Understanding the UV Index is crucial for residents and visitors of San Jose del Jagueey, Mexico, where the sun's rays can be particularly intense due to its BSk climate. Being aware of UV levels helps in preventing skin issues, including painful sunburns and long-term skin health problems. In this beautiful coastal town, the UV Index can soar—reaching a staggering 14 at peak hours—making it essential to take protective measures during the day. By keeping an eye on the UV Index, you can enjoy the sun safely while safeguarding your skin against its harmful effects.
The UV Index throughout the day tells a compelling story of rising sun intensity. Starting off at a mellow 1 at 07:00 AM, it gradually increases to a moderate 2 by 09:00 AM. As the clock strikes 10:00 AM, the index soars to 5, marking the onset of stronger rays. With the sun at its peak, the index reaches an impressive 11 at 12:00 PM and 14 at 1:00 PM, signaling the highest risk for unprotected skin. Although it remains high at 14 from 1:00 PM to 2:00 PM, it soon begins to dip, falling to 9 by 4:00 PM and further down to 3 at 6:00 PM. As daylight dims, the UV Index retreats to a safe 1 by 7:00 PM, reminding us of the sun's powerful influence during the midday hours. Be sure to protect your skin when the index is at its highest!
