With the region's warm, sunny climate, recognizing UV levels helps in preventing sunburn and safeguarding skin health, ensuring you enjoy the beautiful outdoors safely.

Seasonal variations in UV exposure highlight significant health risks throughout the year. The highest UV Index values occur from March to October, with April, May, and June reaching an extreme level of 13 to 14 and a dangerously short burn time of just 10 minutes. Visitors and residents should be particularly cautious during these months, especially from March to July, when prolonged exposure can lead to severe skin damage. High-risk months for UV exposure are thus March through October, requiring effective sun protection measures such as applying broad-spectrum sunscreen, wearing protective clothing, and seeking shade during peak hours. As the year progresses into November and December, UV levels decrease, but individuals should still remain mindful, especially during November's very high index of 9 and December's high index of 7, to ensure consistent skin safety.
