Understanding the UV Index is crucial for residents of Clinton, United States, where the climate can lead to elevated levels of ultraviolet radiation. Being aware of UV levels helps you take proactive measures to protect your skin from harmful sunburns and long-term health issues. On sunny days, particularly around noon when the UV Index peaks at 10, the risk of overexposure increases significantly. With a humid subtropical climate (Cfa), Clinton experiences varying UV exposure throughout the year, making it essential to stay informed. Prioritizing UV safety not only helps safeguard your skin but also enhances your overall well-being as you enjoy the great outdoors.
The UV Index shows a notable progression throughout the day, beginning at a minimal level of 1 at 07:00. As the sun climbs higher, the index escalates, peaking at an impressive 10 between 13:00 and 14:00—the height of sun exposure. The morning hours see gradual increases, reaching 8 by 11:00, while 12:00 features a 9, signaling a strong need for protection against harmful rays. Following the peak, the index begins to gently decline, dropping to 6 by 16:00 and down to 3 by 17:00, before winding down to 1 again by 19:00. This data serves as a crucial reminder that midday sun protection is essential for safety during the hours when UV rays are at their strongest.
