Current forecasts from the Finnish Meteorological Institute and other models indicate daytime highs in Helsinki on August 21, 2026, centered around 19–20°C, aligning with the closely matched market-implied odds for those outcomes. Late-August cooling from reduced solar insolation and moderating Baltic Sea air masses typically cap peaks near seasonal averages of 18–20°C, while variable cloud cover, wind patterns, or isolated showers introduce uncertainty in the exact maximum. Ensemble model spreads and recent pressure system shifts explain the tight contest between 19°C and 20°C, with lower probabilities for 21°C or cooler reflecting limited warming potential before resolution.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 21 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Helsinki Vantaa Airport Station, available here: https://www.wunderground.com/history/daily/fi/vantaa/EFHK.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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.Current forecasts from the Finnish Meteorological Institute and other models indicate daytime highs in Helsinki on August 21, 2026, centered around 19–20°C, aligning with the closely matched market-implied odds for those outcomes.
