Current forecasts from the Finnish Meteorological Institute and supporting models project a daytime high near 20–21°C for Helsinki on August 2, 2026, consistent with early-August climatology of roughly 20°C. Ensemble spreads and minor model differences around potential afternoon warming under partly sunny conditions support the market's leading outcomes at 21–23°C, with 22°C holding the plurality at 50.5%. Recent model runs have shown limited upward revisions, keeping probabilities for 24°C or higher below 4% while assigning negligible weight to sub-20°C readings. Traders appear to price in typical forecast uncertainty ranges for a two-day horizon, where small shifts in cloud cover or wind could still alter the observed maximum before resolution.
