Being aware of these UV levels helps prevent sunburns and long-term skin damage, allowing residents and visitors to enjoy the outdoors while taking necessary precautions. Prioritizing UV Index awareness in Guiren not only promotes skin health but also encourages safe sun habits in this vibrant locale where the sun shines brightly.
As the sun rises, the UV Index begins its climb, peaking at a maximum of 10 between 11:00 AM and 12:00 PM. Early bird sun-seekers see a gradual increase from 2 at 07:00 to a more pronounced 6 by 09:00. Those venturing out around 10:00 AM should be cautious, as the index hits an intense 8.
