In Giridih, India, being aware of the UV Index is essential for protecting your skin and maintaining overall health. With high levels of UV radiation peaking around midday, understanding these levels can help prevent sunburn and reduce long-term skin damage. With a Cwa climate characterized by hot summers and significant sunlight exposure, residents and visitors alike should be vigilant about the potential risks of UV rays.
