Understanding the UV Index is crucial for residents of Takaishi, Japan, as it serves as a vital indicator of solar ultraviolet (UV) radiation levels. With soaring peaks reaching 11 around midday, awareness of UV levels is essential for preventing sunburn and protecting skin health. Takaishi, characterized by its humid subtropical climate, experiences heightened UV exposure during summer months, making it important for locals to stay informed and take precautions against the risks associated with prolonged sun exposure. Stay safe and protect your skin by tracking the UV Index daily!
The UV Index throughout the day reveals a dramatic rise in sun intensity, peaking during the late morning to early afternoon. Starting the day at a modest 2 at 7:00 AM, the index climbs steadily, reaching 11 by 11:00 AM and maintaining that level until 1:00 PM. This signifies a high risk of harm from unprotected sun exposure. Following this peak, the index begins to dip, dropping to 8 by 2:00 PM, and continuing its decline until it falls to 0 by 7:00 PM. With this information, it's crucial to take sun safety precautions—especially during the hours when the UV Index is at its highest!
