**Forecast models from sources including the Finnish Meteorological Institute, Foreca, and Yr.no indicate a high of 15–16°C in Helsinki on September 21, 2026, with isolated showers or thunderstorms possible during the day.** This aligns with the market’s strong consensus on 16°C (55.5% implied probability) and 15°C (24%), as a mild air mass under variable winds—shifting northerly later—supports modest daytime warming above the climatological average of roughly 14.4°C. Light precipitation and increasing cloud cover are expected to cap peaks near these levels rather than allowing stronger insolation for 17°C or higher. Recent model runs show limited spread, with no major shifts in steering patterns or upstream systems noted in the past 48 hours, keeping the distribution tightly clustered around 15–16°C while assigning low probability to outliers.

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.
