Recent official forecasts from the Finnish Meteorological Institute and European models indicate overnight lows in Helsinki on August 28 will likely settle between 13–15°C under partly cloudy skies and light southeasterly winds. These conditions limit strong radiative cooling while the moderating influence of the Baltic Sea prevents sharper drops. With leading market outcomes clustered tightly around this range, traders are weighing minor differences in cloud cover timing and boundary-layer mixing that could shift the exact minimum by 1–2°C. Historical August climatology shows typical overnight lows near 12–13°C, providing context for current model consensus ahead of final 48-hour updates.

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.
