Recent Finnish Meteorological Institute forecasts and supporting European model runs point to a maximum of 19–21°C in Helsinki on August 28, with 20°C emerging as the narrow consensus under southeasterly flow and partly cloudy skies. Milder maritime air advection and modest daytime heating in late-summer conditions support this range, while minor differences in cloud cover, timing of any weak frontal passage, and boundary-layer mixing explain the tight spread among 19°C, 20°C, and 21°C outcomes. Traders are weighting the most recent deterministic and ensemble guidance, which show limited variability but acknowledge typical short-range forecast uncertainty in high-latitude summer temperatures.

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.
