Located high in California’s Sierra Nevada Mountains, Mammoth is famous for receiving some of the deepest snowfall in North America. In an average winter, the area gets hundreds of inches of snow, making it a favorite destination for skiing, snowboarding, and other winter activities.
This guide explains how much snow Mammoth typically receives, how snowfall varies from year to year, what affects snow totals, and why the area is known for its incredible winter conditions.

How Many Feet of Snow Does Mammoth Get Each Year?
Snowfall changes every season depending on weather patterns.
| Winter Type | Snowfall |
|---|---|
| Low Snow Year | 15–25 feet |
| Average Year | 30–35 feet |
| Good Snow Year | 40–50 feet |
| Exceptional Year | 60–70+ feet |
Some record-breaking winters have brought well over 700 inches (nearly 60 feet) of snow.
Why Does Mammoth Get So Much Snow?
Several natural factors contribute to Mammoth’s heavy snowfall.
High Elevation
The mountain summit reaches over 11,000 feet, where temperatures remain cold enough for snow throughout much of winter.
Sierra Nevada Mountains
Moist air from the Pacific Ocean rises over the Sierra Nevada. As it climbs, it cools and releases large amounts of snow.
Winter Storms
Powerful Pacific storms, often called atmospheric rivers, can dump several feet of snow within just a few days.
Monthly Snowfall in Mammoth
Snowfall is not evenly distributed throughout the season.
| Month | Typical Snowfall |
|---|---|
| October | Light snow possible |
| November | 1–3 feet |
| December | 4–8 feet |
| January | 6–9 feet |
| February | 6–9 feet |
| March | 6–10 feet |
| April | 3–6 feet |
| May | Light snow possible |
January through March are usually the snowiest months.
Snowfall vs Snow Depth
Many people confuse these two measurements.
Snowfall
This measures the total amount of snow that falls during the season.
Example:
- 400 inches of snowfall equals about 33 feet of snow.
Snow Depth
Snow depth is how much snow is actually on the ground at one time.
For example:
- Seasonal snowfall: 33 feet
- Snow depth on the mountain: 8–15 feet
Snow naturally compacts over time, so the snow depth is much lower than the total snowfall.
Record Snowfall Seasons
Some winters have produced extraordinary snowfall.
| Season | Approximate Snowfall |
|---|---|
| Exceptional winters | 600–700+ inches |
| Historic seasons | Nearly 60 feet of snow |
Heavy snow years usually occur during strong Pacific storm cycles.
How Does Mammoth Compare With Other Ski Resorts?
| Ski Resort | Average Snowfall |
|---|---|
| Mammoth Mountain | About 33 feet |
| Lake Tahoe | 25–35 feet |
| Aspen | 25–27 feet |
| Park City | 30 feet |
| Alta, Utah | Around 45 feet |
Mammoth consistently ranks among the snowiest ski resorts in North America.
What Determines Snowfall Each Year?
Several weather patterns influence seasonal snowfall.
El Niño
Strong El Niño winters often bring increased precipitation to California.
La Niña
La Niña winters can produce either above-average or below-average snowfall depending on storm tracks.
Atmospheric Rivers
These moisture-rich storms are capable of producing multiple feet of snow in just a few days.
Why Heavy Snow Benefits Visitors
Large snowfall totals create excellent winter conditions.
Benefits include:
- Longer ski seasons

Visitors should always check weather forecasts before traveling.
