Temperatures and cloud cover
Onet's daily forecast for Białystok puts the maximum temperature on 20 October 2026 at 13 °C (Białystok - jakiej pogody możemy się spodziewać 20.10.2026? – Onet). The outlet says the temperature people will actually feel, which takes into account humidity, wind and precipitation, is lower, at 11 °C. Clouds are expected to cover 95 percent of the sky.
How the feels-like figure works
The portal explains that the perceived temperature combines the actual reading with humidity, wind speed and precipitation. In winter, strong wind and high humidity make the air seem colder than the thermometer shows. In summer, the opposite holds: still air and high humidity produce a muggy feeling that often comes before rain.
