Throughout the year, the UV Index exhibits notable seasonal variations, peaking during the summer months. January and February present a high risk with a UV Index of 6, allowing for only 25 minutes of exposure before burns occur. As we transition into March and April, the risk escalates to a very high category (UV Index 8-10) with a reduced safe exposure time of 15 minutes. This trend continues into May before reaching its most critical peak in June and July, where the UV Index hits 11-12, classified as extreme, allowing just 10 minutes of safe sun exposure. Both August and September maintain a similar high risk before gradually decreasing in October to 8 and November to 7, marking a transition to lower risk months, culminating in December with a moderate category (UV Index 4) and a safer 30 minutes of burn time. Given this data, it is crucial for both visitors and residents to exercise caution and prioritize sun protection during the high-risk months of March through September, especially during summer when the UV exposure can be critical.
