Seasonal UV changes reflect a marked increase in UV Index values during the spring and summer months, peaking in April, May, and July with an Index of 14 marked as extreme. The highest UV readings occur from February to October, with March and April also seeing values of 13 to 14, indicating a high risk of harm from unprotected sun exposure. Visitors and residents are strongly advised to take precautions during these high-risk months—especially from February through October—by wearing protective clothing, applying broad-spectrum sunscreen, and seeking shade between 10 AM and 4 PM.
