San Diego Offshore Fishing in May: Yellowtail & Tuna Adventures

May brings warmer waters and exciting offshore action to San Diego. As spring builds, California yellowtail start arriving on the local reefs and rocky banks. At the same time, baitfish schools begin to concentrate, attracting pelagic species like tuna. Anglers looking for big game should watch the horizon—bluefin and albacore tuna often begin showing up by late May, with yellowfin arriving as summer nears. If you’re chasing tuna, May is the time to plan and book—full-day offshore runs are popular and fill up quickly.

Look for signs of feeding fish on the surface. Warmer spring seas attract large schools of baitfish, which in turn draw predators like tuna, dorado, and yellowtail close to shore. Keep an eye out for diving seabirds or swirling water; when baitfish scatter, it’s time to drop your lines. In May, the water typically warms into the mid-60s°F, luring gamefish within range. A baitball or a tail break often means the bite is on.

What You Might Catch

California Yellowtail: May through October is prime yellowtail season, with peak action typically in June and July. In May, you can expect solid opportunities near local structures and offshore islands.
Tuna (Bluefin, Yellowfin, Albacore): Early tuna like bluefin and albacore start showing by late spring. As the season progresses, schools become more active and accessible to sportfishing boats.

What’s the Weather Like in May?

May in San Diego is perfect for offshore fishing. Daytime temps are mild, typically in the 60s to 70s, with ocean water warming into the mid-60s°F. Mornings often start with a marine layer (known as “May Gray”) that usually clears up by midday. Seas are generally calm, with waves in the 3–5 ft range—ideal for anglers of all experience levels.
