Yosemite typically enjoys a warm, dry summer, a mild, pleasant spring and fall, and a cool winter.
Higher elevations receive lots of snow, but the valley tends to get far less.
Whatever the season, be prepared by dressing in layers. Areas at higher elevations, such as Tuolumne Meadows, tend to be cooler than Yosemite Valley and other lower-elevation areas. So, when you're out in the park, carry a jacket or sweater. Park Newspaper Yosemite Guide, the park newspaper, offers current seasonal information on visitor services, wildlife, weather, safety, and complete schedules of park programs, including guided hikes, ranger talks, kids' programs, and special events. It is available free at park entrance stations and visitor centers.
