Latest forecast models from the Finnish Meteorological Institute and ECMWF consensus show Helsinki's August 17 high temperature most likely reaching 20–21°C, reflecting a stable high-pressure ridge with modest southerly flow and limited daytime heating under partly cloudy skies. The near-even market split between these outcomes captures genuine uncertainty from small differences in predicted cloud cover and boundary-layer mixing, which can swing the peak by 1°C. Historical August averages near 21°C provide baseline context, while ensemble spreads highlight how minor shifts in the 12–18 UTC window could favor either reading. Final resolution will depend on official synoptic observations at the Helsinki-Vantaa station.

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 17 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.
