Recent forecasts from the Finnish Meteorological Institute and European models indicate maximum temperatures near 19–20°C in Helsinki on August 13, consistent with mid-August climatology and stable high-pressure conditions. Ensemble guidance shows limited day-to-day variability, with mostly cloudy skies and light winds suppressing stronger warming or cooling. This positions 19–21°C outcomes as the market focus, reflecting typical model spread in maximum temperature resolution rather than any anomalous atmospheric setup. Updated runs through August 11 maintain this narrow range without signals of heat advection or significant frontal passages that could shift probabilities.

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 13 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.Recent forecasts from the Finnish Meteorological Institute and European models indicate maximum temperatures near 19–20°C in Helsinki on August 13, consistent with mid-August climatology and stable high-pressure conditions.
