Sun Care
Reef-Safe Sunscreen: What the Label Legally Has to Say

Table of contents
Why this matters
A beach day goes wrong in small ways: sunscreen left in a hot car, an umbrella that folds at noon, a cooler that turns to water by 1pm. Which filters are banned in Hawaii, Australia and Mexico — and the formulas that never leave a white cast.
We built this guide from three seasons of trips across Florida's Gulf coast, New South Wales and the Greek islands — with the same core kit each time so we could compare results honestly.
The gear we recommend
Two products carried the most weight in testing. Both are widely available and both survived a full salt-water season without rust or fading.
Editor's ChoiceBeach Bags
Oversized Woven Straw Beach Tote
Holds two towels, a 32oz bottle and sunscreen without losing its shape. Sand shakes straight out of the open weave.
Best ValueBeach Towels
Sand-Free Quick-Dry Turkish Towel
Dries in under 20 minutes, folds down smaller than a paperback and never drags sand into the car.
How we tested
Every cooler ran a 48-hour ice-melt test in 90°F sun with a fixed ice-to-air ratio. Umbrellas were staked in loose sand and measured against 25 mph gusts. Towels were weighed wet, then again after 20 minutes of shade drying.
FAQs
How often should sunscreen be reapplied at the beach?
Every two hours, and immediately after swimming or towel-drying — even with water-resistant formulas, which are only rated for 80 minutes in water.
What size cooler fits a family of four for a full day?
A 25–35 quart cooler holds lunch, snacks and around 12 drinks with ice. Anything larger becomes hard to carry across soft sand without wheels.
How do I stop sand getting into everything?
Pack a small bottle of baby powder to brush sand off damp skin, keep a wet-dry bag for swimsuits, and choose flat-weave towels instead of terry.

The baby powder trick genuinely changed our beach days with two toddlers. Wish I'd known years ago.

Bought the vented umbrella after reading this. First windy day at Bondi and it didn't budge.
