Florida has some of the highest sustained UV in the country. Its low latitude and year-round sun mean UV stays high even in winter, and reaches extreme levels in summer — sun protection matters every month here.

The World Health Organization recommends sun protection whenever the UV index reaches 3 or higher: apply broad-spectrum SPF 30 at UV 3–5, SPF 50 at UV 6–7, and SPF 50+ with reapplication every two hours at UV 8 and above.
