Latest ensemble forecasts from the Finnish Meteorological Institute and ECMWF place Helsinki-Vantaa’s May 17 daytime maximum in the narrow 16–17 °C band, reflecting light southerly advection of mild continental air under a weakening high-pressure ridge. Subtle model disagreements on afternoon cloud timing and boundary-layer mixing create the tight clustering between these two outcomes, while historical mid-May climatology averages 15 °C highs with occasional +2 °C anomalies during spring warming episodes. Resolution hinges on official 24-hour maximum readings once insolation peaks and any thin high cloud or brief frontal influence materializes; traders therefore track the next FMI hourly update for any revision in peak heating potential.

This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 17 May '26.
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 Helsinki Vantaa Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/fi/vantaa/EFHK.
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.Latest ensemble forecasts from the Finnish Meteorological Institute and ECMWF place Helsinki-Vantaa’s May 17 daytime maximum in the narrow 16–17 °C band, reflecting light southerly advection of mild continental air under a weakening high-pressure ridge.
