In Xiaohu, China, being aware of the UV Index is crucial for protecting yourself and your loved ones from harmful sun exposure. Understanding UV levels is vital not only for preventing painful sunburn but also for maintaining long-term skin health. With a Cfa climate that boasts warm summers and significant sun exposure, the UV Index can reach dangerously high levels—peaking at 13 during midday. By staying informed about the daily UV Index, you can make smart choices about when to enjoy the outdoors while safeguarding your skin from potential damage.
The UV Index paints a striking picture of the sun's intensity throughout the day. At 7:00 AM, the day begins with a moderate level of 2, gradually rising to 4 by 8:00 AM.

After this zenith, the index begins to dip, dropping to 12 at 1:00 PM and 9 by 2:00 PM. As the afternoon progresses, the numbers decline further to 6 at 3:00 PM, then down to 4 at 4:00 PM. The evening brings a gentle decrease, with the UV Index falling to 1 by 6:00 PM and finally reaching 0 by 7:00 PM.

Throughout the year, UV radiation levels demonstrate significant seasonal variation, peaking during the summer months. High-risk months for UV exposure are March through September, where the UV Index consistently falls within the extreme category, necessitating minimal safe exposure times of just 10 minutes. February, October, and November follow with their very high UV Indexes, allowing slightly longer safe exposure of 15 minutes. Visitors and residents are advised to take precautions during these high-risk periods, including wearing protective clothing, applying broad-spectrum sunscreen with a high SPF, and seeking shade during peak sunlight hours, typically between 10 AM and 4 PM. As UV levels drop in January and December, individuals should remain vigilant but can enjoy slightly longer burn times of 25 minutes.
