As the seasons change, so does the UV Index, which plays a crucial role in sun safety for visitors and residents alike. During the winter months, like January and December, the UV levels are at a low risk (Index 2), allowing for longer burn times of 45 minutes. February sees a moderate increase (Index 4), with a reduced burn time of 30 minutes. As spring transitions into summer, the UV Index spikes tremendously between April and August, reaching a maximum of 10 (very high) with a burn time of only 15 minutes, making these months particularly high-risk for sunburn. September still poses a threat with an Index of 8 before it begins to decrease again in October (Index 6) and November (Index 4). To ensure safety, it is advised that individuals take precautions, such as wearing sunscreen and protective clothing, especially during the peak months of April to September, when the risk of UV exposure is at its highest.
