Trader consensus on Polymarket has locked in a 100% implied probability for a highest temperature of 16°C in Helsinki on May 12, driven by Finnish Meteorological Institute (FMI) observations at the official Helsinki-Vantaa Airport station, which recorded a midday peak of 16°C before cooling to 10-12°C amid persistent cloud cover, southerly winds of 5-6 m/s, and scattered light precipitation limiting insolation. ECMWF and GFS forecast models align, projecting no further diurnal warming as the day progresses into evening. This fits May climatology averages of 14-15°C highs. Realistic challenges include a rare post-finalization data revision upward from microclimatic sensor discrepancies or improbable clearing for a late-afternoon surge, with FMI bulletins expected post-midnight to confirm resolution via Wunderground archives.
