Understanding the UV Index is crucial for residents and visitors of Bhattarai Danda, Nepal, where the Cwa climate brings significant sun exposure. As the sun climbs high each day, particularly between 10 AM and 1 PM, UV levels can reach a peak of 11, indicating an extreme risk of harm from unprotected sun exposure. Awareness of these levels helps in preventing sunburns and safeguarding skin health, making it essential to monitor the UV Index regularly. By staying informed, you can enjoy the beautiful surroundings while protecting yourself from the potential dangers of high UV radiation.
The UV Index throughout the day paints a vivid picture of sun exposure risk. Starting with a moderate score of 3 at 7:00 AM, it quickly climbs to a high of 11 between 11:00 AM and 12:00 PM, marking the peak intensity of sunlight. Just before noon, the UV Index reaches its height at 10, where caution is advised for prolonged sun exposure. In the early afternoon, it begins a gradual decline, moving down to 9 by 1:00 PM and tapering off to 4 by 3:00 PM. As the evening approaches, the index diminishes further, dropping to 1 by 5:00 PM, and eventually reaching 0 after 7:00 PM, signaling a safe retreat from the sun's rays. Sun safety is paramount, especially during those prime hours when UV radiation poses the highest threat!
