Weather & Climate in Niagara Falls

Niagara Falls area enjoys four seasons of differing climate:


In the spring, the daily high temperatures in March, April and May range from 5° to 19° degrees Celsius (41° – 66° degrees Fahrenheit). Nightly temperatures range from -3° to 8° degrees Celsius (26º to 46° degrees Fahrenheit). Outdoor camping before mid-May is not advisable. Snowfall season usually ends by mid-April. Lake Erie ice and water temperature may effect surrounding land mass with cooler than normal breezes. Mixed weather patterns prevail.


In the summer, the daily high temperatures in June July and August range from 25° to 21° degrees Celsius (75º to 81° degrees Fahrenheit ). Nightly temperatures range from 14° to 17° degrees Celsius (57° to 63° degrees Fahrenheit). Weather is generally bright and sunny. Rainfall has been sporadic during past several years with near drought conditions. Storms are moderated by nearby Lake Erie and Lake Ontario. Storms are seldom severe. In summer, lake waters are normally cooler than air temperature. Lake Erie’s water temperature normally ranges from 22° to 25° degrees Celsius (73° to 77° degrees Fahrenheit). Cooling lake breezes are often a relief from sometimes hot and humid weather experienced in summer.


In the fall, the daily high temperatures in September, October and November range from 22° to 8° degrees Celsius (72° to 46° degrees Fahrenheit). Nightly temperatures range from 13° to 1° degrees Celsius (55° to 34° degrees Fahrenheit). It is unlikely to snow prior to the end of October. First killing frost and/or snowfall be expected by late October or early November. Mixed weather patterns prevail. Rain and cloudy skies are common.


In the winter, the daily high temperatures in December, January and February range from 2° to -0.9° degrees Celsius (36° to 30° degrees Fahrenheit). Nightly temperatures range from -4.5° to -8.2° degrees Celsius (24° to 17° degrees Fahrenheit). Arctic high pressure generally dominates during the winter months bringing cold and clear days. Snow is moderate. Snow storms are infrequent. Lake effect snowfalls are mainly localized to areas near Buffalo and southward. Lake temperatures are generally warmer than the surrounding air temperatures which sets up dynamics required for lake effect snow. Lake Erie, during extended cold weather will freeze over completely. This eliminates the lake effect snow mechanism but become a less of a temperate moderating factor upon the surrounding land mass. During the past two years, winters have been milder than most, resulting in Lake Erie not freezing over.
