Understanding the UV Index is crucial for residents of Kowloon, Hong Kong, where intense sun exposure can pose significant health risks. With a humid subtropical climate typical of the region, Kowloon experiences high UV levels, particularly from late morning to early afternoon, when the index peaks at an alarming 14. Being aware of these UV levels is essential not only for preventing sunburn but also for maintaining long-term skin health. As the sun's rays can be particularly harsh, especially during the summer months, staying informed can help safeguard against the damaging effects of ultraviolet radiation.
As the sun rises, the UV Index begins its ascent, starting from a gentle 1 at 07:00. By 08:00, it climbs to 3, signaling the need for increased sun protection. The intensity peaks dramatically at 12:00 with a scorching 14, marking the most hazardous sun exposure period of the day. Just before noon, at 11:00, the UV Index hits 12, a warning to stay in the shade. By 14:00, it begins its descent, dropping to 11 and continuing down to a mild 4 by 16:00. The evening brings relief as the index falls to 0 by 19:00, allowing for a safe outdoor experience as the sun sets. Stay aware and protect your skin during those peak hours to enjoy your day safely!
