Winter travel often means escaping to warmer, sunnier places—a welcome break from cold weather. But for babies, this sudden jump in UV exposure can be surprising and sometimes overwhelming.

According to the American Academy of Pediatrics (AAP) and the Canadian Paediatric Society (CPS), babies need careful sun protection year-round, especially when traveling to destinations where UV levels are significantly higher than at home.

Here’s what parents should know before packing up and heading toward the sun.

1. UV Levels Are Much Stronger Than You Might Expect

If you’re traveling from a northern or cloudy region, your baby’s skin is used to low winter UV. Suddenly being exposed to tropical or desert sunlight can be a big jump in intensity.

What feels mild to an adult can be too much for a baby’s thinner, more sensitive skin.

This is especially true for babies under 6 months, who should avoid sunscreen entirely. Learn more in Why Babies Under 6 Months Should Avoid Sunscreen.

2. Shade Becomes Your Best Friend

Whether you’re at a resort, walking along a beach, or sitting by a pool, consistent shade is one of the safest ways to protect your baby.

Useful tools include:

• Stroller sunshades

• Portable umbrellas

• Beach tents

• Breezy canopies

And remember: shade moves. Re-check every 15–20 minutes to make sure your baby is still protected.

3. Keep Outings Short During Peak UV Hours

Between 10 a.m. and 4 p.m., UV radiation is strongest—especially in sunny destinations.

For babies under 12 months, the safest approach is:

• Enjoy early morning and late afternoon time outdoors

• Keep midday outings short and shaded

• Choose routes with shade when walking

This keeps your baby comfortable and reduces sun exposure during the hottest part of the day.

4. Lightweight UPF Clothing Makes Travel Easier

In warm destinations, babies won’t be bundled as they are in cold climates. This is where lightweight UPF layers really shine:

• They cover delicate skin without overheating

• They block UVA and UVB

• They don’t wash off like sunscreen

• They’re easy to travel with

• They’re recommended for babies under 6 months who can’t wear sunscreen

5. Don’t Forget About Indirect Sun Exposure

Even with shade, UV can still reach your baby through:

• Reflections from sand

• Water

• Pool decks

• Light-colored surfaces

These reflections can cause unexpected exposure, especially for babies lounging or napping outdoors.

Small adjustments help:

• Rotate your baby’s position periodically

• Face their stroller away from bright surfaces

• Add a breathable sun cover when the surroundings are extra reflective

6. Be Extra Cautious Near Water

Water reflects UV efficiently, which increases exposure even under partial shade.

For babies:

• Avoid direct sun near water - there are tons of full coverage UPF 50 swimwear brands that have swimwear for babies & toddlers. We highly recommend having some on hand

• Keep shaded when possible

• Never rely on water-resistant sunscreen before 6 months

• Prioritize soft coverings + hats instead

If your baby is over 6 months and using mineral sunscreen, reapply often—especially after splashing or sweating.

7. Protect During Travel Days, Too (Airplanes + Cars)

Many parents are surprised to learn:

✦ Airplane windows let in UVA

✦ Car windows block UVB but not UVA

So your baby may receive sun exposure during:

• Taxiing

• Sitting on the sunny side of the plane

• Long car rides at your destination

Simple solutions:

• Use a soft breathable blanket or muslin draped away from their face

• Choose the shaded side of the aircraft when possible

• Use car window shades or reposition their seat if sunlight hits directly

8. After 6 Months: Sunscreen Helps - but Clothing Still Matters

Once your baby is older than 6 months, pediatric guidance allows for sunscreen use, but it should support - not replace - other protective measures.

Best practices:

• Choose mineral sunscreen (zinc oxide or titanium dioxide)

• Apply to exposed areas only

• Reapply every 2 hours and after water play

• Combine with lightweight UPF layers and hats

This balanced approach keeps your baby protected and comfortable.

Final Thoughts

Winter travel with your baby can be filled with sunshine, warmth, and wonderful memories. With thoughtful sun protection habits - especially in new climates - you can enjoy your getaway with confidence, knowing your baby’s delicate skin is safe.
