Winter often brings a sense of relief when it comes to sun safety. Cooler temperatures, cloud cover, and shorter days can make it feel like the risks of sun exposure are behind us. But when it comes to melanoma, that mindset can be dangerously misleading.
Ultraviolet (UV) radiation doesn’t disappear in winter. In fact, UV levels can still be high enough to cause skin damage, even on cold or overcast days. Because the sun’s warmth is less noticeable, many people underestimate their exposure and skip protective habits like sunscreen, hats, and seeking shade.
This is important because melanoma, the most serious form of skin cancer, is strongly linked to UV exposure over time. Damage accumulates gradually, and even incidental exposure during winter, like walking the dog, sitting by a window, or outdoor sports, can contribute to long-term risk.
Understanding your UV exposure is one of the most effective ways to stay protected year-round. Instead of guessing based on the weather, checking real-time UV levels gives you a clearer picture of when protection is needed. Even in winter, UV levels can reach moderate or high ranges, especially in Australia where UV radiation is among the highest in the world.
That’s where technology can make a real difference. The SunSmart Global UV app, developed by Cancer Council VIC, allows you to monitor UV levels in real time, helping you make informed decisions about your sun safety wherever you are. With easy-to-understand updates and alerts, you can know exactly when to apply protection and when your risk is lower.
Winter doesn’t mean zero risk—it just means the risks are less obvious. Staying aware of UV exposure throughout the year is a simple step that can have a lasting impact on your skin health.
