In General Trevino, Mexico, awareness of the UV Index is crucial for safeguarding your skin against harmful ultraviolet radiation. Understanding UV levels not only helps prevent painful sunburns but also plays a vital role in long-term skin health. With a hot semi-arid climate (BSh), residents and visitors alike must be vigilant, especially during peak hours when the UV Index can soar to 12 around noon, signaling an extreme risk of harm from unprotected sun exposure. By staying informed about local UV patterns, you can better enjoy the sunny days while protecting your skin.
At dawn, the UV Index starts low, peaking at 1 around 7:00 AM and remaining steady until 9:00 AM. As the sun climbs higher in the sky, exposure increases, hitting 4 by 10:00 AM. The intensity escalates sharply, reaching a striking 10 at 12:00 PM and peaking at 12 between 1:00 PM and 2:00 PM—the hottest moment of the day. Following this peak, the UV Index gracefully declines, dropping to 5 by 5:00 PM and further to 3 by 6:00 PM. As evening approaches, it wraps up with a return to 1 by 7:00 PM. It's a clear reminder to seek shade during peak hours and protect your skin!
