Does Idaho Have a Lot of Humidity?
Short answer: Not really. Much of Idaho, including Boise and Eagle, has a semi‑arid climate with low summer humidity compared to many parts of the country.
What “low humidity” looks like here
In the Treasure Valley, summer afternoons are typically dry, which most people find more comfortable than muggy air. Regional climate studies note that during hot weather in Idaho, afternoon relative humidity is often below 25%, sometimes near 15%.

Local notes for Boise–Eagle
- Expect warm, dry summers and crisp, occasionally snowy winters.

Why this matters for homebuyers
Low humidity can change how homes feel and perform. You may prioritize shade trees and window coverings over dehumidifiers. Landscaping often leans drought‑tolerant, with irrigation systems common.
Moving to dry air from a humid region?
Plan on extra moisturizer and a good water bottle for your first few weeks. Your hikes will feel different—sunny and dry—so start earlier and bring water.
