You’ll often see the fact that Mammoth Mountain averages 300 days of sunshine every year, but have you wondered how a place can have months of sunshine and incredible amounts of snow at the same time?

The answer is that when it snows in Mammoth Lakes, it means business. Not every storm will complicate travel plans, but you can bet on a few throughout the winter season that will close down roads and even Mammoth Mountain. You should always travel with chains in your car that you are comfortable installing when driving to Mammoth Lakes in the winter along with a shovel, extra blankets, food, and water in case you get stuck in the snow while on the road.

Serious storms can also close down Mammoth Mountain and other ski resorts in the area due to wind and avalanche danger, so if you’ll be in town during a serious storm have a backup plan in case you get snowed in.
