SSnow cover extent (SCE) over Northern Hemisphere (NH) lands for the August 2024–July 2025 period averaged 23.9 million sq. km. This is 1.0 million sq. km. less than the 1991-2020 mean and 1.1 million sq. km below the full period of record mean (Table 1). Thus, this recent snow season ranks as having the 56th most extensive (3rd least extensive) cover in the 58-year period of record. Monthly SCE during the season ranged from 45.5 million sq. km. in February 2025 to 2.6 million sq. km. in August 2024. North America (NA) annual SCE ranked 50th most extensive in 58 years and Eurasia (EUR) 53rd most extensive.﻿
