Throughout the year, UV Index levels in the region indicate a significant variation in sun exposure, with the highest risk months being January to April, all categorized as extreme with an index of 16 and a burn time of only 10 minutes. As the season progresses into June and July, the index drops slightly to very high levels of 8 and 10, allowing for a marginally longer burn time of 15 minutes. However, as we transition back into the late summer months of August and September, the UV exposure spikes again to extreme levels of 12 and 13, with a return to the abbreviated burn time of 10 minutes. The challenge continues into the late fall and winter months, where the UV Index remains high, ranging from 14 to 15. Given this data, it is crucial for both visitors and residents to take protective measures against UV exposure year-round, particularly during these high-risk months, by wearing sunscreen, protective clothing, and limiting sun exposure during peak hours.
