Recent ensemble forecasts from European and global models place Helsinki’s August 7 maximum near 20–22 °C, with tight clustering around 21 °C reflecting modest high-pressure influence and limited daytime heating over the Baltic. Small differences among leading outcomes hinge on variables such as boundary-layer mixing depth, afternoon cloud cover, and local sea-breeze strength, each capable of shifting the peak by 1 °C. With resolution only two days away, updated short-range runs and observed surface observations will narrow the spread before the market settles.
