Throughout the year, UV Index levels fluctuate significantly, with the highest levels occurring during the summer months. From June to August, the UV Index reaches a maximum of 11, categorized as extreme, with a burn time of only 10 minutes. This indicates the need for increased vigilance during these months, as prolonged exposure can lead to severe sunburn and skin damage. The high-risk months are therefore considered to be March through September, particularly stark in April, May, July, and August, which consistently show very high to extreme exposure levels. Residents and visitors are advised to take precautions, including wearing protective clothing, applying sunscreen, and seeking shade, especially during peak sun hours from 10 AM to 4 PM. Conversely, during the winter months of January, November, and December, when the UV Index drops to moderate, the burn time increases to 30 minutes, allowing for more extended periods outdoors with reduced risk. Proper sun safety measures should be adjusted based on these seasonal UV changes to ensure well-being year-round.
