In Kilometro 30, Mexico, being aware of the UV Index is crucial for safeguarding your skin against harmful ultraviolet rays. Understanding UV levels not only helps prevent painful sunburns but also plays a vital role in long-term skin health. In this region, characterized by its Aw climate, the UV exposure can be intense, particularly during midday hours when indices can peak at a staggering 14. With this knowledge, residents and visitors alike can take proactive measures to enjoy the sun safely, ensuring both fun and protection under the vibrant Mexican sky.
The UV Index for the day reveals a clear pattern of increasing intensity as the sun climbs higher in the sky.

This midday heat marks the highest risk for sun exposure, with a staggering 11 seen at 12:00 and 13 at 13:00.
