Staré Město Weather in September

About Staré Město in September

Staré Město's dense medieval street network with narrow lanes and heavy stone buildings creates a pronounced urban heat island at the heart of the Vltava basin. Proximity to the river brings frequent morning fog in autumn and winter, while the lack of green space and poor ventilation keep summer nighttime temperatures 2–3°C above the city average.
