Official forecasts from European meteorological agencies project a daytime maximum near 21°C in Amsterdam on August 18 amid persistent cloud cover, light rain, and moderate northwesterly winds that limit solar heating. These conditions align with typical mid-August patterns where Atlantic moisture suppresses peaks below seasonal averages of 22°C. Model consensus shows limited potential for brief clearing that could allow a brief spike toward 22°C, while heavier showers would cap readings at 20°C or lower. Traders price the narrow 21–22°C band highest because observational data and short-range guidance remain closely balanced, with resolution hinging on the precise timing of any convective activity.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Amsterdam Airport Schiphol Station in degrees Celsius on 18 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Amsterdam Airport Schiphol Station, available here: https://www.wunderground.com/history/daily/nl/schiphol/EHAM.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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.
