Latest forecasts from the Finnish Meteorological Institute and supporting models such as Foreca and Yr.no project a daytime high of 19–20°C for Helsinki on August 28 under partly cloudy skies with light to moderate southerly winds and negligible precipitation risk. This consensus, driven by stable high-pressure conditions and typical late-August Baltic Sea moderation, positions 20°C as the leading outcome at 53.5% implied probability, with 21°C capturing upside model variance at 27.5%. Historical August averages near 18°C provide climatological context, while minor inter-model spreads in maximum temperatures explain the modest probability assigned to 19°C. No significant shifts have emerged in the past 24 hours, keeping near-term resolution dependent on final observational data.

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 28 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
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
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 such as Foreca and Yr.no project a daytime high of 19–20°C for Helsinki on August 28 under partly cloudy skies with light to moderate southerly winds and negligible precipitation risk.
