In Changping, China, being aware of the UV Index is crucial for maintaining skin health and preventing sunburn. Understanding UV levels empowers residents and visitors alike to take proactive measures against harmful rays, especially during peak hours when the index can reach an alarming 12 around noon. With a Cwa climate characterized by hot summers, the risk of overexposure increases significantly. By paying attention to the UV Index, you can enjoy outdoor activities while safeguarding your skin against the damaging effects of ultraviolet radiation.
The UV Index throughout the day showcases a stark increase as the sun rises, starting from a mild 1 at 07:00 and peaking at a striking 12 between 12:00 and 13:00. This significant surge highlights the importance of sun protection, especially during the hours when the index reaches maximal levels of 10 at 11:00 and 11 at 14:00. As the afternoon wanes, the UV Index begins to decline, dropping to 8 by 15:00 and finishing the day with a gentle return to 1 by 19:00. This data serves as a crucial reminder to prioritize sun safety during midday hours when UV exposure is at its highest.
