The latest Finnish Meteorological Institute forecast, updated early on April 15, projects Helsinki's highest temperature on April 16 at 9°C around 15:00 local time under overcast skies, light easterly winds of 3-5 m/s, and low precipitation risk, reflecting a cooling trend from yesterday's 11.6°C observation and today's expected 13°C peak. Yet trader consensus favors milder outcomes—30.5% implied probability for 13°C or higher, 22% for 12°C, 16% for 11°C—due to ensemble spreads in ECMWF and GFS models, where some members depict reduced cloud cover boosting insolation and highs to 12-13°C amid lingering mild air advection. Key differentiators include cloud opacity suppressing daytime heating versus potential high-pressure reinforcement; new overnight runs and morning soundings could tip the balance before peak afternoon heating. April climatology averages 8-10°C highs, underscoring above-normal but volatile spring conditions.
