When is the best month to catch bluefin tuna in California?
While bluefin tuna can pop up at any time, June through September is usually when the prime bluefin action happens off the Southern California coast. During these months, you can expect to encounter anything from smaller schoolies to whoppers that are 100, 200 or even 300 pounds plus.

Why Summer is Tuna Time
As the ocean warms up and bait concentrations get more abundant, big schools of bluefin start moving through the waters off San Diego and Baja California. This creates some of the best offshore fishing action you can find anywhere.
A lot of experienced captains agree that July and August often have the most consistent fishing, but June and September can be equally productive depending on what's happening with the water and the bait.
If you're after the ultimate bluefin experience, this is when the top bluefin fishing charters in the area start running their overnight and multi-day trips to make the most of the action.
Overnight Trips: The Secret to Catching More Bluefin
Bluefin tuna are highly migratory and can travel a long way offshore. That's why a lot of serious anglers look for the best overnight deep sea fishing charters San Diego has to offer.
Overnight trips have a number of advantages:
- More time to fish the spots that have the best action
- Access to the offshore banks and bluefin zones that really produce
- Opportunities to fish the prime morning and evening feeding periods
- A better chance of landing a giant bluefin
If catching a monster bluefin is your goal, an overnight or multi-day trip gives you the best shot at success.
Just How Big Do Bluefin Get in California?

Professional captains spend all their time tracking:
- Water temps

Smaller passenger loads usually mean more fishing time and more personalized attention from the crew.
