Step 1:
Know where you are going
For me choosing a area to fish is the hardest decisions to make. The options in south Louisiana are endless between the different saltwater and freshwater fishing areas that we have.
If you live in Louisiana become a member at
BCKFC.org and use their member maps to select from the hundreds of tried and true launch locations.
If not use your local club or Google earth to find likely launch spots.
step 2:
Check the weather
You should probably do this before and after choosing your launch location but once is enough for me. To be Honest most of the time this is a step I skip and I end up launching in Twenty mph winds or caught racing a thunderstorm back to the launch.
Watch the news for the upcoming forecast or use your favorite online weather forecasting site. I like
http://www.weather.com/weather/hourbyhour/graph/USLA0194 and their hourly feature just dont trust their wind forecast.
http://tidesonline.nos.noaa.gov/geographic.html This site gives you real time data including water levels, water temperature, wind speed, as well as predicted tide charts.
http://waterwatch.usgs.gov/?m=real&r=la some more tide info has some different stations
When on the water the
weatherbug app is great for keeping track of the weather.
Step 2:
Do some virtual scouting
Read some recent reports from the area you have chosen make note of any GPS coordinates, names of waterways ,and any other geographical info that was referenced.

Use Google Earth and explore the area you intend on fishing. Make note of areas of interest
this is a good summary of how its done.
