Current forecasts from agencies including KNMI and the Met Office indicate a maximum of 18–19°C for Amsterdam on September 18, driven by moderate southwesterly flow, partial cloud cover, and limited daytime heating under seasonal norms near 19°C. Model consensus shows low precipitation risk and stable conditions, keeping extremes unlikely and aligning with the market’s dominant 19°C (63%) and 18°C (33.5%) shares. Historical September highs average 18.9°C at Schiphol, with recent model runs showing little deviation. Final resolution depends on official hourly observations, where small timing or local variations could shift the recorded peak between the two leading outcomes.

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.
