In Baimasi, China, understanding the UV Index is crucial for protecting your skin and overall health. The UV Index provides essential information about the strength of ultraviolet radiation, helping you gauge when it's time to seek shade or apply sunscreen to prevent painful sunburns and long-term skin damage. With a humid subtropical climate classified as Cfa, Baimasi experiences significant UV exposure during the peak hours of 10 AM to 2 PM, when UV levels can soar to 12—a level that calls for immediate sun safety measures. Staying informed about the UV Index is your first line of defense against the harmful effects of the sun!
As the day unfolds, the UV Index climbs steadily, starting from a gentle 1 at 07:00. By 08:00, it reaches a moderate 3, signaling the first hints of sun exposure. The intensity increases sharply, hitting 5 by 09:00 and peaking at a robust 12 during the midday hours of 12:00 and 13:00. This is a crucial time for sun protection! As the afternoon wears on, the index gradually declines, dropping to 10 at 14:00 and tapering off to 7 by 15:00. By the evening, the level returns to a more manageable 1 by 18:00, marking the end of the intense UV exposure for the day. Stay vigilant and protect your skin during those peak hours!
