Recent ensemble forecasts from European models, including ECMWF, point to a warm, sunny day on August 13 with maximum temperatures likely peaking between 32–34°C at Schiphol reference stations. Easterly flow is advecting warmer continental air while clear skies promote strong daytime heating under typical late-summer insolation. The tight clustering of market-implied odds around 32°C, 33°C, and 34°C reflects remaining model spread on exact timing of any thin high cloud or minor wind shifts that could trim or boost the peak by 1°C. Historical August extremes near 30°C provide context, but current synoptic setup favors values above the long-term average. Traders will monitor the next high-resolution runs and official KNMI guidance for any adjustments before 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 13 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.
