Official forecasts from the Royal Netherlands Meteorological Institute (KNMI) and consensus from GFS and other models indicate a maximum of 19–20°C for Amsterdam on August 23, 2026, driven by moderate northwest winds advecting cooler maritime air and persistent cloud cover that limits daytime heating. Morning observations near 16–17°C align with these projections, with afternoon peaks expected under mostly cloudy skies and light precipitation risk. This places current conditions below the 1991–2020 climatological average high of 21.7°C. Trader-implied odds favor 20°C as the most likely outcome, reflecting model agreement and stable conditions ahead of final daily measurements used for market resolution.

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 23 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.
