Trader consensus on Polymarket reflects profound uncertainty for Helsinki's highest temperature on April 4, with market-implied probabilities evenly split at 25.5% across outcomes from 0°C or below to 9°C, and just 1.5% for 10°C or higher. The Finnish Meteorological Institute's latest forecast points to a daytime high near 3°C amid a cooling trend from recent 6-7°C readings, driven by westerly winds shifting northerly, increased cloud cover, and 50% precipitation odds that could suppress peaks. Prediction intervals (50-80%) span 0-6°C, capturing springtime variability from Baltic Sea moderation and passing fronts; ECMWF and GFS ensembles show similar spreads due to unresolved frontal timing. Historical early-April highs average 5°C with a 2-3°C standard deviation, underscoring potential for outliers, though 10°C+ remains climatologically rare. Hourly FMI updates will sharpen resolution tomorrow.
