Re: [Paddlewise] Translating Tides Into Currents Around Islands and Estuaries

Tom,

The NOAA folks have also set up a Real Time current system for selected
ports and waterways around the U.S.  New York/New Jersey area is one of
those areas.  You can see charts of recorded vs. projected readings for the
past three days and other features.  Check it out at:

Hopefully you'll be hearing also from those with applied local knowledge.

little I know about currents, being a newbie, I understand that around
islands and such the currents may not be so easily decerned simply from the
tide table.  For instance, I live in Brooklyn, NY, and plan to paddle around
the local area.  Brooklyn is at the western end of a large island (Long
Island, ~120 miles x ~20 miles).  Then there is Manhatten Island which has
the Hudson River flowing south on it's west side, open to the ocean to the
south, and open to Long Island Sound over to the east but those currents are
diverted by the relatively small Randall's island.   And Staten Island is
here also.  So the tides may be coming from different directions at slightly
or more than slightly different times plus the effects of the river.  So now
how does one figure out the currents? I've heard the currents around some of
the necked down parts can hit 8 knots and form whirlpools.  Is it just a
matter of gaining lo!
