Sea surface temperature guide
Cobia (Offshore) sea surface temperature guide.
- Rachycentron canadum
- Pelagic
- Agency-reported threshold data
Offshore cobia is a summer structure fishery — fish hold around platforms, wrecks, and buoys in 72–78°F water. Distinct from the iconic spring inshore Chesapeake and Gulf cobia runs.
SST threshold gauge
The temperature ranges that matter.
The water temperature ranges that determine where cobia (offshore) hold and feed. Hard thresholds (dashed lines) are values outside which fish actively depart or become inactive.
Depth profile & SST reliability
Typical depth
30–300 feet
SST as locator
High — SST is a strong locator
Cobia are surface-oriented at offshore structure. SST is highly predictive of presence.
Current systems & structure
Offshore cobia hold around platforms, wrecks, and buoys. Different fishery from the inshore Chesapeake/Gulf spring run — these are summer fish on offshore structure.
Zone-by-zone calendar
Overlap charts by zone.
For each zone where cobia (offshore) 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.
