The Florida Middle Grounds are a rocky live-bottom plateau in the Eastern Gulf — a year-round bottom fishery for grouper and snapper, with summer Loop Current eddies bringing pelagics within range.
Climatologically typical sea surface temperature ranges based on NOAA CoastWatch SST climatologies. Year-to-year variation is real — verify with current SST imagery before each trip.
| Month | Typical SST | Dominant current | Notes |
|---|---|---|---|
| January | 60–68°F | Continental shelf with Loop Current eddy influence | Cool winter; gag and red snapper out of season but red grouper. |
| February | 60–66°F | Same | Same. |
| March | 62–70°F | Same | Spring fishing building. |
| April | 70–76°F | Same | Multi-species offshore fishing. |
| Maynow | 74–80°F | Same | Strong offshore fishery. |
| June | 80–84°F | Same with Loop Current eddies | Peak summer. |
| July | 82–86°F | Same with Loop Current eddies | Peak summer. |
| August | 82–86°F | Same with Loop Current eddies | Same. |
| September | 80–84°F | Cooling shelf with eddies | Strong fall fishery. |
| October | 74–80°F | Cooling shelf | Continuing. |
| November | 68–76°F | Cooling shelf | Bottom-fishing season. |
| December | 62–70°F | Continental shelf cold | Winter pattern. |
For each target species, the cells show whether typical monthly SST in Florida Middle Grounds & Tampa Offshore falls in that species' preferred or optimal range. Best all-around months: November, April, May, October.

For each species in their preferred SST range this month, the gauge shows the threshold band — verify against current SST imagery before deciding on the run.
Persistent SST features that concentrate baitfish and predators. Use SST imagery to find the break, then fish the warm side.
The Loop Current is the Gulf of Mexico's equivalent of the Gulf Stream — warm Caribbean water that flows north into the Gulf and loops back through the Florida Straits. Its position varies year to year. The current's edge and the eddies it sheds are the primary blue-water structure in the Gulf.
Wind, swell, and tide-stage forecasts for the offshore zone. Pair with SST imagery for trip planning.
Bield: Fish overlays NOAA CoastWatch SST imagery onto your navigation view, highlights temperature breaks within your target species' threshold band, and alerts you when your home zone hits the optimal window.
