NOAA has very little in the way of predictions on currents in the various channels around the Hawaiian Islands.
Looking at http://tidesandcurrents.noaa.gov/currents06/tab2pc4.html#151 it looks like a lot of areas have a preferred direction of current, which often happens a tradewinds generate an overall current, which then swirls and eddies as it hits islands.
Only the Lanai to Molokai (Kalohi) channel seems to have a strong tidal component.
OTOH, if you were to go monitor the currents at the entrance to Pearl Harbor, you would find them relatively predictable and strongly correlated with the rise and fall of the ocean. Just imagine what has to happen as the Pacific Ocean rises and falls 3 or 4', and water flows through the harbor entrance to fill and drain Pearl Harbor.

Yes, that's true. Tidal currents like those at the entrance of Pearl Harbor are pretty much proportional to the total tide level change. The tidal effect of the sun is about 1/4 that of the moon. At new moon, the sun and moon are in line and their effects add. Strangely, when they are opposite of each other, as at full moon, they also add. When they are at right angles to each other, at the quarter moons, the tidal range (difference between high and low tide) is the smallest.Catherine96821:
