In Keroka, Kenya, understanding the UV Index is crucial for safeguarding your skin and overall health under the sun. With peak UV levels reaching as high as 12 during midday, awareness of these fluctuations can help prevent sunburn and long-term skin damage. Keroka enjoys a mild Cfb climate, but its geography and elevation expose residents and visitors to significant UV risks, particularly from 10 AM to 2 PM when the sun is at its strongest. Staying informed about UV levels allows you to enjoy the beautiful outdoors while protecting yourself from harmful rays.
As the day unfolds, the UV Index reveals a dynamic dance of sunlight intensity. Starting off gently at 1 during the early hours, the index climbs steadily, reaching a manageable 4 by 9 AM. The ascent peaks drastically at 12 between 12 PM and 1 PM, signaling the sun's strength at its zenith. A gradual decline begins post-lunch, with the index dropping to 7 by 3 PM, then continuing its descent to 2 by 5 PM. As daylight wanes, the UV Index returns to safe levels, resting at 1 by 6 PM and finally tapering off to 0 by 7 PM. This hourly progression highlights the importance of sun safety, particularly during midday when the UV rays are at their most potent. Remember, protection during high UV Index hours is crucial!
