Understanding the UV Index is crucial for residents of Bihorel, France, as it directly impacts skin health and sun safety. With typical UV exposure risks peaking during the sunniest hours, being aware of UV levels can help prevent painful sunburns and long-term skin damage. Bihorel's Cfb climate offers a unique blend of moderate temperatures and occasional sunny days, making it essential to monitor UV fluctuations throughout the day. From a low value of 1 in the early morning to a significant peak of 8 in the afternoon, staying informed about the UV Index can empower you to enjoy the outdoors while protecting your skin!
As the sun rises, the UV Index gradually climbs, beginning at a mild 1 around 7:00 AM and 8:00 AM. By 9:00 AM, it nudges up to 2, creating a gentle warmth. The real action starts at 10:00 AM, when the index hits 3, and by midday, at 12:00 PM, it spikes to a steamy 7. The peak hours arrive between 1:00 PM and 2:00 PM with a maximum of 8, urging sun-seekers to take extra care. As the afternoon fades, the UV Index gradually recedes: 7 at 3:00 PM, 6 by 4:00 PM, and down to 2 by 7:00 PM. Ensure you’re protected during the peak, as the sun's influence intensifies before it begins to wane!
