Latest forecasts from the Finnish Meteorological Institute and supporting models indicate a daytime high near 19°C for Helsinki on August 25 under partly cloudy skies with moderate northerly winds and limited moisture. This aligns with late-August climatology, where highs typically decline from the mid-20s earlier in the month toward 18–19°C. The tight split between 19°C and 20°C outcomes reflects minor model divergence on afternoon cloud cover and boundary-layer mixing; brief clear spells could add 1°C of insolation-driven warming, while persistent stratiform clouds or stronger winds would cap readings at 18°C. Resolution depends on the official daily maximum recorded at the Helsinki-Vantaa station.

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 25 Aug '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
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.Latest forecasts from the Finnish Meteorological Institute and supporting models indicate a daytime high near 19°C for Helsinki on August 25 under partly cloudy skies with moderate northerly winds and limited moisture.
