Understanding the UV Index is essential for residents of Del Rey, United States, where sunny days and warm temperatures are common features of the Mediterranean climate (Csa). Awareness of UV levels helps you prevent sunburn and protect your skin health, allowing you to enjoy the outdoors safely. From the mid-morning peak of 10 at noon to the gradual decline in the afternoon, knowing how to interpret these readings can significantly reduce your risk of harmful UV exposure. Whether you're lounging at the beach or partaking in outdoor activities, staying informed about the UV Index is key to making mindful choices under the sun.
The hourly UV Index data reveals a dynamic shift in sun intensity throughout the day, starting from a gentle 1 at 07:00, ideal for morning strolls. As the sun rises higher, the index escalates, peaking at a potent 10 between 12:00 and 13:00. This mid-day surge emphasizes the need for sunscreen and protective gear, as the risk of harm from UV rays increases significantly. By 15:00, the index begins to decline, settling at 7 before tapering off further to a mere 1 by 19:00, signaling a safe reprieve for evening outdoor activities. Stay aware and protect your skin during those peak hours!
