitation and reduced insolation are expected to keep readings below that benchmark. The 19°C outcome at 18.5% remains plausible if breaks in cloud cover allow brief warming, while 17°C at 17.0% reflects downside risk from heavier rain or stronger winds. Updated model runs and official observations closer to the date will refine these probabilities, as small shifts in the frontal timing or intensity can alter peak temperatures by 1–2°C.

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.
