Understanding the UV Index is crucial for residents and visitors in Tanshui, China, where sunlight can be both a blessing and a risk. With peak UV levels reaching as high as 13 during the midday hours, being aware of these fluctuations is essential for sunburn prevention and skin health. Tanshui’s Cwa climate brings warm summers and mild winters, resulting in significant UV exposure that can lead to skin damage if proper precautions aren’t taken. By staying informed about UV levels, you can enjoy the beautiful outdoors while protecting your skin from harmful rays.
From 07:00 to 19:00, the UV Index exhibits a pronounced peak during midday hours, soaring to 13 between 12:00 and 13:00. The intensity rises steadily from a mild 1 at 07:00 to a substantial 12 at 11:00, indicating peak sun exposure just before noon. As the afternoon progresses, the index gradually declines, dropping to 5 by 16:00 and further to a safe 1 as the sun sets. With a dramatic increase during the late morning and early afternoon, it's crucial to stay protected against UV rays, especially when the index hits 9 and above between 10:00 and 14:00.
