So tides are good this Thursday and Friday:
03-07-2008 Thu 12:33 PM IST 4.09 meters High Tide
04-07-2008 Fri 1:25 PM IST 4.10 meters High Tide
As far as I remember you need to be on the water an hour before high tide since the wave works for the 30 mins before high tide as the water rushes in the arches. Maybe it's more?
Anyway, I'll be heading out and some company would be nice
