Himalayas are showing reduced winter snowfall, scientists warn.

Meteorologists report much less winter snow across parts of the Himalayas compared with 1980–2020 averages, and researchers say snow persistence and winter precipitation have fallen in recent years.

Much less winter snow is falling on many parts of the Himalayas, leaving slopes bare in seasons when they are usually snow-covered. Meteorologists and regional researchers report that most winters in the last five years have shown declines compared with 1980–2020 averages. Scientists link the pattern to rising temperatures, faster snowmelt, and changes in the winter storm systems that feed the region. Key findings: - Multiple datasets and a 2025 study find decreasing winter precipitation across the western and parts of the central Himalayas, according to researchers quoted in the report. - ERA-5 analysis cited by an Indian researcher indicates roughly a 25% drop in snowfall in the northwestern Himalayas in the past five years versus the 1980–2020 long-term average. - The International Centre for Integrated Mountain Development reported the 2024–2025 winter had nearly 24% below-normal snow persistence, and four of the past five winters in the Hindu Kush Himalaya saw below-normal persistence. - The Indian Meteorological Department recorded almost no precipitation across much of northern India in December and said many northwest areas could see about 86% below the long-period average precipitation for January–March. Summary: Reduced winter snow and lower snow persistence are reported across wide parts of the Himalayan region, with researchers noting effects on seasonal runoff, glacier stability and related natural hazards. Undetermined at this time.
