Clear skies and moderate northwesterly winds are driving overnight radiative cooling in Helsinki, with forecast models from the Finnish Meteorological Institute and ECMWF showing minimum temperatures clustering around 6–7 °C for September 6. These conditions contrast with the 1991–2020 climatological average low of 10.8 °C, as a cooler air mass and low dew points near 2–4 °C enhance heat loss. Slight differences among leading outcomes (5–7 °C) stem from model variations in exact wind mixing and the precise hour of the daily minimum, while probabilities below 4 °C remain low given current observations and historical September extremes rarely dipping that far this early in the month. Updated model runs and official station readings will refine the final value.

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 6 Sep '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 for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.Clear skies and moderate northwesterly winds are driving overnight radiative cooling in Helsinki, with forecast models from the Finnish Meteorological Institute and ECMWF showing minimum temperatures clustering around 6–7 °C for September 6.
