As the seasons change, so does the UV Index, which significantly influences sun safety for both visitors and residents. During the winter months of January and December, UV levels remain low (Index 2), allowing for longer safe exposure times of 45 minutes. Moving into spring, February sees a moderate increase (Index 4) that reduces burn time to 30 minutes, escalating to a high level in March (Index 6) with a 25-minute burn time. The summer months of April through August present the highest risk, as the UV Index peaks at 10 during June, July, and August, necessitating protective measures with a dangerously short burn time of only 15 minutes. In fall, September's UV Index drops to 7 (high), offering 25 minutes of safe time, and October and November see moderate levels (Indexes 5 and 3, respectively) with burn times of 30 minutes. It is essential for everyone to stay informed, taking proactive measures like wearing sunscreen, protective clothing, and seeking shade, especially from April to August, when UV exposure is at its most harmful.
