In Villarejo de Montalbán, Spain, awareness of the UV Index is crucial for safeguarding your skin against harmful sun exposure. Understanding UV levels is essential not only for preventing sunburn but also for maintaining long-term skin health. With a Mediterranean climate characterized by hot summers, local residents and visitors alike must be vigilant, especially during peak UV times when the index can soar to 11 at midday. Staying informed about UV exposure risks can help you enjoy the beautiful Spanish sun while protecting your skin from its potentially damaging effects.
The UV Index shows a dynamic fluctuation throughout the day, starting at a mild 1 early in the morning (07:00 and 08:00) and gradually rising to a moderate 2 by 09:00.

After reaching its zenith, the index gracefully tapers off, dropping to 9 by 16:00 and ultimately settling at a more manageable 2 by 19:00. It’s a day that demands attention to sun safety, particularly in the peak hours!
