**Current forecast models point to a mild overnight period for Helsinki on September 8, with the minimum temperature likely falling in the 13–15°C range.** Persistent southwesterly winds, extensive cloud cover, and elevated humidity are limiting radiative cooling, keeping temperatures from dropping toward the historical average low of 10.5°C. Official guidance from sources such as the Finnish Meteorological Institute and global models (GFS, ECMWF) shows overnight readings holding near 15–16°C early on September 8, with only modest declines possible if breaks in cloud occur. The tight clustering of market-implied odds around 12–14°C reflects trader recognition of remaining model uncertainty in exact cloud timing and wind strength, which could shift the realized low by 1–2°C. New model runs and updated FMI briefings ahead of the overnight period will provide the clearest signals for resolution.

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 8 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.**Current forecast models point to a mild overnight period for Helsinki on September 8, with the minimum temperature likely falling in the 13–15°C range.** Persistent southwesterly winds, extensive cloud cover, and elevated humidity are limiting radiative cooling, keeping temperatures from dropping toward the historical average low of 10.5°C.
