Current short-range forecast models from sources such as the Met Office and AccuWeather indicate a maximum temperature near 20–21 °C for Amsterdam on August 18, aligning with the market’s leading outcomes at 29.5 % and 26 %. This reflects typical late-summer climatology, where average daily highs reach about 21 °C amid moderating North Sea influences that limit extreme warmth. Small probability spreads among adjacent bins arise from minor model differences in cloud cover, boundary-layer mixing, and weak frontal passages expected over the next 48 hours. Updated guidance from national meteorological agencies on August 17 will likely refine these ranges ahead of 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 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.
