Mount Rainier in June: what the park service says
June at Mount Rainier usually brings daytime temperatures in the mid-50s°F at Paradise and the mid-60s at Longmire, and the park warns that summer can still be wet and cool. Snow stays at 5,000 to 8,000 feet into mid-July, so higher trails may still be snowbound. The Ohanapecosh Visitor Center generally opens in late June, but check its status first: it stayed closed through 2026 for a campground construction project.
