Understanding the UV Index is crucial for residents of Creighton, South Africa, as it serves as a vital indicator of sun exposure risk throughout the day. With sunburn and long-term skin health at stake, becoming familiar with the UV levels can help you take necessary precautions. Creighton's mild Cfb climate can still present surprising peaks in UV radiation—especially during midday hours when the index reaches up to 5. By staying informed about local UV conditions, you can enjoy the outdoors while protecting your skin from harmful effects.
The UV Index throughout the day reveals a notable oscillation in sun exposure. Early morning hours from 7:00 AM to 8:00 AM see a mild UV Index of 1, indicating minimal risk. As the sun ascends, the intensity rises sharply, peaking at 5 between 11:00 AM and 1:00 PM, marking the day’s highest risk for skin damage. Following this peak, the index tapers off in the afternoon, returning to a manageable 2 by 3:00 PM, before descending to a safe 0 by 6:00 PM. It’s clear that the primary concern for sun safety lies during mid-day; ensure to protect your skin when the UV Index hits its zenith!
