**Current forecast consensus from numerical weather prediction models positions 14°C as the most probable daily high for Helsinki on September 24.** Multiple runs, including those referenced by the Finnish Meteorological Institute and global ensembles, indicate a high near 14–15°C (roughly 57–59°F) under overcast skies with northeasterly flow, patchy rain or showers, and limited solar heating. This synoptic setup—mild maritime air modified by cooler continental influences and widespread cloud cover—suppresses daytime warming compared with clearer conditions earlier in the week. Recent model updates have shown little shift, keeping the 13–15°C band dominant while assigning low probability to extremes outside that range. With the date only two days away, resolution will hinge on final observational data from Helsinki stations; traders are weighting the tight cluster of model guidance and historical September norms for the region.

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 24 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.**Current forecast consensus from numerical weather prediction models positions 14°C as the most probable daily high for Helsinki on September 24.** Multiple runs, including those referenced by the Finnish Meteorological Institute and global ensembles, indicate a high near 14–15°C (roughly 57–59°F) under overcast skies with northeasterly flow, patchy rain or showers, and limited solar heating.
