Throughout the year, UV Index levels show significant seasonal changes that influence sun exposure and risk of skin damage. Winter months (January and December) present a low UV Index (2), allowing for extended sun exposure without immediate risk, while February and October transition to moderate risk (3-4), necessitating cautious sun practices. As spring arrives, particularly in March and April, the UV Index rises to moderate and high (5-6), emphasizing the need for protective measures. The summer months (May through August) peak with very high levels (8-9), where a mere 15 minutes of unprotected exposure can lead to burns; thus, residents and visitors are strongly advised to wear sunscreen, seek shade, and wear protective clothing during this time. As autumn approaches, the risk decreases again, with September reverting to high, and levels gradually declining in the subsequent months. Overall, vigilance is essential during the high-risk summer months, while spring and fall call for moderated sun safety measures.
