The UV Index displays extreme levels from January to April, maintaining high values through much of the year, particularly in the high-risk months of February and March, which experience a peak UV Index of 16. As spring transitions into summer, the UV Index slightly decreases to 10 in June and July, classified as very high, yet remains a concern. In late summer and early autumn, the index fluctuates between 12 and 14 before returning to 15 in December. Visitors and residents are advised to take precautions during these high-risk months—especially from January to April and February to March—by wearing protective clothing and using sunscreen with a high SPF, as burn times are notably short at just 10 minutes during most of the year. Staying informed and protected against UV exposure is essential for maintaining skin health in this region.
