Official forecasts from the Finnish Meteorological Institute and other agencies indicate a maximum of 15–16°C in Helsinki today under overcast skies, light rain, and northerly winds that limit daytime warming. These conditions align with climatological cooling trends in late August, where average highs drop toward 17°C, but current atmospheric setup—persistent cloud cover and onshore flow—suppresses peaks below recent baselines. Model consensus shows little deviation, with only marginal upside risk if breaks in clouds occur. Market-implied odds heavily favor 15°C as the most likely outcome given the stability of these inputs ahead of final observations.
