Florida Sun Protection for Families: A Beach Vacation Guide
The short version: in Florida, plan your family’s outdoor time around the hours of strongest UV (roughly 10 a.m. to 4 p.m.), cover up with clothing, a wide-brimmed hat and sunglasses, and use a broad-spectrum SPF 30 or higher sunscreen on whatever skin is left, reapplied at least every two hours. Do it every day of the year, not only in summer. Below you will find what to put on, when to put it on, what changes for babies and young children, and how to handle a sunburn if one slips through.
TL;DR
UV rays are strongest from 10 a.m. to 4 p.m. daylight saving time, and they reach you on cloudy and cool days too.
Choose broad-spectrum, water-resistant sunscreen with SPF 30 or higher, and use about 1 ounce (a shot glass) for an adult body.
Reapply every 2 hours, and right after swimming, sweating or toweling off.
Babies 6 months and younger need shade and clothing, not sunscreen.
Shade, a 3-inch-brim hat and UV-blocking sunglasses do as much work as the bottle.

Why the Florida sun deserves a plan
The CDC says that in the continental U.S. UV rays are strongest from 10 a.m. to 4 p.m. daylight saving time (9 a.m. to 3 p.m. standard time), and that they can reach you on cloudy and cool days. The same page notes that water, cement and sand reflect UV, which matters on a beach where all three are within a few steps of each other.
Latitude plays a part, too. The CDC Yellow Book explains that UVB is most intense at mid-day and closer to the equator, and that snow, water and sand can raise your exposure by reflecting it. A Tampa Bay meteorologist adds that Florida’s low latitude gives it more UV than the rest of the country, with about 60% of the day’s UV arriving between 10 a.m. and 2 p.m. and sand reflecting up to 25% of it. She also points out that air temperature does not change UV strength, so a breezy 72-degree afternoon can burn as quickly as a hot one.
There is no off-season
Many families visit in winter and spring, when the Gulf breeze feels mild and the sun feels gentle. Lee Health, the Southwest Florida health system, reports that UV levels stay high in winter during peak hours, and a Lee Health physician notes that UV rays are present all year in Southwest Florida and are strong in January. The practical takeaway is simple: pack sunscreen for a February week the same way you would for July.
Choosing sunscreen for the whole family
Start with three words on the label: broad-spectrum, water-resistant, SPF 30 or higher. The American Academy of Dermatology (AAD) recommends exactly that combination, and Nemours KidsHealth gives the same advice for children, noting that the AAD recommends SPF 30 or higher for all kids regardless of skin tone. Darker-skinned children can get painful sunburns too.
The CDC’s own floor is lower, SPF 15 or higher, but for a beach week in Florida most families will be happier with SPF 30 to 50 and a generous hand.
Is SPF 70 better than SPF 50?
Not by much. A 2025 practical guide for health professionals reports that SPF 15 blocks about 94% of UVB, SPF 30 about 97% and SPF 50 around 98%. The gains shrink as the number climbs. A dermatologist quoted in an AAD survey summary adds that no sunscreen blocks 100% of UVB.
So the number on the bottle matters less than how much you apply and how often you reapply. A thick layer of SPF 30 put on correctly beats a thin layer of SPF 70 every time.
Mineral or chemical sunscreen
For children, UF Health Jacksonville prefers mineral sunscreens with zinc oxide or titanium dioxide. They are less likely to irritate sensitive skin and they work the moment they go on, while chemical formulas need at least 15 minutes before sun exposure. Nemours also suggests mineral formulas for sensitive skin and advises skipping products with PABA, which can cause skin allergies.
If you want a closer look at how the two types differ, this mineral versus chemical sunscreen comparison walks through the ingredients and how each feels on the skin.
Lotion or spray
UF Health recommends lotions and creams over sprays for kids because of the inhalation risk. Mayo Clinic says a spray used correctly can work as well as lotion, but lotion is more reliable because you can see and feel where it goes. Its suggestion is to use lotion most of the time and keep the spray for hard-to-reach spots or quick top-ups. Whichever you pick, check the date: the CDC notes that sunscreen without an expiration date has a shelf life of no more than three years.
How much to apply, and when
Most sunburns are a technique problem. The AAD says people who burn usually did not reapply, used too little or used expired sunscreen. Here is the routine that avoids all three.
Put it on at the house, before shoes and bags. The AAD says skin takes about 15 minutes to absorb sunscreen, and that an adult needs at least 1 ounce, roughly a shot glass, to cover skin that clothing does not. Nemours offers a handy alternative for the whole body: the teaspoon rule of 9 teaspoons. Do not forget ears, the back of the neck, the tops of the feet, the part in the hair and the backs of the knees.
Then set a timer. The AAD says to reapply every two hours and immediately after swimming or sweating. UF Health is more specific for kids in the water: every 40 to 60 minutes after swimming, sweating or toweling off. No product is truly waterproof. Mayo Clinic is clear that water-resistant labels are the best you will find, and Nemours says that resistance lasts 40 to 80 minutes in the water.
Children who go straight from the lanai to the pool will not be protected if the sunscreen goes on at the water’s edge. UF Health notes that applying right before a jump in the pool is not as effective. Build the application into the morning routine instead, and top up during a snack break.
Babies and young children
The youngest travelers need a different approach. The CDC says sunscreen is not recommended for babies 6 months old or younger, and the FDA recommends keeping infants out of the midday sun and dressing them in protective clothing if they have to be outside. HealthyChildren.org, from the American Academy of Pediatrics, suggests finding shade under a tree, an umbrella or a stroller canopy, and notes that up to 80% of UV can pass through clouds.
For a child of 6 months or older, including a 7-year-old, sunscreen is fine. Mayo Clinic says children can use the same sunscreen as adults, with a broad-spectrum SPF of at least 30, and about 1 ounce to cover the body while avoiding the eyelids. Ask your pediatrician about any specific concern with a baby’s skin, a rash or a known allergy before you pack.
For kids who are old enough to help, let them apply their own sunscreen under your watch. Turning it into a habit before they leave for college is a gift that lasts well beyond one beach week.
Clothing, hats, sunglasses and shade
Sunscreen is one layer, not the whole plan. The AAD recommends shade, protective clothing, a wide-brimmed hat and UV-blocking sunglasses alongside sunscreen, and suggests choosing clothing with a UPF number on the label. It also offers a quick shadow test: if your shadow is shorter than you are, it is time to find shade.
For hats, the CDC Yellow Book recommends a brim of at least 3 inches all the way around, shading the face, neck and ears, and says a standard baseball cap does not do that. Sun-specific caps with ear and neck flaps in UPF fabric are an option for kids who will not keep a floppy hat on. If you are putting together a packing list, a vented wide-brim fishing sun hat is the kind of style that covers the neck and ears.
FloridaHealthFinder suggests loose-fitting, tightly woven long sleeves and pants for adults and children, and sunglasses that block UVA and UVB (UV400 or a 100% UV protection label) for anyone over age 1. A rash guard with long sleeves is the easiest answer for kids who spend hours in the shallows. It never needs reapplying.
Planning a beach day around the sun
The easiest way to cut exposure is to shift the schedule. Think of the day in three parts.
Early morning. Sunrise walks and shelling are the best of a Captiva day, and the light is gentle. Our beaches guide can help you pick where to start.
Midday. This is the window for lunch, a nap, a pool dip in the shade, board games on the screened lanai or a quiet hour indoors. Florida Department of Health guidance cited by FloridaHealthFinder advises avoiding the sun particularly between 10 a.m. and 2 p.m., and notes that early summer is when UV can do the most damage.
Late afternoon. Back to the water with fresh sunscreen on, then a walk to watch the sun go down. Our local guide to sunset spots lists favorites.
On the sand, bring an umbrella or a pop-up tent, but do not treat it as a force field. The Bay News 9 meteorologist notes that even under an umbrella, sand can reflect up to 25% of UV, so sunscreen and a hat stay on. Keep drinking water close by, too. Our family beach safety notes cover currents and water conditions for the same days.
A home with a lanai, a private pool and shaded outdoor space makes this rhythm natural. Kids can swim at 9 a.m. and again at 4 p.m., and the hottest hours are spent in comfort. If you are weighing the sand against the pool, see how to choose between a private pool and the beach, and for the features that help families most, read our beachfront home guide.
If someone gets sunburned
Even careful families have an off day. Mayo Clinic’s first-aid guidance for mild to moderate sunburn is to take a nonprescription pain reliever such as ibuprofen or acetaminophen as soon as possible, cool the skin with a clean towel dampened with cool tap water or a cool bath, apply aloe vera or calamine lotion, and drink extra water for a day. Leave blisters alone. A 1% hydrocortisone cream can be used three times a day for three days.
Know when it is more than a vacation story. Mayo Clinic advises getting medical care right away for a sunburn with a fever over 103 F (39.4 C) along with vomiting, confusion, dehydration, dizziness or faintness. See a doctor, too, for large blisters or any on the face, hands or genitals, worsening pain, headache, eye pain or vision changes, or signs of infection. For an infant with any sunburn, call your pediatrician.
Our perspective on sun-smart family stays
After more than 30 years on Captiva, we have watched thousands of families arrive pale and excited, and the ones who have the best week are rarely the ones who spent the most hours on the sand. They are the ones who found a rhythm: sunrise on the beach, a long lunch in the shade, and the pool or the water again when the light softens. That rhythm is much easier when the house helps. A screened lanai gives toddlers a place to nap in the breeze. A private pool means you can swim for twenty minutes without packing the whole beach bag. A beachfront or bayfront home puts shade, water and a cold drink steps away from each other, so reapplying sunscreen becomes a quick stop, not an expedition. Our team knows the 40+ homes in our collection, and we are glad to talk through which ones suit your family: where the afternoon shade falls, which have a pool, and how close the beach is for little legs. Because you book direct with us, there are 0% platform fees, and you can call a local person who knows the island. Josh

FAQ
Is the UV stronger in Florida?
Generally, yes. Florida’s low latitude means more UV than most of the country, and UVB is most intense closer to the equator. The Southwest Florida sun is also strong in January, so plan for sun protection year-round.
Is SPF 70 actually better than SPF 50?
Only slightly. SPF 50 blocks around 98% of UVB, and higher numbers add very little beyond that, according to a 2025 health professional guide. Applying enough sunscreen and reapplying on time matters more than the number.
Can a 7-year-old use sunscreen?
Yes. Mayo Clinic says sunscreen can and should be used safely for children 6 months and older, and that kids can use the same sunscreen as adults. Pick a broad-spectrum, water-resistant SPF 30 or higher, and many parents prefer a mineral formula for sensitive skin.
What is the best sunscreen for Florida sun?
The best one is broad-spectrum, water-resistant, SPF 30 or higher, and one your family will actually wear. The AAD’s guidance is to apply about 1 ounce before heading out and reapply every two hours. For kids, mineral lotions with zinc oxide or titanium dioxide are a gentle choice.
