Latest KNMI forecasts project a maximum temperature of 17°C in Amsterdam on April 15 under mostly sunny skies with light southeasterly winds and only 10% precipitation chance, driving trader consensus toward 17°C (26%) and 18°C (33%) as leading outcomes. This reflects ECMWF and GFS ensemble spreads of 12–18°C, stemming from uncertainty in low-level cloud cover clearance and its impact on solar heating—faster dissipation could yield 18–19°C, while persistent stratus favors 16–17°C. Southeasterly flow ushers warmer continental air above the mid-April climatological average of 13–14°C, amid a high-pressure ridge. New 12Z model runs expected April 13 may refine probabilities ahead of resolution.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Amsterdam Airport Schiphol Station once information is finalized, 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 to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
