The UV Index exhibits significant variation throughout the year, peaking between March and October when exposure levels reach extreme categories (index values of 12 and above). The highest UV Index readings occur in May and July, both at 15, marking these months as particularly high-risk for sunburn, with a burn time of just 10 minutes for unprotected skin. January and February are also notable, with very high indices of 8 and 9 respectively, where the burn time is slightly longer at 15 minutes. Contrastingly, the risk decreases during the latter part of the year, with November holding a very high index of 9 and December dropping to a more moderate 7. Visitors and residents are strongly advised to take precautions during high-risk months: seek shade, wear protective clothing, and apply sunscreen regularly, especially between March and October when UV exposure is most intense.
