NYCkayaker Current tables

[mark handy]

The annual Eldridge (yellow book available at marine and paddling stores) has current predictions for a few key locations, plus offset tables that let you derive predictions for other locations.

The federal government has similar data on line at http://www.tidesandcurrents.noaa.gov.

This site has similar data, supposedly less reliable but with fun graphing options:  http://tbone.biol.sc.edu/tide.  Be sure to use the locations with "current" in the name.

Knowing the difference in theory is not enough. Where can one find tide chart that has tide CURRENT information??? 
  
When I used to paddle in San Francisco Bay, the tide chart has TWICE as many columns: besides time of high/low tide and tide height, there's also time for slack and max current AND strength... I've NOT been able to find that for the Hudson at most locations we paddle! 
  
Even with the uncertainty that's affected by weather such as rain fall and snow melt, the tide CURRENT chart would at least get you closer to the real current.

Here's a really simple explanation about tides vs currents:

Hi All-

 tide and low tide are not simultaneous with the
change of current from
 ebb to flood...

I always find that most people don't know the
difference between tides (vertical movements of the
water) and currents (horizontal movement).

I have read Craig Poole's excellent article in the
HRWA guide, and have heard it said by Steve Stanne of
NYS DEC in  apresentation.

Two diffrerent things, related of course, but on their
own timetables.

When you get used to paddling on the Hudson, you
really need to know what happens. Or you get stuck
paddling into a current, which isn't the end of the
World...  or World's End?

See ya-
