Grand Isle surf conditions?

[rondajoe]

Hey guys this is my first post here or anywhere. My 2 sons and I plan to wade fish on GI Thurs and Fri. The weather reports say that the winds have been and will be up to 15mph from the South until Wed. around 4pm. My question - Is that enough wind to mess the surf fishing up and how long does it take to become productive again if it does? Thank you for any help.
