Recent forecasts from the Finnish Meteorological Institute and other models indicate a stable high-pressure regime over southern Finland through August 28, supporting daytime highs near 19–20°C under partly cloudy skies and light southerly winds. This setup favors modest solar heating without strong advection of warmer or cooler air masses, keeping the distribution centered on late-summer climatology. Ensemble spreads in short-range models introduce uncertainty around cloud timing and boundary-layer mixing, which can shift peak readings by 2–3°C and explain the broad, evenly matched market-implied probabilities across bins. Minor shifts in wind direction or increased marine influence from the Baltic could readily differentiate outcomes between the 17–19°C and 20–22°C ranges.
