**Current forecasts for Helsinki on September 11 point to a daily minimum near 9–10 °C under variable cloud cover and light northwesterly flow, yet market-implied odds remain nearly even between 6 °C or below and 16 °C or higher because of notable ensemble spread in short-range models.** Recent runs show modest disagreement on the arrival of a cooler maritime air mass versus continued mild Atlantic advection, with differences in predicted cloud thickness directly affecting nighttime radiative cooling rates. Historical September climatology places typical overnight lows around 9–10 °C, so any deviation hinges on whether clearer skies allow stronger surface cooling or if increased mixing and precipitation keep temperatures elevated. Updated high-resolution model output and official guidance from the Finnish Meteorological Institute over the next 24–48 hours will be the key catalysts likely to shift trader positioning.

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.
