Recent forecast model runs from agencies including the Finnish Meteorological Institute and ECMWF indicate a mild late-summer pattern over southern Finland, with a weak frontal system bringing light showers and moderate southwesterly flow that limits daytime heating. This setup supports maximum temperatures clustering around 20–22 °C on August 16, aligning with the market’s near-even split between those two outcomes. Sea-surface temperatures in the Gulf of Finland remain near seasonal norms, providing modest moisture and moderating extremes, while ensemble spreads show limited potential for either stronger high pressure (favoring 23 °C+) or increased cloud cover (capping at 19–20 °C). Updated model guidance expected within 24 hours will narrow the remaining uncertainty ahead of market resolution.
