These months are categorized as having an extreme exposure level, with a rapid burn time of just 10 minutes, posing substantial risks for skin damage. Conversely, from April to August, the UV Index decreases, transitioning to high and moderate levels, allowing for longer exposure times of 25 to 30 minutes before burning occurs. Notably, September presents a spike back to a very high index. Given these trends, it is advisable for visitors and residents to exercise increased caution during high-risk months (particularly January, February, March, October, November, and December) by wearing protective clothing, applying broad-spectrum sunscreen, and seeking shade during peak hours.
