Australia doesn't mess around with UV. The Cancer Council of Australia puts it plainly - two in three Australians will be diagnosed with skin cancer by age 70. That's not a stat you read and forget when you're packing your daughter's beach bag.
So when you're deciding what she wears on the sand, how much skin actually gets covered is a real question. Are long sleeve surfsuits genuinely better for sun protection than a bikini? Yes. But it's not as black and white as it sounds - and your teen doesn't have to look like she's dressed for a wetsuit competition to stay safe.
How Much Does a Long Sleeve Surfsuit Actually Protect?
Most quality surfsuits use fabric rated UPF 50+, which blocks over 98% of UV radiation. A regular girls swimwear bikini? The exposed skin gets nothing, and even the fabric itself often sits somewhere between UPF 15 and 25.
What Does UPF Mean?
UPF stands for Ultraviolet Protection Factor. Think of it like SPF in sunscreen, but for fabric. A UPF 50+ rating means the material only lets through 1/50th of UV rays. For a kid who's in and out of the water for four hours straight, that gap matters - and it matters just as much on an overcast day, when UV levels stay high even when the sun doesn't feel strong.
A long sleeve surfsuit covering the torso, arms and sometimes legs simply means less skin copping direct UV. That's the straightforward case for them.
Does That Mean Bikinis Are Off the Table?
No. Not even close.
Sun protection is about covering skin smartly, not covering every bit of it. A good teen bikini worn with a rashie, some zinc and a hat still gets the job done. Teens who want to move freely in the surf, train for nippers, or just hang out on the beach without feeling overdressed - a bikini with the right layers works fine.
The point is to layer up thoughtfully, not to treat it as a surfsuit or nothing.
What Should You Look for in Beach Swimwear for Girls?
Whether you're going with a surfsuit or the bikini-plus-rashie combo, here's what actually matters:
- UPF rating on the fabric - Look for UPF 50+, not just "sun protective"
- Fit and coverage - A surfsuit that rides up constantly defeats the purpose
- Durability in saltwater and chlorine - Cheap fabrics fade fast and drop their UPF rating over time
- Style your teen will actually wear - Sun protection only works if it goes on
That last one isn't a throwaway point. A rashie left in the bag because it "looks daggy" is doing absolutely nothing.
How Does Salty Ink Designs Approach This?
Salty Ink Designs is an Australian swimwear brand that actually gets the brief. Their pieces are built for real Australian beach days - where style and practicality don't have to fight each other.
Two options worth looking at for girls and teens:
- The Miss Stardust Bikini - a fun, current bikini that works as a base layer under a rashie or on its own for lower UV days. It's the kind of thing teens will reach for, which is half the battle.
- The Beach Boho Tube Bikini - a boho-styled piece that pairs well with a long sleeve rashie or a light coverup. For teens after a relaxed beach look without going full surfsuit, this one works.
Neither is a long sleeve surfsuit - but both are made with Australian conditions in mind and sit well within a sensible sun-safe routine.
Frequently Asked Questions
Is a surf suit enough on its own, or do you still need sunscreen?
A surfsuit takes care of most of the body, but your face, neck, hands and feet are still out there. Sunscreen on uncovered skin is still a must - reapply every two hours, and more often if the kids are in and out of the water all day.
At what age should girls start wearing surfsuits for sun protection?
Earlier is better, full stop - but it matters most for younger kids whose skin is more sensitive to UV damage. For teens, it often comes down to what they'll actually wear. A surfsuit is great if they're into it. If they're not, a rashie and quality girls swimwear Australia works just as well when it's worn properly.
How do I know if a fabric is actually UPF rated?
Check for a label that spells out the UPF number - not just words like "sun safe" or "beach wear." A proper UPF 50+ rating will be on the tag or in the product description. If it's not there, assume it isn't rated.
Does colour affect UV protection in swimwear?
Somewhat. Darker and brighter colours - deep blue, red, black - absorb more UV than lighter shades. But fabric rating counts for far more than colour. A pale UPF 50+ fabric beats a dark unrated one every time.
The Bottom Line
Long sleeve surfsuits do give better technical sun protection than a bikini. That part's simple. But a safe beach day is about more than the swimwear - it's sunscreen on exposed skin, a hat, and staying out of the sun during peak hours (10am to 2pm across most of Australia).
The swimwear that actually protects your teen is the one she'll wear. Have a look at what Salty Ink Designs has going - they make girls swimwear that holds up on real Australian beach days without feeling like a tradeoff.
