Recent forecast guidance from the Finnish Meteorological Institute and ensemble models highlights a mild southerly flow bringing maximum temperatures of 17–19 °C to Helsinki on September 8, with 18 °C emerging as the most probable peak under partly cloudy skies and light rain chances. This aligns with climatological norms for early September, when daily highs average near 16.7 °C, and reflects the absence of stronger high-pressure ridging or cold-air advection that could shift outcomes lower. Trader consensus, reflected in the 44.5 % implied probability for 18 °C versus 23 % for 17 °C and 16 % for 19 °C, incorporates the narrow uncertainty range typical of short-range numerical weather prediction two days ahead, while the modest odds on 20 °C or higher account for possible brief warming under clearer breaks. Updated model runs and official briefings on the 7th and 8th will further refine these market-implied odds.

This market will resolve to the temperature range that contains the highest 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 highest 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.Recent forecast guidance from the Finnish Meteorological Institute and ensemble models highlights a mild southerly flow bringing maximum temperatures of 17–19 °C to Helsinki on September 8, with 18 °C emerging as the most probable peak under partly cloudy skies and light rain chances.
