Understanding the UV Index is crucial for residents in Machang, China, as it provides essential information on sun exposure risks throughout the day. With peak UV levels soaring to 14 around noon, being aware of these fluctuations can help you protect your skin from harmful effects like sunburn and long-term health issues. Machang's Cwb climate, characterized by a humid subtropical environment, intensifies UV exposure, particularly in the summer months. Knowing when to seek shade or apply sunscreen can make all the difference for your skin health and overall well-being.
At 07:00, the UV Index begins at a gentle 1, making it a safe time for outdoor activities. As the sun climbs higher, it peaks dramatically at 14 by 12:00, signaling a critical time for sun exposure where protective measures are essential. This intense level of UV radiation prevails through 1 PM, before gradually tapering off, descending to 10 by 3 PM and further dropping to 1 by 6 PM. The sharp rise and gradual decline create a clear window for sun safety, making it crucial to stay mindful of UV exposure during the midday hours when the risk is substantially higher.
