Questions people ask about Grand Isle
Answered from the same readings as the rest of this page. Where we have no basis for an answer, there is no entry — spot-by-spot local knowledge is not something we can claim for Grand Isle.
- Is it worth fishing Grand Isle today?
- 5 out of 10 — picky. Work for it. The strongest stretch is 12:33 AM–2:33 AM. That number is worked out fresh each morning from the solunar windows, the pressure trend, the water level and the water temperature.
- What time should you fish Grand Isle?
- Today's major windows run 12:33 AM–2:33 AM and 12:58 PM–2:58 PM, with minor windows at 6:50 AM–7:50 AM and 7:57 PM–8:57 PM. Sunrise is 6:27 AM and sunset 7:41 PM. A major landing on first or last light is the stretch worth setting an alarm for.
- What is the water temperature at Grand Isle?
- 88.5°F, read at 3:30 AM from NOAA CO-OPS station 8761724. That is 0.9 degrees cooler than 24 hours ago.
- What is the water level at Grand Isle right now?
- 0.65 ft above MLLW, read at 3:30 AM from NOAA CO-OPS station 8761724. Over 24 hours it is down 0.13 ft.
- Can you eat the fish you catch in Grand Isle?
- That is a health question and it belongs with the state, not with us. LA publishes fish consumption advisories through its health or environmental agency, and those are the ones that count. We give no eating advice.
- What size fish can you keep in LA?
- It depends on the species, and several have slot limits rather than a simple minimum. Open to harvest today: spotted seatrout (speckled trout), red drum (redfish), black drum, southern flounder. Seasons here change mid-year by agency order, so the status is re-checked every morning.
Where these numbers come from
- Solunar computed 3:36 AM
- NOAA KGAO Galliano, South Lafourche Airport 2:55 AM
- NOAA LIX gridded forecast 2:02 AM
- NOAA CO-OPS 8761724 Grand Isle 3:30 AM
The CO-OPS station sits on the island itself, and the USGS gauge in Barataria Pass adds a second water-temperature reading on the back side.
No one types these in by hand. If a source goes quiet, the page says so instead of showing you yesterday.
