Recent forecast models from multiple agencies converge on overnight lows of 13–14°C in Amsterdam on August 21, driven by persistent cloud cover, light northerly winds, and elevated dew points that suppress radiative cooling after daytime highs near 20–21°C. These conditions align closely with the historical August 21 average low of 13.1°C at Schiphol, while recent northerly flow has kept temperatures modestly below late-summer norms. Trader consensus splits evenly between 13°C and 14°C because small differences in cloud timing or wind speed could shift the minimum by 1°C, with updated model runs and real-time observations from the evening hours serving as the next key resolution signals.

This market will resolve based on the lowest 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 lowest temperature recorded at the Amsterdam Airport Schiphol Station in degrees Celsius on 21 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.
