Recent ensemble forecasts from the Finnish Meteorological Institute indicate overnight lows in Helsinki near 11–12 °C on August 25 under northerly flow and building high pressure, with partly cloudy skies limiting radiative cooling. This places market-implied odds for a 10 °C minimum (37.5 %) slightly ahead of 9 °C (33.5 %) and 8 °C (31.5 %), as small differences in boundary-layer mixing, cloud timing, and exact wind direction can shift the recorded minimum by 1–2 °C. Historical August climatology shows typical overnight lows declining toward 9–11 °C by month-end, while current model consensus and limited precipitation risk keep probabilities tightly clustered around these thresholds.

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 ensemble forecasts from the Finnish Meteorological Institute indicate overnight lows in Helsinki near 11–12 °C on August 25 under northerly flow and building high pressure, with partly cloudy skies limiting radiative cooling.
