Understanding the UV Index is crucial for residents and visitors of Martin de Yeltes, Spain, where the Mediterranean climate can lead to varying levels of sun exposure throughout the day. With UV levels peaking at 10 around midday, awareness of these numbers is vital for preventing sunburn and protecting skin health.
