With moderate exposure levels in January and February (UV Index 3-4), individuals can safely enjoy outdoor activities with a burn time of 30 minutes. As we move into March, the UV Index reaches a high level of 6, reducing burn time to 25 minutes, and continues to escalate through April and May, where it peaks at very high levels of 9, necessitating a burn time of just 15 minutes. The extreme risk months of July and August, with a UV Index of 11, emphasize the need for heightened sun protection, allowing only 10 minutes of unprotected sun exposure. The UV Index decreases again in September to 9, remains at 6 in October, and returns to moderate levels in November and December. To ensure safety, visitors and residents should adopt protective measures—such as sunscreen and clothing—during the high-risk months of April through August, particularly on the most intense days when UV levels peak.
