Current forecasts from the Finnish Meteorological Institute and ECMWF ensembles position a daily maximum near 20°C for Helsinki on August 18, 2026, under stable high pressure, light southerly flow, and limited cloud cover that supports modest warming above late-August norms. Baltic Sea moderation and declining solar insolation keep values tightly clustered between 19–21°C, with minimal risk of stronger warm advection or radiative cooling that would shift the outcome lower. This narrow model spread and historical climatology—average highs of 19–20°C—drive the market’s heavy weighting toward 20°C, while residual uncertainty in boundary-layer mixing and sea-surface feedbacks sustains smaller probabilities for 19°C or 21°C ahead of official resolution.

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 18 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.
