Understanding the UV Index is crucial for residents and visitors in Bella Vista, Mexico, where the sun shines brightly, particularly in the Aw climate zone. With UV levels peaking sharply between 11 AM and 2 PM, knowing when to seek shade can be a game-changer for sunburn prevention and long-term skin health. High UV exposure poses significant risks, making it essential to stay informed about daily UV levels. By staying aware of the UV Index, you can enjoy Bella Vista's beautiful weather while protecting your skin from harmful effects.
As the sun rises, the UV Index starts off low at 1 around 7:00 AM and 8:00 AM, making for a relatively safe start to the day. However, as the clock ticks toward mid-morning, intensity ramps up dramatically from 4 at 9:00 AM to a peak of 14 by 1:00 PM. This is the moment of maximum solar exposure, with the index hitting 13 at 12:00 PM and slightly declining to 11 by 3:00 PM. As the day winds down, the UVI falls steadily, dipping back to 1 by 7:00 PM. If you're planning outdoor activities, prioritize protection during those critical hours between 10:00 AM and 3:00 PM when the sun packs the most punch!
