As the seasons change, so do the UV Index levels, which indicate the strength of ultraviolet radiation. January and February see moderate levels (UV Index 3-4), allowing for a reasonable burn time of 30 minutes. However, starting in March, the UV Index escalates into the high range at 7, and severe exposure levels are reached from April to August, where the Index peaks at an extreme level of 11 and a burn time drops to just 10 minutes. September follows with a very high level of 8, while October sees a decrease to high at 6. The year concludes with November and December returning to moderate and low levels, respectively. Visitors and residents should take precautions from March through September, particularly during the extreme months, by seeking shade, wearing protective clothing, and applying sunscreen regularly to minimize the risk of sunburn and skin damage.
