Forecast models for Helsinki on August 22 indicate a daily minimum near 12–13°C driven by moderate southerly flow, increasing cloud cover, and light winds that limit nocturnal radiative cooling under a lingering warm air mass. Official guidance from the Finnish Meteorological Institute and ensemble runs highlight modest uncertainty in exact overnight lows, with potential for greater cooling if clearer skies develop ahead of a weak front. Historical late-August climatology shows typical minima of 10–13°C, providing context for why market-implied odds cluster tightly around 11–15°C outcomes while assigning notable probability to cooler thresholds amid ongoing model variability. Updated short-range forecasts expected later today could refine these estimates before resolution.

This market will resolve based on the lowest 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 lowest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 22 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.
