Trader consensus on Polymarket prices 14°C as the leading outcome at 39% implied probability for Helsinki's highest temperature on May 14, driven by the Finnish Meteorological Institute's (FMI) early-morning forecast update projecting afternoon peaks near 12°C at central Kaisaniemi station under overcast skies and southeast winds moderating solar heating. This reflects a cool mid-May air mass, cooler than the 14.5°C historical average high, yet traders factor in forecast uncertainty from ECMWF and GFS model ensembles showing potential for 13-15°C if cloud breaks allow greater insolation during peak heating hours around 2-4 PM. Real-time observations from the resolving Helsinki-Vantaa Airport station, typically 1-2°C cooler than city center, will clarify as the day progresses.
