Understanding the UV Index is crucial for residents and visitors in Apatzingán, Mexico, where the warm Aw climate brings about high sun exposure throughout the year. Being aware of UV levels helps in effectively preventing sunburn and safeguarding skin health, particularly during peak hours when the index can soar to 12 or 13. With midday sun intensifying exposure risks, it’s essential to monitor the UV Index and take appropriate precautions to enjoy the sun safely in this vibrant region.
As the day unfolds, the UV Index rises steadily, beginning at a safe 0 at 07:00 and peaking dramatically. By 10:00, it escalates to 4, signaling the need for some sun protection. The intensity reaches 10 at 12:00, and then hits its maximum at 13:00 with a formidable 12. Right after, it slightly dips but remains high at 12 until 15:00. As the afternoon wanes, the UV Index begins to decline, dropping to 9 by 16:00, and continuing its descent to 1 by 19:00. This fluctuation highlights the importance of being sun-smart during peak hours, especially between 11:00 and 15:00, when the sun is at its strongest.
