Latest forecast models from the Finnish Meteorological Institute and European ensembles indicate stable high pressure near 1028 hPa with light winds and limited cloud cover, favoring radiational cooling overnight and supporting minimum temperatures clustered around 11–13°C. Slight differences in model timing for peak cooling, boundary-layer moisture, and any patchy high clouds create the tight spread among these outcomes, while historical late-August climatology for Helsinki shows typical lows near 12°C. Traders weigh the latest hourly guidance and any model consensus shifts ahead of resolution on August 27.

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.
