**Trader consensus at 100% for a 17°C high in Helsinki on September 10, 2026, reflects tight alignment across operational forecasts and real-time observations.** Multiple model runs, including GFS and regional guidance, along with data from Helsinki-Vantaa and Kaisaniemi stations, show daytime peaks of 16–18°C under mostly cloudy skies with light rain and northwest winds of 3–6 m/s. This matches the climatological average high of roughly 16.4°C for the date while falling short of recent warmer analogs. With the daily maximum likely already recorded in afternoon hours, only an unexpected late surge or station-specific anomaly would shift the outcome; official Finnish Meteorological Institute verification is expected to confirm the 17°C threshold.

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 10 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.**Trader consensus at 100% for a 17°C high in Helsinki on September 10, 2026, reflects tight alignment across operational forecasts and real-time observations.** Multiple model runs, including GFS and regional guidance, along with data from Helsinki-Vantaa and Kaisaniemi stations, show daytime peaks of 16–18°C under mostly cloudy skies with light rain and northwest winds of 3–6 m/s.
