Understanding the UV Index is crucial for residents and visitors in Tournay, France, where sunny days can lead to elevated exposure risks. The UV Index provides essential insights into sun intensity, helping you make informed decisions to protect your skin from harmful UV radiation and prevent sunburn. In Tournay's temperate climate, with its varying weather patterns, the risk of high UV levels—especially around noon—can catch many off guard. With UV levels peaking at a significant 10 during the afternoon, staying aware and taking necessary precautions is vital for ensuring your skin health throughout the sunny months.
The UV Index data reveals a dynamic sun exposure pattern throughout the day. Starting with a low index of 1 in the early hours (07:00 and 08:00), sun sensitivity increases as the day progresses.

As the afternoon wanes, the levels gradually decline, sliding to 8 at 16:00 and further down to 3 by 18:00. By 19:00, the exposure reduces to 2, suggesting a safe transition as daylight fades. Remember, when the UV Index is 6 or higher, it’s essential to take protective measures!
