Climbing Season June and July are the best months for climbing Mt. Shasta. Some climbers prefer the early summer months so they can take advantage of smoother going over ice and snow. On the south side, rockfall danger increases during late summer and fall. Glacier routes are often safest in late summer and early fall when crevasses tend to be more visible and more easily avoided. Check the weather forecast for incoming storms or unsettled weather.
Avalanches can pose a hazard both in winter and spring.
