Climate of New York
Seasonally, summer-like conditions prevail from June to early September statewide, while areas in far southern New York and New York City have summer conditions from late May through late September. Cold-air damming east of the Appalachians leads to protracted periods of cloud cover and precipitation east of the range, primarily between the October and April months. Winter-like conditions prevail from November through April in northern New York, and from December through March in southern New York. On average, western New York is much cloudier than points south and east in New York, much of it generated from the Great Lakes. Greenhouse gas emission is low on a per capita basis when compared to most other states due to the extensive use of mass transit, particularly across New York City. The significant urbanization within New York city has led to an urban heat island, which causes temperatures to be warmer overnight in all seasons.
