Throughout the year, UV levels vary significantly, highlighting the importance of sun safety during certain months. The high-risk period spans from March to September, during which the UV Index reaches very high to extreme levels—notably peaking at 12 in May and June. The burn time decreases sharply, particularly in April, where a mere 10 minutes of unprotected exposure can result in skin damage. For visitors and residents, it is crucial to take protective measures such as applying sunscreen, wearing protective clothing, and seeking shade, especially during these high-risk months. In contrast, January and December present a lower risk with moderate UV conditions, where a burn time of 30 minutes provides a buffer for skin protection. Stay informed, and enjoy the sun safely!
