Trader consensus on Polymarket has locked in a near-100% implied probability for Helsinki's highest temperature reaching exactly 7°C on April 26, driven by Finnish Meteorological Institute (FMI) observational data and hourly forecasts showing a midday peak of 7°C at stations like Viikki, followed by a steady drop to 4°C amid persistent northwest winds of 5-9 m/s and partly cloudy conditions. Current late-evening readings align with this, as solar heating diminishes post-15:00 with sunset approaching around 20:30. April climatology supports such cool snaps, with historical late-month highs averaging 7-8°C under northerly flow. Realistic challenges include an improbable sudden wind lull and clearing skies enabling a brief 1°C spike before resolution based on FMI's Helsinki-Vantaa Airport station data, but model consensus indicates negligible risk.
