Recent forecasts from European models indicate Helsinki will experience high pressure and light northwest winds on August 25, favoring clear to partly cloudy skies that promote overnight radiative cooling. Official guidance points to daytime highs near 19–21°C, with nighttime lows likely settling between 10–13°C depending on cloud breaks and boundary-layer mixing. The tight spread between the 12°C outcome and 7°C-or-below reflects uncertainty in exact minimums, as small variations in dew-point depression or residual cloud cover can shift readings by 2–3°C. Traders weigh historical late-August climatology—typical overnight lows near 11–12°C—against the current stable, dry pattern that limits further cooling. Updated model runs and Finnish Meteorological Institute briefings in the next 24 hours will refine resolution odds.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Helsinki Vantaa Airport Station in degrees Celsius on 25 Aug '26.
The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=efhk
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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.Recent forecasts from European models indicate Helsinki will experience high pressure and light northwest winds on August 25, favoring clear to partly cloudy skies that promote overnight radiative cooling.
