Recent forecast models from agencies including the Finnish Meteorological Institute point to a September 6 high near 15°C in Helsinki, driven by persistent northwest winds and partly cloudy conditions that limit daytime warming. This places the outcome squarely in line with early-September climatology, where the 1991–2020 average high is 17.1°C but recent model runs show modest cooling from a stable high-pressure ridge. Traders have priced 15°C as the clear favorite at 63.5% implied probability, with 16°C and 14°C as secondary options, reflecting tight consensus around observed sea-surface temperatures in the Baltic and minimal model spread for the 24-hour period. No significant warm-air advection or clear-sky radiative heating is expected to push readings higher before sunset.

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.
