In Bottineau, United States, awareness of the UV Index is crucial for maintaining healthy skin and preventing sunburn. Understanding the UV levels throughout the day not only helps residents and visitors protect themselves but also promotes long-term skin health. With Bottineau’s Dfb climate, the region experiences varying UV exposure risks, especially during the summer months when the index peaks—a notable 8-9 from late morning to early afternoon. Staying informed can make all the difference in enjoying the sun safely!
As the sun rises, the UV Index creeps up from a mild 1 at 07:00 and 08:00, indicating a low risk for skin damage. By 09:00, it bumps up to 2, still manageable, but the midday sun packs a punch! At 10:00, the index reaches 4, and by 11:00, it skyrockets to 6, signaling that it's time to find some shade. The peak occurs at 12:00, with an impressive 8, and the intensity remains high at 13:00 and 14:00, both hitting 9. As the afternoon transitions, the numbers gradually decline; by 15:00, it decreases to 8, then 6 at 16:00, and continues to slip to 5 by 17:00. As we head into the evening, the UV Index settles back to a gentle 3 at 18:00, and finally winds down to 2 by 19:00, marking the end of a sun-soaked day. Remember to protect your skin during those peak hours!

Throughout the year, the UV Index experiences significant seasonal changes, particularly peaking in the late spring and summer months. April to August are identified as high-risk months, with UV Index values reaching as high as 9, categorized as very high, indicating a burn time of just 15 minutes. Visitors and residents are strongly advised to take protective measures during these months, such as wearing sunscreen, sunglasses, and protective clothing, especially during midday hours when the sun's rays are most intense. From September to October, the risk decreases but remains moderate, so continued sun protection is recommended.
