Recent ECMWF and GFS model runs indicate a cool, cloudy regime over southern Finland with southwesterly flow and widespread stratiform cloud cover limiting diurnal heating for September 18. This setup favors afternoon maxima near 15–16 °C, consistent with the market’s tight clustering around those outcomes and historical mid-September climatology of roughly 15 °C. Persistent low-level moisture and light precipitation further cap surface warming, while the Baltic Sea’s thermal inertia prevents sharper swings. Ensemble spread remains modest, with only minor differences in cloud timing or wind speed that could nudge the peak by 1 °C either way; updated high-resolution runs and FMI observations over the next 48 hours will refine the precise maximum.

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.
