I don't like using the predicted tides from these charts. There are so many factors that play into tides like winds, high pressures, low pressures etc. that I like to use real time data recorders from the area to see exactly what the tides have been doing the past couple days and I use that to tell what the tides will do the following day. Here is the link. Scroll down to the calcasieu, mermentau, vermilion basin section. The last 3 links in that section will be of help to you.
