Official forecasts from the Finnish Meteorological Institute and ensemble models indicate the lowest temperature in Helsinki on August 27 will occur during early morning hours under clear to partly cloudy skies, with light northerly winds promoting radiative cooling from an afternoon high near 20–21°C. This setup aligns with late-August climatology, where the 1991–2020 average low is 12.2°C and recent years show minima typically between 11–15°C absent major cold advection. Current model consensus supports a minimum near 12–13°C, with limited downside risk from drier air and stable high pressure, though minor forecast adjustments from overnight observations could still influence final readings. Trader sentiment reflected in the elevated prices for 9–10°C outcomes appears driven by historical variability rather than near-term data shifts.

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
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
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.
