Puerto Vallarta’s sportfishing runs June–December, peaking October–December for marlin, dorado (mahi-mahi) and yellowfin tuna. June–October is strong for mahi-mahi and chances for marlin/sailfish; mid‑September–December sees the best big-game action, with El Morro, Las Marietas and El Banco as top offshore spots. Trips range from bay and inshore outings for beginners to full-day offshore charters and luxury yachts, and year‑round tournaments culminate in the November International Marlin & Sailfish Tournament.
