Nuevo Vallarta fishing report October 2018. The abundance of sailfish , Marlin, and mahi – mahi have kept us busy fishing here in Nuevo Vallarta for the larger hot marlin this month. The offshore action right now for October is really and getting better. The most consistent bite has been around the Corbetena or Rock were there has been nice tuna as well. These trips that we’re doing now offshore are 8 to 10 hours and I’ve had some really great success on all the pelagic fish that were fishing for here in Nuevo Vallarta Mexico. The black and blue marlin have been hitting the live bait very well and also some of our black Bart larger lures. The best Vallarta had one on the other day that was almost 700 lb.
