Understanding the UV Index is essential for residents and visitors in Rumphi, Malawi, where the sun's intensity can reach hazardous levels, particularly during the midday hours. With peak UV levels soaring to 12 around noon, it is crucial to be informed about UV exposure to prevent sunburn and protect overall skin health. Rumphi's climate, characterized by its humid subtropical conditions, can lead to prolonged outdoor activities, inadvertently increasing the risk of UV-related harm. By staying aware of UV Index readings throughout the day, you can enjoy the beautiful outdoors while keeping your skin safe and healthy.
As the sun rises, the UV Index starts off mild at 1 at 07:00, but it quickly gains intensity as the day progresses. By 09:00, it escalates to 6, signaling that sun protection is becoming essential. The peak occurs at 11:00 and 12:00, where the index reaches a striking 12, representing a high risk of harm from unprotected sun exposure. Fortunately, the intensity begins to wane after 13:00, dropping to 10 and continuing its descent throughout the afternoon. By 16:00, it falls to a negligible 1, and the UV exposure dwindles to 0 by 18:00 and 19:00. It's a day to enjoy the sun but remember to stay protected during those peak hours!
