Every area fishes differently especially for the elusive jew. For my area, the best time on my favorite spot is 2hr before low until low especially if it coincides with a low light period. The other spot I have is best 1hr either side of high tide. Remember, fish are creatures of habit too, so once you crack the code. Try and replicate those conditions and you will be more successful.
Hope that helps!
