Ahi don't behave the same way year-round. Water temperature, bait migration, and current patterns all affect what's working on any given day. Here's what we've learned about matching lures to conditions in Hawaiian waters.
Winter (December - February): Deep and Slow
Water temps drop to 74-76°F. Ahi push deeper and feed less aggressively.
What works:
- Smaller heads (7") with darker skirts
- Slower trolling speeds (6-7 knots)
- Natural color patterns - purples, blues, root beer
This is when finesse matters. The bite windows are shorter, so you need lures that look right even at slower speeds. Light tackle options shine in winter conditions.
Spring (March - May): The Transition
Water warms to 76-78°F. Ahi start moving shallower and feeding more actively as bait comes in.
What works:
- Mid-size heads (7-9")
- Brighter skirts start producing - bleeding patterns, pink/white combos
- Medium trolling speeds (7-8 knots)
Spring is variable. Check water color and temp daily. Green water days, go darker. Blue water, go brighter.
Summer (June - August): Peak Season
Water hits 78-82°F. Ahi are shallow, aggressive, and hungry. This is when the big fish show up.
What works:
- Larger heads (9"+) with aggressive action
- Bright, flashy skirts - lumo, chrome, hot pink
- Faster trolling speeds (8-9 knots)
- Multiple lure spreads - they're competing for food
Summer is when the Ahi Fever sets earn their name. Run them in the short corner and rigger positions.
Fall (September - November): The Second Push
Water temps hold at 77-80°F. Another strong feeding period before winter.
What works:
- Similar to summer but scale back slightly
- 7-9" heads
- Mix of bright and natural patterns
- Watch the moon phase - full moon nights mean slower morning bites
Reading the Conditions
Season is just the starting point. Adjust based on:
Water clarity:
- Clear/blue water → bright, flashy lures
- Green/murky water → darker, natural patterns with more action
Bait presence:
- Lots of flying fish → match the size, go with blues and whites
- Squid around → purples, pinks, lumo at night
Current:
- Strong current → smaller lures, slower speed
- Slack water → bigger lures, more action
The Spread That Covers Everything
If you're not sure what conditions you'll find:
1. Short corner: Bright 9" lure (your confidence bait)
2. Long corner: Natural 7" lure
3. Short rigger: Mid-size with action
4. Long rigger: Different color than your corners
This approach covers your bases while you read the water. Once you see what's working, adjust. For exact positioning and distances, check out our trolling spread guide

If you are just getting into trolling, the fastest way to start catching fish is to run smaller lures. Here is what I tell less experienced fishermen about lure size, leader, speed, and keeping the spread simple.
The exact lures I ran on our last ahi trips and why each one went out: how I match my line count to my crew, pick colors off the week's reports, and read the teeth marks an ahi leaves on a lure head.
