What’s the Weather Like in Idaho? A Season-by-Season Breakdown

If you’re considering moving to Idaho—or just visiting—you might be wondering: how’s the weather? The good news is, Idaho offers all four seasons with a wide variety of climates depending on where you land. Whether you’re relocating to Boise, Eagle, or anywhere across the Treasure Valley, knowing what to expect weather-wise can help you plan your move with peace of mind.

Spring:
March through May brings a beautiful transition. Temperatures range from the high 40s to mid-70s, and wildflowers start to bloom across the foothills. It’s a great time to explore the outdoors before the summer heat arrives.

Summer:
Idaho summers are warm and dry—especially in southern areas like Boise and Meridian. Expect highs in the 80s and 90s, with low humidity. Perfect for hiking, floating the Boise River, or spending the day on Lucky Peak Lake.

Fall:
September through November brings crisp air and golden leaves. Highs range from the 70s down to the 40s by late fall. It’s a short but stunning season that locals look forward to every year.

Winter:
Snow lovers, rejoice! While Boise gets light snowfall (about 18 inches annually), nearby mountain towns like McCall and Sun Valley offer full-on winter wonderlands. The Treasure Valley stays relatively mild, with average highs in the 30s and 40s.

In short, Idaho gives you variety without extreme weather headaches. You get seasons without hurricanes, tornadoes, or oppressive humidity. It’s one of the many reasons people are flocking to the Gem State.
