**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.
