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 model runs from European forecasting centers indicate a mild high of 21–23°C for Helsinki on August 16, with light southwesterly flow and variable cloud cover limiting daytime heating. This aligns with mid-August climatology, where average maxima hover near 20°C, though brief sunny intervals could push readings toward the upper end of that range. Ensemble guidance shows low spread, with minimal risk of stronger advection or clearing that would support 24°C or higher, while stable boundary-layer conditions make sub-20°C outcomes unlikely. Updated short-range forecasts tonight and tomorrow morning will refine exact peak timing ahead of market resolution.
