Woolamai Beach

["Peter Shute" pshute2]

I was recently at a conference near Phiilip Island in Victoria, Australia. 
There wasn't much daylight available outside of conference times as it's mid 
winter here, and the weather was very wet and windy, so I only managed this one 
recording of surf at Woolamai Beach:

This was recorded with my EM172/SASS rig, so I'm interested in opinions on the 
quality. In particular, an odd shifting effect at 4:00 which I'm wondering 
whether it's caused by wind in the mics, or possibly some fluke of wave 
patterns.
