Alan, Is it possible that the streaming is live during the day and recorded playback at night? This is the first time that I have viewed the above three websites at night, as I thought there would be nothing to see in the darkness. I was quite surprised to see illuminated imagery. During the day, however, the Sun seems to be in approximate sync with the time, especially at sunset. Avila Beach is Surfline also. When you click to full screen, a brief message states that you are on Surfline.com.
