July 2025 — San Diego: Pacific bluefin tuna peaks, full offshore season. July is a summer month with water in the 68-72°F range — bluefin and yellowfin offshore; yellowtail at the islands; dorado arriving. Here’s the full breakdown of what’s biting, where to fish, and the most productive tactics.
What’s Biting — July 2025
Primary targets this month: Bluefin Tuna, Yellowfin Tuna, Yellowtail, Dorado.
Bluefin Tuna
Bluefin tuna on the offshore 30-100 mile zone — the famous southern California bluefin fishery has been epic in recent years, 100-300+ lb fish on jigs and surface poppers. Trolled spreader bars, ballyhoo, large stickbaits; jigging with knife jigs in 200-400 feet; chunking when anchored over bait. HMS permit required.
Yellowfin Tuna
Yellowfin tuna on the offshore 60-180 mile grounds in summer/fall (long-range trips), the U.S./Mexican border banks, and El Toro Bank. Chunking (cut sardine, butterfish) at anchor, live bait drifting, or trolled feathers and cedar plugs. Heavy stand-up tackle (50-80 lb class) for the bigger grades.
Yellowtail
Yellowtail on the Coronado Islands, the 9 Mile Bank, the 14 Mile Bank, and the kelp lines off La Jolla and Point Loma — May through October peak. Live mackerel, sardines, or anchovies on 4/0-6/0 circle hooks. Slow-trolled or fly-lined. Heavy enough tackle (40-50 lb) to keep them out of the kelp.
Dorado
Dorado (mahi) on the offshore in late summer/early fall, the kelp paddies, and floating debris. Find a kelp paddy or any floating debris; bonus fish around the long-range tuna boats. Live or cut bait, small skirted lures, and even fly tackle.
Water Conditions & Patterns
Water temperatures are running 68-72°F. Bluefin and yellowfin offshore; yellowtail at the islands; dorado arriving. San Diego tides are 4-6 feet — significant for kelp and bay fishing. Bay halibut bite best on the moving tide. Kelp fishing for calicos peaks on slow current as kelp lays back. Offshore tuna driven by water temperature and current rather than tide.
Check the NOAA marine forecast and tide charts before launching. Wind direction often matters more than wind speed for inshore fishing — clean water beats churned water nine times out of ten.
Tactics & Tackle for This Month
- Water temperature is everything. Yellowtail like 64°F+, white seabass like 60-65°F squid spawns, bluefin tuna 68-72°F.
- Live bait priority. Bait quality determines success — buy active anchovies and sardines from the bait barge, use them quickly.
- Long-range season. Multi-day trips on big boats access the best offshore fishing.
July Outlook
Summer pattern locked in — dawn/dusk inshore, deep offshore, manage heat.
Regulations Reminder
Tuna: NOAA HMS permit required. Strict size and bag limits — verify current NOAA rules. Yellowtail (CA): 24″ fork length minimum, 10 per day. Always verify current state regulations before each trip — slots, bag limits, and seasons change.
