Mammoth Lakes has a cool mountain climate. Its high elevation means air pressure is lower than at sea level. Pacific storms often bring low pressure, strong winds, heavy snow, and quick changes in weather. High pressure can bring clear skies, cold nights, and dry air.
The Sierra Nevada mountains shape the weather. They force moist air upward, which causes heavy snow on the western slopes near Mammoth Lakes. The mountains also block some moisture from moving east, so the area is much drier than places near the Pacific coast. Sunny days can feel mild, but temperatures often drop quickly after sunset.
Winters are long, cold, and snowy. Mammoth Lakes commonly gets deep snow from November through April, with the most snow in the higher mountains. Spring can bring both snow and warm sunny days. Summers are usually dry, with warm afternoons and cool nights. Fall is often clear and mild at first, followed by colder weather and early snowstorms.
