What is the Density of Snow and How Can It Increase?
Discover how snow density varies and factors that contribute to its increase, including thawing cycles and pressure.

Snow can get quite dense, especially when it's been exposed to cycles of thawing and refreezing or when it's packed down by pressure. Freshly fallen snow typically has a low density of about 50-70 kg/m³. However, in extreme cases, compacted snow can reach densities of 500-600 kg/m³, approaching the density of ice. This dense snow can be difficult to shovel and may require special equipment to move.
FAQs & Answers
- What factors affect the density of snow? The density of snow is influenced by temperature changes, cycles of thawing and refreezing, and how much the snow is compacted.
- How do you measure the density of snow? Snow density can be measured using a snow core sampler or by calculating the mass of a known volume of snow.
- Is dense snow easier or harder to shovel? Dense snow is typically harder to shovel due to its weight and compaction, often requiring specialized equipment.
- What is the maximum density of packed snow? Compacted snow can reach densities of 500-600 kg/m³, which is close to the density of ice.
