Throughout the year, seasonal fluctuations in UV index levels highlight the importance of sun safety for both visitors and residents. The high-risk months occur in January, February, November, and December, where UV indices reach extreme levels (up to 14), resulting in a burn time of just 10 minutes. March and October also present considerable risk with very high levels (UV index of 9) and a burn time of 15 minutes. As the year progresses into April and September, while the UV index drops to high (7 and 6, respectively), exposure remains risky, with burn times of 25 minutes. From May to August, the UV index reaches moderate levels (4 and 3), allowing for safer sun exposure but still warrants caution. It is essential for everyone to protect their skin during these times by seeking shade, wearing protective clothing, and applying sunscreen to mitigate the risks associated with UV exposure.
