Forecast
The barometric pressure in Rochester, New York fluctuates throughout the year. It changes with the weather patterns and seasons. Pressure systems from the surrounding regions influence the city's pressure.
Rochester is situated on the southern shore of Lake Ontario. The lake's proximity affects the local climate. The city's landscape is relatively flat and low-lying. This allows air masses to move freely and influence the pressure.
The surrounding hills and mountains to the south and east create a rain shadow effect. This blocks some air masses from reaching the city. As a result, Rochester's pressure is affected by the movement of air around these natural barriers.
