Current forecasts from the Finnish Meteorological Institute and European models indicate a minimum temperature near 12–14°C for Helsinki on August 22, driven by moderate southwesterly flow, variable cloud cover, and limited nocturnal radiative cooling under partly cloudy skies. Traders assign the highest implied probability to 8°C or below (37.5%) amid uncertainty over potential clearer intervals that could enhance cooling, while clustered probabilities around 11–13°C reflect consensus on typical late-August boundary-layer conditions and recent model consensus showing little intensification of high pressure. Differentiation among close outcomes hinges on precise timing of any showers or wind shifts that alter surface heat retention overnight, with resolution depending on official station readings at the end of the 24-hour period.
