In San Rafael Matriz, Mexico, awareness of the UV Index is crucial for safeguarding your skin and overall health. The higher the UV levels, the greater the risk of sunburn and long-term skin damage, making it essential to monitor these changes throughout the day. With a BSh climate, this region faces significant UV exposure, particularly during peak hours when the index can soar to levels of 13 and 14 between 12:00 PM and 2:00 PM. Understanding these risks not only helps you plan outdoor activities wisely but also empowers you to take the necessary precautions to protect your skin under the sun's powerful rays.
As the sun rises, the UV Index starts off gently, peaking at 1 by 08:00. However, as the day progresses, the intensity ramps up significantly. By 10:00, the index reaches 5, but the real heat kicks in at 12:00, soaring to an intense 11. The peak occurs at 14:00, where it hits a blistering 14—a clear signal to seek shade and protect your skin. After this, the index begins to drop, settling at 12 by 15:00 and gradually descending to 3 by 18:00. As twilight approaches, the UV levels ease back to 1 by 19:00, marking a dramatic contrast to the midday sun's peak. Stay vigilant and wear sun protection during these critical hours!
