Central Lakes - NY10
At a first glance, the climate of New York’s Central Lakes (Finger Lakes) region is generally representative of humid climates in the northeastern United States, but within the division, topography plays a large role, leading to a wide range of microclimates. Most importantly for the region, the lakes themselves moderate temperature very nearby, allowing for robust wine grape production that would otherwise be less favorable. The lake effects result in an affectionately named “banana belt”, particularly on the southeastern shore of Seneca Lake. The relative local climate moderation is similar to that experienced in other specific parts of the Great Lakes region, such as on the Leelanau Peninsula of Michigan, an area known for tart cherry production. The division commonly sees cold air masses approach from the west and north. As with much of the Great Lakes region, weather patterns can vary greatly over the course of a week, especially during the fall and spring. Summer temperatures are seldom depressing to humans, and summer nights are typically cool enough to provide relief from mid-day heat. Winters are cold, but not usually extreme or particularly dangerous. Rain and snow are typically delivered by air masses from the Gulf of Mexico or cyclonic systems along the Atlantic coast. Precipitation is relatively well-distributed throughout the year, with most falling during warmer months and in thunderstorms. Snowfall is highly variable based on elevation.
In partnership with the Midwest Regional Climate Center and the Office of the Michigan State Climatologist, GLISA has developed summaries of the observed historical climate for NOAA U.S. Climate Divisions within the Great Lakes basin. Each summary includes an overview of temperature and precipitation to help guide local-level climate adaptation decisions.
