In Tieshan, China, awareness of the UV Index is paramount for maintaining skin health and preventing sunburn, especially as the Cfa climate brings a mix of humidity and sunlight. Understanding UV levels helps residents and visitors alike to make informed decisions about sun protection, particularly during peak hours when the index reaches a maximum of 13 around noon. With the risk of harmful UV radiation being highest during midday, knowing when to seek shade or apply sunscreen can significantly reduce the chances of skin damage. Embrace the sunshine while staying safe in Tieshan!
The UV Index data reveals a striking daily rhythm of sun exposure, peaking dramatically around noon. Starting at a modest 2 at 07:00, the index climbs steadily, crossing 4 by 08:00 and reaching a noteworthy 6 at 09:00. As the sun rises, it hits a staggering 10 at 10:00, culminating in a maximum of 13 by 12:00—a clear indication that this is the moment of highest sun intensity. The index begins to taper off, falling to 10 by 14:00, then declines further to 6 at 15:00 before dropping steadily to 2 by 17:00. As twilight falls, UV levels plummet to 1 by 18:00 and vanish entirely by 19:00. This data serves as a critical reminder to embrace sun safety practices during the peak hours of 10 AM to 2 PM when UV exposure is at its highest.

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.
