Really never seen them quit totally . Sure helps to have livescope . Find the fish hold a bait on their nose . Seems like here they tend to move out to first drop and if severe cold front hug the bottom . Good job on figuring them out . The old saying , winds out of the eat they bite the least , out of the south falls in their mouth , west wind bite is the best , winds from the north don't go forth ! This no longer applies if you know where to look with good electronics and stand the weather conditions !
