Recent forecast consensus from models including those referenced by Finnish Meteorological Institute and international sources points to overnight lows in Helsinki around 12–13°C on September 17, driven by persistent southwesterly flow advecting milder Atlantic air and extensive cloud cover limiting radiative cooling. This setup aligns with current market-implied odds favoring 16°C or higher (46.5%) alongside notable support for 11°C (33.0%) and 10°C (28.0%), as traders weigh the potential for slightly stronger cooling if winds ease. Historical September 17 averages show a typical low near 9.1°C, but 2026 conditions remain above baseline due to broader regional warmth. Updated model runs overnight and final observational data from Helsinki stations will refine resolution criteria for the minimum temperature.

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.
