Humid continental climate worldwide

Generally summers of New York have a humid continental climate (Koppen Dfa in some central and southern lowlands and the Hudson Valley, Dfb in the rest of the upstate). Weather in New York is heavily influenced by two continental air masses: a warm, humid one from the southwest and a cold, dry one from the northwest. A cool, humid airflow from the North Atlantic also has an effect on weather in the state, albeit to a lesser extent than the continental ones. Many continental frontal boundaries move across New York, with storm systems moving north along the coast, often affecting the southern areas of the state. In places like Huntington on Long Island, the climate is warmer than places up north, like Ticonderoga, where both the latitude and altitude are higher. In Huntington, the average high July temperature is 83 °F (28 °C), while in Ticonderoga, the average high in July is 81 °F (27 °C), which are very close, but in the summer the ocean will have a cooling effect on the air. The average high January temperatures, however, are much farther apart.

The winters are long and cold in the Plateau Divisions of the state. In the majority of winter seasons, a temperature of −13 °F (−25 °C) or lower can be expected in the northern highlands (Northern Plateau) and 5 °F (−15 °C) or colder in the southwestern and east-central highlands (Southern Plateau). The Adirondack region records from 35 to 45 days with below zero temperatures, in normal to severe winters.^{[citation needed]} Much of Upstate New York, particularly Western and Central New York, are typically affected by lake-effect snows. This usually results in high yearly snowfall totals in these regions. Winters are also long and cold in both Western and Central New York, though not as cold as the Adirondack region. The New York City metro area, in comparison to the rest of the state, is milder in the winter (especially in the city itself, which averages near or slightly above freezing). Thanks in part to geography, its proximity to the Atlantic and being shielded to the north and west by hillier terrain, the New York metro area usually sees far less snow than the rest of the state. Lake-effect snow rarely affects the New York metro area, except for its extreme northwestern suburbs. Winters also tend to be noticeably shorter there than the rest of the state.^{[citation needed]}

The summer climate is cool in the Adirondacks, Catskills and higher elevations of the Southern Plateau. The New York City area and lower portions of the Hudson Valley have hot summers by comparison, with some periods of high, uncomfortable humidity. The remainder of New York State enjoys pleasantly warm summers, marred by only occasional, brief intervals of sultry conditions. Summer daytime temperatures usually range from the upper 70s to mid 80s °F (25 to 30 °C), over much of the state.

New York ranks 46th among the 50 states in the amount of greenhouse gases generated per person. This efficiency is primarily due to the state's higher rate of mass transit use.

New York's highest recorded temp. is 108 °F (42 °C). This happened during the month of July. The coldest temperature recorded in New York took place in Old Forge on February 17 , 1979, with a temperature of −52 °F (−47 °C).
