Understanding the UV Index is crucial for residents of Dysart, Australia, where the combination of a semi-arid climate and ample sunshine can lead to significant ultraviolet radiation exposure. During peak hours, particularly between 11:00 AM and 1:00 PM, the UV Index can soar to levels of 7, indicating a high risk of harm from unprotected sun exposure. Being aware of these levels is essential for preventing sunburn and maintaining long-term skin health. By monitoring the UV Index, you can take proactive steps to safeguard yourself and your loved ones against the risks posed by the sun, especially in a region known for its sunny days and intensified UV radiation.
As the sun rises, the UV Index remains low at 1 from 07:00 to 08:00, offering a gentle start to the day. However, as the hours progress, the intensity increases, reaching 3 by 09:00 and peaking at 7 between 11:00 and 13:00. This midday surge signifies the sun's powerful rays, urging everyone to take precautions for skin protection. As the afternoon wanes, the UV Index begins to decline, dropping to 5 at 14:00, and further decreasing to 3 by 15:00. The evening brings relief, with the index falling to 1 by 16:00 and 0 from 18:00 onward.
