Latest meteorological model consensus from sources including the Finnish Meteorological Institute and UK Met Office points to a daytime high near 21–22°C for Helsinki on August 16, driven by variable cloud cover, light winds, and limited solar heating amid typical late-summer conditions. Ensemble spreads reflect uncertainty in exact peak timing and any brief clear intervals that could allow modest warming, while historical climatology shows mid-August maxima averaging around 20°C with declining solar insolation. Trader sentiment clusters on these outcomes as fresh model runs reinforce the narrow range, with lower probabilities assigned to outliers beyond 23°C due to suppressed instability and the unlikelihood of significant warm advection.

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 16 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.Latest meteorological model consensus from sources including the Finnish Meteorological Institute and UK Met Office points to a daytime high near 21–22°C for Helsinki on August 16, driven by variable cloud cover, light winds, and limited solar heating amid typical late-summer conditions.
