Why You Still Need Sunscreen on Cloudy Days (and Which One to Use)
If you’re heading out in Naples on a gray, overcast morning, sunscreen might be the last thing on your mind. But here’s a surprising fact: up to 80% of the sun’s UV rays can pass through clouds.
That means your skin is still at risk - especially in sun-drenched areas like Park Shore, where time outdoors is part of daily life, whether you’re walking the dog, boating, or grabbing lunch on 5th Ave.
At Naples Dermatology, we educate our patients on how to protect their skin year-round - even when the sun isn’t shining.
Why Cloudy Days Still Require Sunscreen
Cloud cover blocks visible light, but it doesn’t stop ultraviolet radiation, which is the real culprit behind sunburns, skin aging, and skin cancer.
There are two types of UV radiation to know:
UVA: Penetrates deeply, causes premature aging, and is constant all day—even on cloudy days.
UVB: Responsible for sunburns and can fluctuate depending on time of day and season.
Both types can contribute to skin cancer. And both get through clouds.
Naples UV Index = High Risk
In Florida, even “mild” days can carry a UV index of 6 or higher, which is considered moderate to high risk. Monitor the day’s risk here. Reflective surfaces like water, sand, and concrete increase your exposure—so a walk along the Park Shore promenade could quietly damage unprotected skin.
What Kind of Sunscreen Should You Use?
Dermatologists generally recommend:
Broad-spectrum protection (blocks UVA & UVB)
SPF 30 or higher
Water-resistant formulas for active days
Mineral sunscreens with zinc oxide or titanium dioxide for sensitive skin
Our Dermatologist-Recommended Picks
Here are a few patient favorites available at local Park Shore stores or online:
EltaMD UV Clear - Lightweight, great for sensitive skin and rosacea
La Roche-Posay Anthelios - Broad-spectrum, non-greasy, blends well
Neutrogena Sheer Zinc - Affordable mineral option with SPF 50
Blue Lizard Sensitive - Reef-safe, mineral-based, good for families
Pro tip: Apply 15 minutes before going outside - and reapply every 2 hours, or after sweating or swimming.

What About Makeup With SPF?
It helps - but it’s not enough. Think of makeup with SPF as a backup layer. For full protection, use a dedicated facial sunscreen underneath.
Naples Lifestyle = Year-Round Skin Awareness
In a place like Naples, sun protection isn’t just for beach days. UV exposure adds up - on your commute, while walking your dog, or even sitting near windows at home or work.
We’ve seen many cases of sun damage in patients who rarely “sunbathe” but are regularly outdoors in the Florida climate.
