Throughout the year, UV index levels experience notable fluctuations, with high-risk months primarily occurring from March to September. During this period, particularly in April, May, June, July, and August, the UV index reaches very high levels (9 to 10), indicating a significantly increased risk of harm from unprotected sun exposure, with a burn time as short as 15 minutes. It is crucial for both visitors and residents to take proactive measures, such as wearing sunscreen, protective clothing, and seeking shade during peak hours, especially from late spring to late summer. In contrast, the UV index drops to moderate levels in the winter months (January, February, November, and December), allowing for longer burn times of 30 minutes and a lower overall risk. Regular UV index monitoring is advisable to stay aware of risks throughout the changing seasons.
