What was biting
Striped marlin
Striped marlin and sailfish were the most common billfish in our crews’ photos all month. We follow Cabo’s local rule of one billfish per boat per day and encourage catch and release.
Yellowfin tuna
Yellowfin tuna came in good numbers, with bigger fish in late August. One group needed three people to hold up their tuna for the photo.
Dorado (mahi-mahi)
Dorado were steady close to shore and offshore, including fish caught by young anglers on their first trip.
Wahoo
Wahoo hit on the troll in late August, a bonus fish that is fast, strong and great on the grill.
Also seen: Pacific sailfish.

Planning a trip for this time of year?
Late summer is when Cabo has the most variety, and also the hottest days. Go out early, bring sun protection, and choose a boat with shade or air-conditioning if you have kids along.

How we put this report together
This report is based on the photos our captains and crews sent from their trips during these dates. We don’t publish catch numbers we can’t verify. Water temperatures come from NOAA and moon phases are calculated for Cabo San Lucas time.
