Forecast models from agencies including the Finnish Meteorological Institute and ECMWF consensus project a daily high near 16–17°C for Helsinki on September 7, driven by weak southwesterly flow under building high pressure and limited cloud cover that permits modest daytime warming. This aligns with early-September climatology, where the long-term average high sits around 16.9°C. Light winds and dew points in the 5–8°C range support efficient radiational heating without significant advection of cooler maritime air. Ensemble spreads remain narrow, though minor variations in timing of any residual cloud could allow brief excursions to 18°C or hold the peak at 16°C. Updated model runs tonight will refine the final range ahead of official observations.

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 7 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.Forecast models from agencies including the Finnish Meteorological Institute and ECMWF consensus project a daily high near 16–17°C for Helsinki on September 7, driven by weak southwesterly flow under building high pressure and limited cloud cover that permits modest daytime warming.
