re: the Gosford to Lord Howe yacht race
This is the latest sea surface
topography map that we have.
It was made from radar
altimeter measurements by
US and European satellites.
A high in the sea surface is
analogous to a high pressure on
a weather map -- currents and
winds flow anticlockwise
around them.
The maps, I feel, sometimes
underestimate the currents and
also broaden them somewhat.
Expect currents of 3 knots near
Smoky Cape, decreasing south-
ward to 2 knots, until on the
eastern side of the high where
currents will be 1-2 knots.
