Recent forecasts from the Finnish Meteorological Institute and ensemble models indicate a daytime maximum near 21–22 °C in Helsinki on August 4 under light southwesterly flow and variable cloud cover. This aligns with early-August climatology showing mean highs of 19–20 °C at Helsinki-Vantaa, with the market-implied 45 % probability on 22 °C reflecting modest warm advection from the Baltic Sea and limited daytime heating. Updated model runs show no significant synoptic shift that would push readings to 23 °C or higher or drop them below 21 °C, keeping tail outcomes at single-digit odds. Official hourly observations at the airport station on August 4 will determine resolution.
