Do You Really Need Sun Protection in Winter?
The Aussie UV Myth That Catches Most Parents Out
Think sun protection is a summer only job? In many parts of Australia, UV stays high enough to damage little skin right through winter. Here is what every parent needs to know, from a mum and melanoma survivor.

It is a grey, chilly Tuesday in the Shire. You are bundling the kids into jumpers, the heater is on in the car, and the last thing on your mind is a hat and sunnies. I get it. For years, I thought exactly the same way. Cold day, no sun, no worries.
Then I was diagnosed with melanoma in my early thirties, and I learned the hard way that the sun does not work the way we assume it does.
If there is one thing I wish every Aussie parent knew, it is this. The temperature you feel has almost nothing to do with the damage the sun can do. So let me walk you through it, mum to mum, without the scary stuff and without the lecture.
The myth that catches almost all of us out
Most of us grew up believing sunburn is a summer problem. Beach days, cricket, the park, the pool. Cool weather feels safe, so we pack the hats away in June and forget about them until the warm months roll back around.
Here is the catch. What actually damages skin is UV radiation, and UV is completely invisible. You cannot see it and you cannot feel it. It has nothing to do with how warm or bright the day feels. As the Cancer Council puts it, UV can be high even on cool and overcast days, which is exactly why we cannot rely on a chilly morning to tell us we are safe.
So the honest answer to "can my kids get sun damage in winter?" is yes, in plenty of parts of the country, they absolutely can.
The one number that actually matters
Forget the thermometer. The number to watch is the UV Index.
It runs from 0 to 11 and above, and the guidance across Australia is simple. Whenever the UV Index hits 3 or above, sun protection is recommended. That is the point where UV starts to damage unprotected skin. In fact, when levels are 3 or higher, just fifteen minutes of unprotected exposure is enough to begin causing harm.
Here is where winter gets interesting.
It depends on where you live
In the northern half of Australia, UV levels sit at 3 or above all year round. There is no winter off season up there at all.
In the southern parts of the country, including here in Sydney, UV does dip lower through the coldest months, and in some places it drops below 3 in June and July. When that happens, the Cancer Council actually says a little time outdoors with some skin uncovered is fine and even helpful for vitamin D. I love that this is not about fear or covering up every second of the day. It is about knowing your number.
The trouble is, most of us are guessing. The easiest fix is to check the free SunSmart app or the Bureau of Meteorology website before you head out. It takes five seconds and it tells you exactly what today calls for.
The winter moments we forget
Even in the cooler months, there are a few everyday situations where UV sneaks up on families.
In the car. UVA rays, the kind that cause long term skin damage, pass straight through glass. That means little ones can pick up exposure through the car or classroom window on a cold day without anyone feeling a thing.
On cloudy days. Thick cloud filters some UV, but thin cloud lets plenty through. A dull sky is not the all clear it feels like.
On the snow. If your family heads to the alpine for a winter escape, take extra care. UV is stronger at altitude, and snow is highly reflective, so it effectively doubles up the exposure. Same goes for a winter beach walk near the water.
At weekend sport and school pickup. Those long stretches standing on the sideline or waiting at the school gate add up, especially in the northern states where the UV Index rarely drops.
Simple sun safe habits for the cooler months
You do not need to overhaul your whole routine. A few easy anchors do the job.
- Check the UV, not the temperature. Make the SunSmart app part of your morning, like checking the weather.
- Keep the hats in rotation. A UPF50+ broad brimmed or bucket hat protects the face, neck and ears, the spots that cop the most sun. Ours are made to be comfy enough that kids actually keep them on.
- Slide on the sunnies. UV400 polarised sunglasses protect little eyes from glare year round, and winter glare off wet roads and water can be surprisingly harsh.
- Do not skip the exposed bits. On a UV 3 or above day, a bit of sunscreen on faces and hands still matters, even in July.
- Remember the babies. Infants and toddlers have thinner, more sensitive skin, so shade, clothing and a good hat are the gentlest way to keep them protected whatever the season.
A gentle word from me
I did not build Ombra & Sole to sell you more stuff or to make you feel guilty on a cold Tuesday. I built it because I sat in a hospital bed as a young mum, terrified, wishing I had understood any of this sooner.
Sun safety is not a summer habit. It is a year round one, and the beautiful part is that it becomes second nature once it is built into the everyday. A hat by the door. Sunnies in the nappy bag. A quick glance at the UV before the school run. Small things, done often, that quietly protect the little people you love most.
While you are here, this is also your friendly reminder to book your own skin check if it has been a while. I promise it is worth the ten minutes.
Stay warm, and stay sun safe.
