Merewether Tide Generation Now Online
It's not just the tides for Merewether but its the tides for Newcastle (which, lets face it, is pretty close). So you could use it for Stockton, Nobbys, Newcastle Beach, Bar Beach / Cooks Hill, Dixon Park Beach, etc.
The Merewether Tides are generated using data massaged from the brilliant program XTide written by Dave Flater.
The tide times are just indicative tides times so please don't rely on these tides for navigation (use a GPS instead :-) , sorry ).
