Understanding the UV Index is crucial for residents of Oromocto, Canada, where sun exposure can vary significantly throughout the day. Awareness of UV levels not only aids in preventing sunburn but also plays a vital role in maintaining long-term skin health. Given Oromocto's Dfb climate, which features warm summers and moderate UV radiation, it's essential to recognize the risks associated with high UV readings, particularly between 10 AM and 4 PM when levels peak at 9. Staying informed about the UV Index can empower you to enjoy the outdoors safely while safeguarding your skin against harmful effects.
Throughout the day, the UV Index fluctuates dramatically, peaking during the midday hours. Starting at a low of 1 at 07:00, the index rises steadily, reaching 3 by 09:00. As 10:00 approaches, it escalates to 5, but the real intensity hits between 12:00 and 14:00 when it peaks at 9. During this window, it's crucial to take sun safety precautions. As the afternoon progresses, the UV levels begin to taper off, dropping to 8 at 15:00 and gradually declining further to 3 by 18:00. Finally, the UV Index returns to its morning low of 1 by 19:00, marking a safe end to sun exposure for the day.
