Understanding the UV Index is essential for residents of Evansville, where sunny days abound and outdoor activities are a way of life. With UV levels peaking at 10 during midday, it's crucial to grasp the implications for skin health and sunburn prevention. The city’s BSk climate—characterized by hot summers and moderate UV exposure—means that awareness of daily UV levels can help protect you from harmful effects. By staying informed, you can enjoy Evansville's beautiful weather while taking proactive steps for your skin's safety.
The UV Index throughout the day showcases a dynamic pattern of sun exposure, peaking during the afternoon. At 07:00, the index starts low at 1, gradually increasing as the sun rises. By 10:00, it reaches 6, signaling a rise in sun intensity, culminating in a striking 10 from 12:00 to 13:00, indicating a high risk of harm from unprotected sun exposure. As the day progresses, the UV Index declines, dropping to 3 by 17:00, and steadily returning to 1 by 19:00. This data highlights the importance of sun protection, especially during midday when the UV Index is at its highest.

As the seasons change, so do the UV Index levels, impacting sun exposure and burn times significantly. January begins with a moderate UV Index of 4 and a burn time of 30 minutes, but by April, the index escalates to an extreme level of 11, drastically reducing burn time to just 10 minutes. The highest risk months are June and July, featuring an extreme UV Index of 12 and a minimal burn time of 10 minutes, highlighting the need for caution. As summer transitions to fall, the UV Index begins to decline, with September at 9 (very high) and October back to 6 (high). November and December see moderate levels again with indices of 4 and 3 respectively, allowing for longer burn times of 30 minutes. It is essential for visitors and residents to remain vigilant during high-risk months (April through September), utilizing sunscreen, protective clothing, and limiting sun exposure during peak hours to ensure safety while enjoying the outdoors.
