Facials for Boise's Dry Climate: Winter vs. Summer Skin Needs
Boise's climate doesn't just make winter cold and summer hot — it swings skin between two very different sets of needs each year. Here's what actually changes, and why the same routine rarely works for both seasons.
Request ServiceWhy Boise is a tougher climate for skin
Boise sits at roughly 2,700 feet in a cold semi-arid, high-desert climate where average humidity swings from around 75–80 percent in January down to roughly 30–36 percent by July. Elevation adds stronger UV exposure than the temperature alone suggests, and day-to-night temperature swings can exceed 30 degrees, which stresses skin's barrier in both directions.
What that means for skin
- Low humidity weakens the skin barrier and speeds up water loss through the skin (transepidermal water loss), especially indoors with heating or AC running
- Moisturizer that worked in a more humid climate often isn't enough here
- Sun exposure at elevation is stronger than it feels, in both winter and summer
- Skin can feel fine in the morning and tight or irritated by afternoon, particularly in winter
Two very different seasons
Winter vs. summer skin needs
Winter: barrier repair and richer hydration
Indoor heating plus cold, dry outdoor air is the toughest stretch of the year for most skin. Richer moisturizers with barrier-supporting ingredients like ceramides, along with a humidifier in bedrooms, help counter the moisture loss that both indoor and outdoor air cause.
Summer: lighter hydration and daily SPF
Strong high-desert sun and dust make daily SPF and gentler exfoliation more important, while the heavier products that worked in January can start to feel greasy or clog pores. Lighter, still-hydrating formulas usually work better through the hot, dry summer months.
Spring and fall: transition seasons
As humidity shifts in spring, skin can react with unexpected sensitivity or breakouts. Fall often means skin is recovering from a summer of sun and heat right as drier air returns, which makes early fall a practical time to focus on hydration and repair before winter sets in.

Questions
Climate & skin questions
Is Boise's air actually drier than average, or does it just feel that way?
It's genuinely drier than a lot of places people move here from. Average humidity swings from around 75 to 80 percent in January down to roughly 30 to 36 percent in July, and the high-desert elevation and intense sun add to how quickly skin loses moisture, especially indoors with heating or air conditioning running.
Should winter and summer skincare routines really be different, or is that overkill?
For most people in Boise, yes, it's worth adjusting. Winter calls for richer, barrier-supporting products because indoor heat and cold outdoor air both strip moisture, while summer usually calls for lighter hydration, daily SPF, and more attention to sun exposure, which is stronger at elevation than it feels.
