**Forecast models from ECMWF and the Dutch KNMI’s HARMONIE system show a post-heatwave transition over the North Sea region, with Atlantic air moderating temperatures after early-August peaks above 32 °C.** For Amsterdam on 20 August, guidance consistently points to a daytime maximum near 21 °C under a mix of broken cloud and light showers, with moderate south-westerly winds limiting afternoon warming. Coastal sea-breeze effects and possible rain timing introduce the narrow spread that places 20–22 °C outcomes within a few percentage points of each other on the market. Ensemble members differ mainly on exact cloud cover and shower timing rather than large-scale advection, keeping the distribution tightly centered on the long-term August average of ~21 °C. Updated model runs and any last-minute satellite observations of upstream cloud bands will be the key near-term drivers of shifts in implied probabilities.

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 20 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.
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.**Forecast models from ECMWF and the Dutch KNMI’s HARMONIE system show a post-heatwave transition over the North Sea region, with Atlantic air moderating temperatures after early-August peaks above 32 °C.** For Amsterdam on 20 August, guidance consistently points to a daytime maximum near 21 °C under a mix of broken cloud and light showers, with moderate south-westerly winds limiting afternoon warming.
