The latest Finnish Meteorological Institute forecast, updated April 14, projects Helsinki's highest temperature on April 15 reaching 15°C around 3 p.m. local time under clear skies, light winds of 6 m/s (gusts to 9 m/s), and less than 10% precipitation chance, driving trader consensus to 74.5% implied probability for 15°C or higher. This aligns with a persistent high-pressure ridge fostering dry, sunny conditions and above-normal April temperatures—historical averages hover around 8°C—following April 14 evening observations near 10°C after daytime peaks near 14°C per prior market resolution. Ensemble model consensus from ECMWF and GFS supports mild advection, though slight shortfalls to 14°C (18.5% odds) remain possible due to cloud variability or stronger winds limiting solar heating; official measurements at Helsinki-Vantaa resolve the market post-midnight April 16.
