Understanding the UV Index is crucial for the residents of Santa Teresa, Australia, where the sun shines brightly in a BWh climate. With UV levels peaking at 6 during midday hours, awareness of these levels is essential to prevent sunburn and maintain optimal skin health. As the region often experiences intense sunlight, knowing when to seek shade or apply sunscreen can significantly reduce the risk of harmful UV exposure. Stay informed and enjoy the sun safely!
The UV Index starts low in the early morning, with a maximum of 1 at 07:00 and 08:00, making it a safe time for outdoor activities. As the day progresses, the intensity rises sharply, peaking at 6 between 11:00 and 12:00—the perfect time to take precautions if heading outside. By 13:00, it dips slightly to 5, and a more noticeable decline occurs in the afternoon, falling to 2 by 15:00. As the sun sets, the UV Index drops off sharply, reaching 1 by 16:00, and finally 0 past 18:00. It’s clear that midday sun calls for some sun safety measures, but the later hours provide a much more forgiving environment for enjoying the outdoors!

Throughout the year, the UV Index reveals significant seasonal variations, indicating periods of high risk for UV exposure. The months of January through April consistently exhibit extreme UV levels, with an index of 17 to 15 and a rapid burn time of just 10 minutes. As spring approaches, May slightly decreases to a very high UV index of 8, allowing for 15 minutes of burn time. The summer months, June and July, moderate further to a high index of 6 to 7, with burn times extending to 25 minutes. However, as autumn arrives, September experiences a spike back to extreme levels at 12, followed by October and November returning to 16, maintaining a burn time of 10 minutes. Finally, December mirrors the previous month with an index of 16. Visitors and residents should take precautionary measures during these high-risk months—especially from January to April, September, and October—by wearing protective clothing, applying sunscreen, and limiting sun exposure during peak hours to safeguard against harmful UV radiation.
