Is the Sun More Intense at Higher Elevations?

There’s nothing quite like that feeling at the top of a mountain. But here’s something adventure seekers often forget while chasing that summit: The higher you climb, the stronger the sun gets.

Even when it’s cold, cloudy, or windy, UV rays at higher elevations can be significantly more intense than they are at sea level. And because the air feels cooler, it’s easy to underestimate just how much sun exposure you’re getting.

Whether you’re hitting the slopes, hiking new heights, or exploring your favorite high-elevation city, wearing SPF isn’t optional — it’s essential. Ahead, we’ll explain why the sun’s rays are stronger up high, and which Supergoop! essentials will keep you hydrated, protected, and ready for every breathtaking view.

Why the Sun Is More Intense at Higher Elevations

According to the Skin Cancer Foundation, UV radiation exposure increases 4 to 5 percent with every 1,000 feet above sea level. That means at 10,000 feet, your skin is being hit with roughly 40 to 50 percent more UV radiation than it would be on the beach.

The atmosphere thins out at higher altitudes, which means there’s less air to absorb and filter harmful UV rays before they reach your skin. So, even if the temperature is cooler or the sun feels less direct, the UV index can still be much higher than it is at sea level.

In mountainous regions or high-altitude cities, that difference is especially noticeable, and it’s easy to forget that winter conditions can actually amplify your exposure. When UV rays reflect off ice and snow, they bounce back toward your skin.

The bottom line: Like anywhere, if you’re at high elevation, you need broad spectrum SPF 30 (or higher) and regular reapplication at least every two hours. The temps might be low, but the UV index can still be high.

4 Tips to Protect Your Skin from the Sun at High Altitudes

When you’re above the clouds, your SPF routine matters more than ever. Here’s how to keep your skin protected and comfortable while you climb, ski, or simply enjoy that mountaintop view.

1. Start Your Day with an SPF Moisturizer

Before you step outside, prep your skin with a hydrating SPF moisturizer. If your skin leans dry, Superscreen Hydrating Daily Cream SPF 40 delivers intense hydration in a soft, easily absorbing formula. And with expert SPF 40 protection, Superscreen makes it easy to put sun protection in your daily routine. If you prefer something lighter, Triple Prep Weightless Multitasking Moisturizer SPF 40 offers daily hydration in a soft, weightless texture ideal for normal to oily skin. It combines ectoin, hyaluronic acid, and glycerin to support your moisture barrier while defending against blue light, pollution, and radiation. Both options make SPF a seamless part of your morning skincare routine.

2. Apply Face Sunscreen
