Current ensemble forecasts from the Finnish Meteorological Institute and global models indicate an overnight minimum near 13–14°C for Helsinki on August 28 under mostly cloudy skies, light southeast winds, and stable high pressure. This aligns with late-August climatology (average low ~12°C) and recent model consensus showing limited cooling potential without a strong frontal passage. Trader emphasis on these two outcomes reflects narrow spreads in predicted dew points and cloud cover, which determine whether the minimum dips to 13°C or holds at 14°C before sunrise. Minor model disagreements on timing and humidity could still shift the exact reading, though probabilities below 10°C or above 15°C remain low given the current pattern.

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 28 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
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.Current ensemble forecasts from the Finnish Meteorological Institute and global models indicate an overnight minimum near 13–14°C for Helsinki on August 28 under mostly cloudy skies, light southeast winds, and stable high pressure.
