Florida’s sun is not a season. It is a year-round exposure that drives most of the skin cancers we diagnose at our Windermere office, including basal cell carcinoma, squamous cell carcinoma, and melanoma. The single most useful daily habit for lowering that risk costs nothing: check the UV index before you head outside.
The UV index is a 0 to 11+ scale published by the National Weather Service for your zip code. It estimates how quickly unprotected skin will burn at ground level. In Central Florida, summer readings sit at 10 or 11 (very high to extreme) through most of June, July, and August, and they are typically moderate (4 to 6) in cooler months, rising only on clear midday days. Knowing the number changes what reasonable sun protection looks like that day.
What the number means for your day
Use the UV index to set three decisions: when to be outside, what to wear, and how often to reapply sunscreen.
When. At UV 8 and above, unprotected fair skin can burn in 15 minutes or less. Schedule yard work, runs, golf, and pool time before 10 a.m. or after 4 p.m., when the index drops. The hours from 10 to 4 are when most cumulative damage happens.
What to wear. A wide-brim hat, UPF-rated long sleeves, and UV-blocking sunglasses do more than any sunscreen on a UV 10 day. Cover what you can, then apply broad-spectrum SPF 30 or higher to everything that remains exposed: face, ears, neck, hands, and the tops of the feet.
Reapplication. At UV 7 or above, reapply sunscreen every two hours, and immediately after swimming, towel drying, or heavy sweating. Most patients use roughly half the amount needed. A shot-glass volume covers an average adult body.
Built-in tools that help
You do not need a separate app. The iPhone weather app and most Android weather apps display the UV index on the main screen. The free SunSmart Global UV app from the World Health Organization sends a daily peak-index alert. Some smartwatches surface it as a watch-face complication. Pick one and let it become part of your morning glance, like checking the temperature.
When to bring it to a dermatologist
UV discipline lowers risk, but it does not catch what is already there. We recommend an annual full-body skin exam for every adult, and sooner if you notice a new spot, a changing mole, a sore that will not heal, or a lesion that bleeds or itches. Florida residents, fair-skinned patients, and anyone with a personal or family history of skin cancer benefit from a documented baseline.
If it has been more than a year, or if something on your skin has been on your mind, call our Windermere office or request a skin check online. A short visit is the fastest way to turn daily sun habits into long-term protection.
