Sea surface temperature guide

Greater Amberjack sea surface temperature guide.

Agency-reported threshold data

Greater amberjack are the iconic deep-structure fight fish — wrecks, rigs, and ledges from the Carolinas through the Gulf. SST is less predictive for AJ than for pelagics; bottom structure is the key locator.

SST threshold gauge

The temperature ranges that matter.

The water temperature ranges that determine where greater amberjack hold and feed. Hard thresholds (dashed lines) are values outside which fish actively depart or become inactive.

Depth profile & SST reliability

Typical depth

60–500 feet

SST as locator

Moderate — SST is a partial signal

Amberjack hold over deep structure and respond to current edges. Surface SST is a weaker signal than for pelagics.

Current systems & structure

Temperature breaks

Amberjack key on bait pushed onto wrecks and rigs by current. Spring and fall current breaks concentrate fish.

Best zones now

Where greater amberjack are in range — June.

Zones where typical June SST falls in greater amberjack's preferred range.

Zone-by-zone calendar

Overlap charts by zone.

For each zone where greater amberjack are present, the chart overlays the zone's typical monthly SST range with the species' preferred and optimal ranges. Months where the bands overlap are when fish are in range.

Conservation & regulations

GMFMC / SAFMC / NOAA

Overfished (Gulf) — under recovery plan. Closed seasons during spawning periods. Tight bag and size limits. Verify current rule before harvest.

Stock assessment source →

Drop big jigs and live blue runners to wrecks, rigs, and reefs. Amberjack are aggressive — they'll hit anything that looks alive. Target current-facing edges of structure.
