Understanding the UV Index is crucial for residents of Woodham Mortimer, United Kingdom, where our Cfb climate can lead to varying levels of sun exposure throughout the year. Monitoring these UV levels is vital for preventing sunburn and maintaining healthy skin, especially during the higher readings around midday—reaching peaks of 7 from 12:00 to 14:00. With typical cloudy weather often misleading us about potential sun damage, staying informed about daily UV fluctuations can help you enjoy the outdoors safely while protecting your skin from harmful rays.

The sun reaches its zenith at 12:00, hitting a high of 7, where protective measures become essential. This level remains steady until 14:00, when it generates a consistent warning. The afternoon offers a gradual decline; by 16:00, it drops to 4, and the light softens as evening approaches, settling back at 2 by 18:00 and returning to its early morning calm of 1 by 19:00. Whether you’re lounging in the sun or enjoying a late afternoon stroll, always stay sun-safe!
