Understanding the UV Index is crucial for residents and visitors in Otlamalacatl, Mexico, where solar radiation can be intense due to the region's Cfa climate. As the sun reaches its peak, UV levels can soar, exceeding safe exposure limits and increasing the risk of sunburn and long-term skin health issues. By being aware of daily UV fluctuations, particularly during the midday hours when values can reach a maximum of 13, you can better protect your skin and enjoy the beautiful outdoor environment safely. Whether you're hiking, relaxing at the local parks, or simply spending time outdoors, knowing the UV Index empowers you to make informed choices about sun protection and health.
The UV Index forecast reveals a steady rise in UV radiation throughout the morning, peaking at an intense 11 by noon. From 07:00 to 09:00, levels remain low, hovering around 1 to 2, making it a safe time for early outdoor activities. As the sun climbs higher, the index escalates sharply, reaching a notable 13 between 13:00 and 14:00, indicating a high risk of harm from unprotected sun exposure. A gradual decline follows, with values easing back down to 5 by late afternoon and returning to 1 in the evening. For safety, protective measures are highly advised during the midday and early afternoon hours when UV exposure is at its peak.
