Understanding the UV Index is essential for residents of Feltham, United Kingdom, where varying levels of sunlight can significantly impact skin health. Being aware of UV levels helps you prevent sunburn and reduces the risk of long-term skin damage. Feltham experiences a temperate maritime climate (Cfb), which means even on overcast days, UV radiation can be deceptively strong. With maximum UV Index values peaking at 8 during midday, it's crucial for locals to stay informed and take precautions against harmful exposure. Whether you're enjoying a sunny day outdoors or simply commuting, understanding the UV Index is key to protecting your skin year-round.
As the sun rises, the UV Index begins its ascent, starting at a mere 1 at 7:00 AM. By 8:00 AM, it climbs to 2, but it’s by 9:00 AM that we see a moderate rise to 3. The intensity peaks between 11:00 AM and 1:00 PM, hitting a high of 8, indicating that sun protection methods should be in full swing. As the afternoon progresses, values slightly decrease, with the UV Index dropping to 6 by 3:00 PM and then gradually retreating to 1 by 7:00 PM. This hourly data serves as a reminder to stay vigilant about sun safety during the mid-day hours when UV exposure is at its highest.
