The high-risk months are therefore January, February, March, September, October, November, and December when exposure can lead to severe sunburn quickly. Visitors and residents should exercise extreme caution during these periods, seeking shade and wearing protective clothing. As spring approaches, the UV Index gradually decreases to very high levels in April and August, followed by a shift to high in May and July, where burn times increase slightly but still require vigilance. June offers a brief respite at moderate levels, allowing for more extended outdoor activities, though sun safety should still be considered. Whether high or moderate, sun protection is crucial year-round to guard against harmful UV radiation.
