In North Fork, United States, understanding the UV Index is vital for maintaining skin health and preventing sunburn.

As the afternoon progresses, UV levels fluctuate slightly, tapering back to 8 at 3:00 PM before dropping significantly towards the evening, settling at 1 by 6:00 PM. With such a dramatic rise and fall in UV exposure, it's essential to protect your skin when the index is at its highest, particularly during those peak hours of 11 AM to 1 PM.

Throughout the year, seasonal changes in UV levels indicate varying risks associated with sun exposure. From January to April, UV Index values gradually rise from 5 (moderate) in January to 11 (extreme) in April, with February and March being notably high-risk months at 8 and 10, respectively. The peak of UV intensity occurs from May to September, where the UV Index reaches extreme levels of 12-13; hence, these months are particularly hazardous, with a burn time as low as 10 minutes. In contrast, October to December sees a decrease, with October and November presenting very high and high-risk categories, but still requiring caution with burn times of 15-25 minutes. Visitors and residents are advised to take protective measures, such as wearing sunscreen, sunglasses, and protective clothing, especially during the high-risk months of March through September to prevent skin damage.
