Summer Travel Sun Safety: Packing the Right SPF
Protection that survives a beach vacation abroad.
Reflective surfaces raise beach UV exposure: dry sand reflects about 15% of UV and water roughly 10-30%, on top of the direct overhead sun on a summer vacation.
Dermatologists advise travelers to pack a water-resistant broad-spectrum SPF 30+ and reapply every two hours, since a single morning application won't survive a full day of swimming and sweating abroad.
Questions we get a lot
Should I pack sunscreen or buy it at my destination?
Either can work. Packing a formula you trust avoids surprises, but check airline liquid limits and local reef rules — places like Hawaii ban the sale of oxybenzone and octinoxate sunscreens. Buying locally is convenient and may offer formats suited to the climate; just confirm it's broad-spectrum SPF 30+ and water-resistant.
How often should I reapply sunscreen on a beach vacation?
Reapply broad-spectrum sunscreen about every two hours, and right after swimming, heavy sweating or toweling off. Sand and water reflect extra UV onto your skin, so even under an umbrella a full beach day calls for generous reapplication plus a hat and UV-protective clothing.
When is the UV index high enough to need protection?
Dermatologists generally recommend sun protection whenever the UV Index is 3 or higher. Many summer beach destinations sit at very high UV most of the day, so a water-resistant broad-spectrum sunscreen, reapplied regularly, is essential while traveling.
