Trader consensus on Polymarket overwhelmingly favors 12°C as Helsinki's highest temperature on May 6, reflecting observational data from Helsinki-Vantaa Airport station— the market's resolution source—peaking near 12°C midday amid northerly winds and partial cloud cover. Finnish Meteorological Institute hourly forecasts confirm this positioning, projecting no further warming with evening temperatures dropping to 7–10°C under a stable post-frontal airmass, corroborated by ECMWF and GFS ensemble model agreement on subdued solar heating. Early May climatology supports this, with historical highs averaging 11–13°C. Realistic challenges are minimal this late in the day, though unexpected prolonged clearing could marginally boost readings by 1–2°C before sunset.
