Understanding the UV Index is essential for residents and visitors in Canh Nang, Vietnam, where the tropical climate brings both beauty and UV exposure risks. With peak UV levels reaching up to 13 from 11:00 AM to 1:00 PM, being aware of these fluctuations is crucial for effective sunburn prevention and maintaining skin health. The Cwa climate in Canh Nang means that UV radiation can be particularly intense during sunny days, making it vital for everyone to monitor daily UV Index updates and take appropriate sun safety measures to protect themselves from harmful effects.
The UV Index throughout the day showcases a striking pattern of intensity, peaking sharply around 11:00 AM and 12:00 PM with a robust 13, signaling a high risk for sun exposure during these hours. Early morning starts gently at 2 at 7:00 AM, then steadily climbs, passing through moderate levels at 8:00 AM and 9:00 AM, before reaching a critical point with a 10 at 10:00 AM. Post-noon, the index gradually declines, dropping to 6 by 3:00 PM and further to a much safer 1 by the evening at 5:00 PM and 6:00 PM, where it ultimately settles at 0 by nightfall. To enjoy the sun while protecting your skin, plan outdoor activities early or enjoy them after the peak hours!
