Niagara Falls weather is a blend of East Coast and Midwest weather. Being near the falls, you can expect mist in the air that will keep the area a little cooler. Weather in Niagara Falls is much milder than you would expect, much in part because of Lake Ontario. On average, spring and summer months range in temperatures of 60 - 80 degrees Fahrenheit. In the winter, days tend to be just about freezing. Niagara Falls seldom gets snow, but if it does, you would find it in January, which is the coldest month for Niagara Falls weather.
