Understanding the UV Index in Ntfonjeni, Eswatini is crucial for safeguarding your skin and overall health. This index provides vital information about the intensity of ultraviolet radiation, helping residents and visitors alike to gauge sun exposure risks throughout the day. With a typical Cwa climate characterized by warm summers and a notable midday sun, awareness of UV levels can help prevent sunburn, reduce skin damage, and lower the risk of long-term health issues. During peak hours, particularly from 11:00 to 12:00, the UV Index can reach levels of 6, prompting the need for protective measures. Stay informed, stay safe, and enjoy the beautiful sun of Ntfonjeni responsibly!
The UV Index starts low in the early morning, with a maximum of 1 at 07:00 and 08:00, making it a safe time for outdoor activities. As the day progresses, the intensity rises sharply, peaking at 6 between 11:00 and 12:00—the perfect time to take precautions if heading outside. By 13:00, it dips slightly to 5, and a more noticeable decline occurs in the afternoon, falling to 2 by 15:00. As the sun sets, the UV Index drops off sharply, reaching 1 by 16:00, and finally 0 past 18:00. It’s clear that midday sun calls for some sun safety measures, but the later hours provide a much more forgiving environment for enjoying the outdoors!
