There are four distinct seasons in New York State and each one is enjoyable in its own way. Hot summers and snowy winters are ideal for those looking to experience classic North American seasons and autumn offers leaf-peeping with exploding colors. But if you don't enjoy cold temperatures, a winter trip to New York State should be avoided.

Winter is very cold, with lows in cities like Buffalo going below 20 degrees F (-7 degrees C) from December through February. Snow is common and most areas of the state will have at least one major snowstorm per winter, while the northern and western parts of the state will have many, especially in the mountainous areas of the Catskills and Adirondacks. Average annual snowfall in the state is 25.8 inches.

Spring is unpredictable, with some very cold days in March and snowfall still possible, and cold weather occurring into April. May is warmer, but cool days are still possible. Summer brings average highs in the low 80s Fahrenheit and an average humidity level of 72 percent for the suburbs of New York City, while further north and in the mountains it averages in the low 70s Fahrenheit. Humidity is also much lower in the mountains, providing a nice escape from NYC’s oppressive humidity. Fall brings gorgeous colors thanks to changing leaves and temperatures are mild, especially in September.

Winter also brings winds gusting between the city's skyscrapers—the average daily wind speed stays above 10 miles per hour most of the season.

Summer is one of the most popular times to visit New York State, especially the beaches of Long Island, as well as the Catskill and Adirondack mountains, and the Finger Lakes region, with water sports and hiking popular pastimes.

What to pack: Since it gets pretty hot, shorts, T-shirts, and dresses are necessary. If you’re headed to the shore or a lake, bring a bathing suit, sandals, sunscreen, and a hat. In the mountains, you’ll want a light jacket or sweatshirt and light pants for evenings and nighttime. If you plan on hiking, bring hiking boots or sneakers. Bring a raincoat and umbrella as well, just in case.

Fall in New York State

Expect gorgeous red, yellow, and orange leaves around late September and October; the further north you are the earlier the leaves will change.

Although sometimes a surprise warm day will still occur in October and November, by the end of November the average temperatures drop into the low 50s and 40s Fahrenheit. Rain is also possible in the fall.

Outdoor events still occur into September and October and hiking is popular in the Hudson Valley, Catskills, and Adirondacks. The beaches of Long Island are still fairly full in September, although the ocean might be too cold for some. Early fall also means harvest season in the wine regions of Long Island, Hudson Valley, and the Finger Lakes, and apple picking season in the Hudson Valley and the Catskills.

What to pack: Layers are key in the fall; bring things like jeans, T-shirts, light jackets, and sweatshirts. And be prepared for possible rain with raincoats and umbrellas.

Although winter is a less popular time to visit, there are holiday events, as well as skiing, sledding, and ice-skating. Lake Placid, where the Winter Olympics were twice held is a popular spot for winter sports.
