Current short-range forecasts from ECMWF, GFS, and regional models indicate a minimum temperature in Helsinki on October 10 likely between 4–6 °C under mostly cloudy skies and moderate northwest winds, limiting radiative cooling. A recent shift to cooler northerly flow after a milder period has lowered expected overnight lows relative to the 5.2 °C historical average, yet persistent cloud cover and light precipitation reduce the chance of sharp drops toward freezing. Ensemble spreads show limited support for sub-zero readings or daytime maxima pushing the daily minimum above 10 °C, keeping those binary outcomes near even odds while concentrating probability on single-digit values. Updated model runs and official Finnish Meteorological Institute guidance through the evening of October 9 will refine the precise minimum ahead of market resolution.
