Mount Rainier in May
Good time to visit
May represents the park's emergence from winter hibernation. While high-elevation trails remain snow-covered, the reopening of Paradise Road signals the start of the real visiting season.
Weather
May finally brings consistent spring weather to the lower elevations, with mild days and cool nights. Rain showers are frequent but brief. Snow still blankets everything above 4,000 feet, keeping most high-country trails closed.

All Months
Summer is king at Mount Rainier, but the season is shorter than you think. Snow can linger at Paradise until July, and wildflower peak typically hits mid-July through August - though climate change has been shifting these windows earlier. September offers the sweet spot: warm days, cool nights, fewer crowds, and reliable trail access. But here's the reality check: weather is unpredictable year-round. I've seen snow in August and 70-degree days in October. Winter transforms the park into a cross-country skiing wonderland, though only the road to Paradise stays open. Spring means mud season and limited trail access, but also fewer people and dramatic waterfalls from snowmelt. Check trail conditions obsessively before visiting - the park service updates their website daily during peak season. Pro tip: if you can only visit once, aim for the last week of July when wildflowers are peaking and most high-elevation trails are accessible.
