Webster is situated near Lake Ontario. The lake has a significant impact on the city's weather. To the east of Webster lies a hilly terrain. This landscape combination affects the atmospheric pressure. The lake cools or warms the air, while the hills influence the air flow.
The surrounding hills force air to rise, cool, and condense, resulting in precipitation. The lake's water temperature also regulates the air temperature. During winter, the lake's warmer water heats the air, leading to lake-effect snow.
