Winter, from late November to early March, is very cold.
On average, there are 49 icing days (that is, on which the air temperature does not go above freezing), and that usually happens from November through April.
On average, 242 centimeters (95.4 in) of snow fall per year. It usually snows from October through April, although snow normally covers the ground from mid or late December to early March. The heaviest snowfall in one day occurred in December 1995, when 86 cm (34 in) of snow fell. Buffalo is a particularly snowy city due to the so-called lake-effect snow, whereby the cold wind from Canada is charged with humidity as it passes over the lake. This phenomenon occurs more easily in the first part of winter, since the lake often freezes at the end of January and in February. Furthermore, the phenomenon is more evident in the part of the lake facing north-west or west, therefore the one that goes from the eastern part of Cleveland to Buffalo.
Cold waves are intense, in fact, the temperature drops below -18 °C (0 °F) almost every year. The record cold, -28 °C (-18.5 °F), occurred in February 1961.
However, there may be short periods when the temperature exceeds 10/12 °C (50/54 °F) even in the middle of winter.
Summer, from June to August, is hot and sunny, although thunderstorms can break out in the afternoon. In the afternoon, the refreshing breeze blows from the lake.
On average, there are only 3 days with a maximum temperature equal to or above 32 °C (90 °F), and that usually happens from May through September. The record is 36.7 °C (98 °F), set in August 1948 and July 2020.
Spring and autumn, from mid-March to May and from September to mid-November, are contrasted seasons, with fairly frequent rains and sudden changes in temperature. However, there are also stable and pleasant periods.
On average, there are around 2,205 sunshine hours per year. The sun shines a quarter of the time in December and two thirds of the time in July. Here are the average sunshine hours per day.
