Trader consensus on Polymarket favors a highest temperature of 14°C in Helsinki at 47.5% implied probability, reflecting the Finnish Meteorological Institute's (FMI) latest early-May 14 forecast update showing daytime peaks around 11–12°C amid persistent southwesterly winds at 6 m/s and scattered clouds, with feels-like temperatures 3–5°C lower due to gusts and humidity near 80%. This positioning stems from a recent low-pressure system over the Baltic Sea delivering cool maritime air, capping solar heating after below-average temps in the prior 48 hours (highs of 10–13°C); climatological May 14 averages hover at 14°C, but current model ensembles like HARMONIE-AROME indicate limited intensification potential. Uncertainty persists in afternoon cloud breaks, with real-time Helsinki-Vantaa observations through 18:00 local time determining the official max under Saffir-Simpson-irrelevant integer rounding; next FMI update expected midday could refine odds as skin-in-the-game traders weigh ±2°C forecast variance.
