Official forecasts from the Finnish Meteorological Institute indicate a daytime maximum of 16°C for Helsinki on June 1 under stable high-pressure conditions, light winds, and minimal cloud cover that limit further warming. This aligns closely with early-summer climatology, where average highs reach 16–19°C, and recent model runs show little divergence. The market's near-certain outcome at 16°C reflects this consensus in observational data and short-range numerical weather prediction. Scenarios that could shift the peak include unforecasted warm advection or measurement revisions at official stations, though current guidance assigns low probability to temperatures deviating beyond 15–17°C.
