Understanding the UV Index is crucial for residents and visitors of Monasterio de la Sierra, Spain, where the climate often falls within the Cfb zone, known for its mild temperatures but still posing a significant risk of UV exposure. During peak hours, especially between 12:00 PM and 3:00 PM, the UV Index can soar to levels 10 and 11, indicating a high risk of harm from unprotected sun exposure.
