Trader consensus on Polymarket heavily favors a Helsinki high of 7°C (40%) or 8°C (32.5%), reflecting the latest Finnish Meteorological Institute forecast updated midday April 3 showing a 15:00 peak near 7°C amid persistent overcast skies, light winds (2-3 m/s), and scattered drizzle limiting insolation. AccuWeather aligns with a 7°C maximum under 96% precipitation odds and cloudy conditions from a cool maritime air mass. The narrow split stems from ensemble model discrepancies—ECMWF variants suggest minor afternoon cloud thinning could push 8°C, while GFS emphasizes thicker decks capping at 7°C—highlighting short-term boundary layer uncertainty. Observations through evening will confirm, with climatological early-April norms (4-7°C) reinforcing low odds for extremes.
