**Current forecast consensus from the Finnish Meteorological Institute and supporting models centers on a daily maximum near 23°C for Helsinki on June 28, driven by moderate northwesterly flow, increasing cloud cover, and scattered showers that limit daytime heating.** Ensemble guidance shows limited spread, with most solutions keeping highs in the low-to-mid 20s Celsius amid typical early-summer Baltic Sea influence and no strong high-pressure ridge to promote stronger insolation or advection of warmer air masses. Historical June climatology (average highs ~19–20°C) places these values slightly above normal but well below heatwave thresholds, while the close clustering of market-implied probabilities around 23–25°C reflects genuine uncertainty in exact peak timing and local boundary-layer mixing rather than divergent large-scale signals. Updated model runs and official briefings over the next 48 hours will refine whether modest clearing allows a brief push toward 25°C or if persistent moisture caps the outcome nearer 23°C or below.
