In Mornington, New Zealand, being aware of the UV Index is essential for maintaining skin health and preventing sunburn. Understanding UV levels helps residents and visitors alike make informed decisions about sun exposure throughout the day, especially as the risk of harmful UV radiation can rise even in the moderate climate of the Cfb zone. Typically, from 9:00 AM to 4:00 PM, UV Index levels in Mornington remain low, ranging from 1 to 1, but even minimal exposure can accumulate over time, emphasizing the importance of protective measures for skin health. Stay informed and enjoy the sun safely!
Throughout the day, the UV Index exhibits a distinct pattern, with the sun's intensity gradually increasing as the hours progress. From 07:00 to 08:00, the UV Index remains at a low level of 0, indicating minimal exposure risk. However, starting at 09:00, it slowly climbs to 1, maintaining this level until 16:00. This period, characterized by a sustained UV Index of 1, suggests that while the sun is visible, precautions like sunscreen and protective clothing are still advisable, especially during midday. As evening approaches, from 17:00 onward, the UV Index drops back to 0, signaling a return to safety from the sun's rays. It's a day that reminds us to enjoy the outdoors while staying sun-smart!
