Understanding the UV Index is crucial for residents of Nyah, Australia, where the climate can lead to varying levels of sun exposure. Knowledge of UV levels is essential not only for preventing sunburn but also for maintaining long-term skin health. In Nyah's semi-arid climate, typical UV exposure risks peak midday, making it especially important to stay informed about the UV Index throughout the day. With UV readings often reaching a moderate level, taking precautions can help protect your skin and ensure you enjoy the sun safely.
The UV Index throughout the day offers a clear insight into solar intensity, peaking at 3 between 11:00 AM and 1:00 PM, signaling moderate sun exposure. The day begins with 0 UV at 7:00 AM, gradually rising to 1 by 8:00 AM and maintaining a low level until 10:00 AM. As the sun climbs higher, the index reaches 2 by mid-morning and then stabilizes at 3 during the lunch hours, suggesting the need for sun protection. By mid-afternoon, numbers dip back to 2 and diminish further to 1 as the evening approaches. Finally, the UV Index returns to 0 after 6:00 PM, marking a transition into a safer time to enjoy the outdoors without risk of sunburn.
