**Forecast models indicate a minimum temperature in Helsinki on August 25 likely falling between 9–13°C under partly cloudy skies and light northerly winds, with radiative cooling favored overnight after a high near 17–19°C.** Current guidance from sources including the Finnish Meteorological Institute, Foreca, and yr.no shows lows clustered around 9–13°C, consistent with late-August climatology where the 1991–2020 average minimum is 12.5°C. The close market-implied odds around 43–47.5% for 7°C or below versus 12–14°C reflect genuine uncertainty in short-range model runs—particularly how quickly high pressure builds and whether skies remain clear enough for enhanced nocturnal cooling versus residual cloud or slightly stronger winds that could hold temperatures higher. Updated model consensus and any new observational data on cloud trends or wind fields over the next 48 hours will be key drivers for shifts in trader positioning.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Helsinki Vantaa Airport Station in degrees Celsius on 25 Aug '26.
The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=efhk
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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.**Forecast models indicate a minimum temperature in Helsinki on August 25 likely falling between 9–13°C under partly cloudy skies and light northerly winds, with radiative cooling favored overnight after a high near 17–19°C.**
