Climate chart - Niagara Falls (New York)
In the Niagara Falls area, the climate is continental, with very cold winters and warm summers. Although we are on the 43rd parallel, the winter weather is cold because the North American landmass cools down a lot in this season, and outbreaks of polar air masses are frequent, to the point that the waterfalls can even freeze partially on colder winters.
At Niagara Falls International Airport, in New York State, the daily average temperature ranges from -3.6 °C (25.5 °F) in January to 22.3 °C (72 °F) in July. Here are the average temperatures.

Precipitation amounts to about 880 millimeters (34.7 inches) per year and is well distributed over the seasons. In fact, weather fronts can affect this area in every month because of the continual clash between warm and cold air masses; in summer, when they are less frequent, thunderstorms can erupt in the afternoon, adding more rain, so much so that summer is as rainy as autumn, at least in quantity. Here is the average precipitation.

In winter, from late November to March, precipitation occurs mainly in the form of snow (there are on average around 50 days with snowfall per year). Snow normally covers the ground from mid-December to early March. In a year, about 185 centimeters (72 in) of snow fall; sometimes it can snow already in October, and in spring, still in April. In winter, real snow storms can occur, accompanied by gusts of blizzard.
On the coldest nights of the year, the temperature typically drops to around -18 °C (0 °F). In February 2015, it dropped to -25 °C (-13 °F), while in January 1996, it dropped to -26 °C (-15 °F).
However, given the unstable weather, the temperature can exceed freezing (0 °C or 32 °F) even in winter, and in these periods, snow can melt and it can even rain.
Spring, from mid-March to May, is an unstable season, characterized by sudden changes in temperature: initially cold in March, with frequent snowfalls and frosts, it advances gradually, with the first warm days but also the return of cold weather; it is still quite cold on average in April, and becomes mild in May, when the first afternoon thunderstorms occur.
Summer, from June to August, is warm and quite sunny, although there is a moderate amount of cool and cloudy days, with some chance of rain, while in fine weather, thunderstorms can erupt in the afternoon. Sometimes, hot periods can occur, with highs around 34/35 °C (93/95 °F). In July 2005, the temperature reached 36 °C (97 °F).
Autumn, from September to mid-November, is initially pleasant, with many sunny days, during which the temperature exceeds 25 °C (77 °F): these periods, called Indian summer, occur in September, but sometimes also in October. As the weeks pass, however, the temperature decreases rapidly, weather disturbances become more frequent, and the first cold days occur.
The amount of sunshine in the Niagara Falls is overall good in summer, and acceptable in May and September. It is not high in the other months, and it's quite scarce from November to February, when the sun shows up rarely.

The falls are formed by the confluence of Lake Erie and Lake Ontario, at the border between the US state of New York and the Canadian province of Ontario. There are two waterfalls: the Horseshoe Falls, the largest ones, at the border between Canada and the United States, and the smaller American Falls, a short distance from the former and entirely in the U.S. territory. The two falls are separated by Goat Island. The American Falls are actually divided into two, since at their side there are the smaller Bridal Veil Falls, which are separated from them by Luna Island.
The waters flow northwards, in fact, Lake Erie, in the south, is located at about 170 meters (555 feet) above sea level, while Lake Ontario, in the north, is located around 100 meters (325 ft) below. However, the actual jump is about 30 meters (100 ft) in the American Falls (at least compared to the rocks below) and approximately 52 meters (170 ft) in the Horseshoe Falls.
The large cities closest to the falls are Buffalo, NY, Usa, and Toronto, Ontario, Canada.
Lake Ontario and Lake Erie are very cold in winter, when the waters approach the freezing point, while in summer, they become almost acceptable for swimming, at least for those who do not suffer from the cold, especially in August, when they reach 22 °C (71.5 °F). Here are the average water temperatures of Lake Erie in Buffalo.

January | 3 | 38 | February | 2 | 36 | March | 2 | 36 | April | 3 | 38 | May | 7 | 45 | June | 14 | 58 | July | 20 | 69 | August | 22 | 71 | September | 20 | 67 | October | 14 | 58 | November | 10 | 49 | December | 5 | 42 | Year | 10.3 | 50.6 |
Best Time
The best time to visit the Niagara Falls runs from mid-May to late September. In midsummer, in July and August, not only the waterfalls are very crowded, but also there may be hot and muggy days, so this period can be excluded if you cannot stand the heat (although the heat can be positive when you approach the waterfalls and get wet from the spray).
You can therefore choose May and September. In May and early June, it can still be a little cold, and in any case, you have to take into account the possibility of rain and of temperature swings.
In the first half of October, it can be cold, but you can admire the trees taking on their spectacular autumn colors, while in spring, you can see flowers blooming in the nearby botanical garden.
In winter, during the coldest periods, you can admire the spectacle of the partially frozen waterfalls.
