In Strong, United States, being aware of the UV Index is essential for protecting your skin and promoting overall health. Understanding the UV levels throughout the day can help you prevent sunburn and reduce the risk of long-term skin damage. With a Cfa climate, residents often experience strong sunlight, reaching peaks of 11 on the UV Index scale during midday hours. By paying attention to these levels, you can enjoy the outdoors while safeguarding your skin from harmful UV radiation.
The UV Index throughout the day presents a clear peak in intensity, starting off quite low at 07:00 with a value of 1. As the morning progresses, the index steadily climbs, reaching 6 by 10:00 and hitting its maximum at 11 around 13:00. This period marks the sun's strongest influence, showcasing a peak UV index of 10 at 12:00. After this high point, the index begins to decline, tapering to 8 by 15:00, then down to 4 at 17:00, and finally retreating back to 1 as evening draws near at 19:00. This pattern highlights the importance of sun protection during the midday hours when UV exposure can be particularly intense.

As the seasons change, so does the UV Index, which significantly impacts sun exposure and the risk of skin damage. January and December are generally safer months with a moderate exposure category (UV Index 4), allowing for about 30 minutes of burn time. However, by February, the risk rises to high (UV Index 7) with a burn time of 25 minutes. The peak risk occurs from March to August, where the index reaches extreme levels (UV Index 10-12), allowing only 10 minutes of sun exposure without protection. High-risk months also include April and May, which feature very high to extreme categories. September and October still present significant risks with very high levels (UV Index 8-9). For the safety of residents and visitors, it is crucial to wear sunscreen, seek shade, and limit sun exposure during these high-risk months, particularly from late winter through summer.
