July Is UV Safety Awareness Month: The Mid-Summer Check-In
Peak UV, peak vigilance — here's your refresher.
The UV Index runs from 1-2 (low) to 11+ (extreme), and the EPA advises sun protection any time it reads 3 or higher — which in much of the U.S. is most of the day in July.
Dermatologists frame midsummer as the time to tighten habits, not relax them: with the sun highest and days longest, daily reapplication and shade during peak hours matter most.
Questions we get a lot
What does the UV Index tell me?
The UV Index is a 1-to-11+ scale of how intense the sun's UV is at a given place and time. The EPA recommends sun protection whenever it reaches 3 or higher; in July across most of the U.S. it routinely hits the high (8-10) or extreme (11+) range around midday, when shade, clothing and reapplied sunscreen matter most.
How often should I reapply sunscreen in summer?
Reapply broad-spectrum SPF 30+ about every two hours of sun exposure, and immediately after swimming, heavy sweating or toweling off. A single morning application wears down through a long summer day, so a reapplication routine is the core of any midsummer sun-safety plan.
Is sunscreen necessary on cloudy summer days?
Yes. Up to 80% of UV rays pass through clouds, and UVA — the deeper-penetrating, aging wavelength — stays fairly constant regardless of cloud cover. A cooler, overcast July day can still deliver enough UV to burn, so daily broad-spectrum sunscreen is recommended.
