Hindu Kush Himalaya Sees 27% Drop in Snow Persistence in Winter 2025–26

The Hindu Kush Himalaya region recorded a 27% decline in snow persistence in winter 2025–26 — the fourth straight year of decline — raising drought risks and threatening water supplies for farming, hydropower and drinking.

The Hindu Kush Himalaya (HKH) region recorded a 27% decline in snow persistence during the winter season from November 2025 to March 2026. Snow persistence refers to how long snow stays on the ground after it falls. This is the fourth year in a row that the region has seen falling snow levels.

This trend is closely linked to climate change. Less snow means lower river flows in early summer, when melting snow normally feeds the rivers. Many people in the region depend on these rivers for farming, hydropower and drinking water.

When snow-fed flows fall, communities have to rely more on groundwater, and the risk of drought rises in several river basins. This makes water management harder and threatens food and energy security.

For exam aspirants, the Hindu Kush Himalaya is often called the “Third Pole” because of its large stores of ice and snow. Remember the figure of a 27% drop and the link to climate change.

Key Points to Remember

  • 27% drop in snow persistence in HKH region, winter 2025–26
  • Fourth consecutive year of declining snow levels
  • Linked to climate change
  • Lowers early-summer river flows; raises drought risk
  • HKH is known as the “Third Pole”
