New 30 Year Climate Normals (1991 - 2020)

The 30-year normals are updated once every 10 years by the National Centers for Environmental Information (NCEI). Some of the popular variables calculated include: temperature, precipitation and snowfall that are listed here for our primary climate stations of Buffalo, Rochester and Watertown. The data displayed here is from NCEI which is the official source of climate normals. Further information on the new climate normals, including additional locations across the country can be found from NCEI at this weblink.
