Understanding the UV Index is crucial for residents of Dagang, China, where the subtropical climate (Cfa) brings both beautiful sunshine and potential risks. With peak UV levels reaching a high of 11 around noon, awareness of UV exposure can significantly impact skin health and help prevent painful sunburns. As the sun's intensity varies throughout the day, knowing when to seek shade or apply sunscreen becomes paramount for enjoying outdoor activities safely. Stay informed about the UV Index to protect yourself and your loved ones from the harmful effects of ultraviolet radiation in Dagang's vibrant environment.
As the sun rises, the UV Index starts off low at 2 by 7:00 AM, gradually climbing to 3 by 8:00 AM. The intensity peaks dramatically by 12:00 PM, reaching an impressive 11, signaling the height of midday sun. For the next hour, the index remains robust at 10, but begins to taper off thereafter. The numbers drop to 8 at 2:00 PM, then decline further to 5 by 3:00 PM. As the day transitions toward evening, the UV levels fall to 3 at 4:00 PM, then gently descend to 1 by 5:00 PM, finally tapering off to 0 by 7:00 PM. This data highlights the importance of sun safety during the peak hours between 10:00 AM and 2:00 PM, when protective measures are crucial!

As the seasons change, so does the UV Index, which indicates the strength of ultraviolet radiation. January and December feature moderate UV levels (index 4), allowing for longer exposure times of 30 minutes before burning. However, as early as February, the index rises to 6, marking the start of higher risk for skin damage with a burn time of just 25 minutes. The peak risk months occur mid-year, from June to August, when the index reaches an extreme level of 11, necessitating protective measures with a burn time of only 10 minutes. As fall approaches, September and October see a decline, though the UV Index remains very high (index 10 and 8 respectively), with 15 minutes of safe exposure. Residents and visitors should take precautions, especially during high-risk months, by seeking shade, wearing UV-blocking clothing, and applying sunscreen to minimize the risk of skin damage.
