Latest forecasts from the Finnish Meteorological Institute show Helsinki-Vantaa Airport temperatures peaking near 21°C on August 5 under partly cloudy skies and light southwesterly winds, aligning with the market's leading 44% implied probability for that outcome amid tight competition with 22°C. Regional high pressure and Baltic Sea moderation are limiting daytime warming, keeping maxima close to the long-term August average of 19–20°C while model consensus leaves room for minor upward revisions if afternoon insolation strengthens. Official station readings will finalize resolution by midnight local time.
