Picture this: It's a cloudy day, and you plan a fun outdoor adventure. The sky is overcast, and you think you're safe from the sun's harmful rays. But can you let your guard down?
In this blog post, we'll explore the question, "Can you get a sunburn on a cloudy day?" We'll explore the risks, protective measures, and other important considerations to help you stay sun-safe, even when the clouds roll in.
Can the Sun's Rays Penetrate Through Clouds?
Clouds may seem like a shield against the sun, but the truth is that some of the sun's rays can still reach your skin, even on a cloudy day. While clouds can block or scatter some of the ultraviolet (UV) radiation, not all clouds are equally effective. The level of protection offered by clouds depends on their thickness, density, and composition.
So, what are the risks of getting sunburned on cloudy days? It's important to remember that UV rays can still penetrate through clouds, especially thin or scattered ones.
The intensity of UV radiation can vary depending on several factors, such as the time of day, altitude, and geographic location. Even on a cloudy day, you can still be exposed to significant UV radiation, increasing the potential risk of sunburn and long-term skin damage.
Do all types of clouds allow UV rays to pass through?
Not all clouds are created equal when it comes to UV protection. Some clouds, like thick cumulus clouds or dark storm clouds, can provide greater shielding from UV rays. Regardless, thinner clouds, such as cirrus clouds, may allow more UV radiation to pass through. Be cautious and protect your skin regardless of cloud type, as even thin clouds can expose you to harmful UV rays.
The role of UV index in sunburn
The UV Index is a measurement that indicates the strength of UV radiation from the sun. It's an essential tool for assessing the risk of sunburn and taking appropriate precautions. The higher the UV Index, the greater the risk of sunburn. Even on cloudy days, UV radiation can reach moderate to high levels, especially in locations with reflective surfaces like sand, water, or snow. Checking the UV Index before heading outdoors can help you plan and protect your skin accordingly.
Factors Influencing the Intensity of UV Rays
Several factors can influence the intensity of UV rays. Here are a few things to keep in mind:
1. Time of day and angle of the sun: UV radiation is strongest between 10 a.m. and 4 p.m. when the sun is at its highest point in the sky. During these hours, it's crucial to take extra precautions to avoid sunburn.
2. Altitude and geographic location: UV intensity increases with altitude and gets closer to the equator. Be especially vigilant about sun protection if you're at a higher elevation or near the equator.
3. Reflection from surfaces: UV rays can reflect off surfaces like water, sand, snow, or concrete, leading to increased exposure. Remember to protect your skin even in shaded areas near reflective surfaces.
Can You Get Sunburned Through Your Clothing?
The honest answer? It depends. Thin, lightweight fabrics like plain cotton or loosely woven materials may allow UV rays to penetrate your clothes, increasing the risk of sunburn. Wet clothing can also become less effective at blocking UV rays, which means more caution should be taken during water-based activities.
On the flip side, darker colors absorb more UV radiation than lighter shades, which may increase the protection they provide. Then, there’s UPF-rated apparel, which is specifically designed to block out a majority of the sun’s rays from reaching the skin.
UPF apparel, like men’s and women’s sun protective clothing from Free Fly, is designed for life outdoors, so you never have to sacrifice comfort and breathability or worry about getting sunburned through your clothes.
Recognizing the symptoms of a sunburn
Whether it's a sunny or cloudy day, it's important to recognize the symptoms of sunburn. Signs of sunburn typically appear a few hours after sun exposure and may include redness, pain, swelling, and, in severe cases, blisters. If you experience these symptoms, taking immediate action is necessary to soothe your skin and prevent further damage.

How To Protect Yourself from Sunburn on Cloudy Days
Now that you know the risks, let's talk about how to protect yourself from sunburn on cloudy days and sunny days alike. Here are some simple yet effective measures you can take:
1. Seek shade: When possible, stay in the shade, especially during peak sun hours when UV radiation is the strongest.
3. Apply (and reapply) sunscreen: Even on cloudy days, applying a broad-spectrum sunscreen with SPF 30 or higher to any exposed skin is crucial. Remember to reapply frequently every two hours or more if you're sweating or swimming.
4. Wear a wide-brimmed hat and sunglasses: Investing in a wide-brimmed hat is not just a style statement; it's a practical way to shield your face and neck from direct UV radiation. The wider the brim, the better the coverage. Couple your hat with a pair of 100% UV-blocking sunglasses to protect your eyes.
5. Stay hydrated and moisturize your skin: A well-hydrated body is better equipped to deal with sun exposure. Drinking plenty of water not only helps to maintain your body's natural cooling system but also aids in keeping your skin healthy and resilient. Along with hydration, it's essential to keep your skin moisturized. Regular application of a good quality moisturizer helps to maintain the skin's protective barrier, improving its natural defense against harmful UV rays. Opt for a moisturizer with built-in SPF protection for an additional layer of defense. Not sure how much to use? Check out our guide on SPF 30 vs. 50.
