Recent official forecasts from the Finnish Meteorological Institute and supporting models center the daytime maximum in Helsinki near 20–21°C on August 8, 2026, under moderate southwesterly flow, partly cloudy skies, and light precipitation that limits peak heating. This consensus drives the market's heavy weighting toward 21°C (62.5% implied probability) and 20°C (23.0%), consistent with early-August climatology where average highs hover around 20°C. Typical model spread of ±1–2°C, combined with variable wind patterns and localized insolation, supports smaller probabilities for 22°C (12.5%) while rendering outcomes above 23°C or below 19°C unlikely given current observational trends and stable synoptic conditions.

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 8 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.
