Recent forecasts from the Finnish Meteorological Institute, Foreca, and Yr.no point to a September 8 high near 17–19 °C in Helsinki, driven by a shift to southerly flow that advects milder maritime air ahead of an approaching frontal system. Model consensus shows mostly cloudy skies with a chance of light rain, which would cap daytime heating and keep the maximum below the seasonal record but above the long-term September average of roughly 16.7 °C. Trader emphasis on the 18 °C outcome reflects this narrow range, while slight model spread on precipitation timing and wind strength sustains smaller probabilities for 17 °C or 19 °C. Updated runs from official agencies over the next 48 hours will refine the exact peak before market resolution.

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 forecasts from the Finnish Meteorological Institute, Foreca, and Yr.no point to a September 8 high near 17–19 °C in Helsinki, driven by a shift to southerly flow that advects milder maritime air ahead of an approaching frontal system.
