Current forecasts from the Finnish Meteorological Institute and ensemble models indicate overnight lows in Helsinki on September 29 near 11–12°C under southerly flow and partly cloudy skies, well above the 7.2°C climatological average. Trader balance between sub-6°C and 16°C+ outcomes reflects model sensitivity to variables including radiative cooling under clearer breaks, wind-driven mixing from the Baltic, and potential shifts in a weak frontal boundary. Short-range runs show limited spread around the central tendency, though modest revisions in cloud cover or advection could alter the minimum by several degrees before resolution.
