Tides in Grand Isle
Today's high and low tides
- ▲ High tide 12:09 am 1.6 ft · coef. 110
- ▼ Low tide 11:10 am -0.1 ft
↑ Rising The tide is rising. 8 h 6 min to high tide at 1:04 am.
Tide coefficient 110 for the 12:09 am high tide. Big spring tides. The water rises and falls 1.7 ft between the highest high and the lowest low: a large range for this place. 70 is an average tide here; 90 and above means spring tides; below 45, neap tides. What is the tide coefficient?
2026 extremes: the highest tide of the year is on October 30 (1.7 ft) and the lowest, on January 30 (-1.0 ft).
Diurnal: one high and one low tide a day most days.
Heights above mean lower low water (MLLW), the zero of US nautical charts. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. MLLW
Tide coefficient and range in October
The biggest tides of the month come from October 29 to 30 (coefficient 118, 1.8 ft range). The smallest, on October 22 (coefficient 22, 0.3 ft).

Where this tide comes from
Tides from the Bayou Rigaud station (NOAA), 2.4 mi from Grand Isle. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the East Point reference station with the official corrections.

The sea at Grand Isle
Sea stateSea state: slight
The waves you may find
- Most commonMost common0.9 ft
- Significant1.8 ft
- Highest expectedHighest3.9 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.9 ft. Before heading out, expect waves of up to 3.9 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Cross-shore wind. The coast faces south and the wind blows along the shore: drift and current run parallel to the beach.

Waves build over the next few days. The biggest waves arrive on Tuesday 3: 3.9 ft with a period of 5 s, from the east-southeast (slight).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water warms over the next few days: about 76.0 °F by Tuesday 3.

Surf in Grand Isle today
Surf today
Poor- 1.0–1.5 ft surf at the shore, small: good for learning or a longboard
- 1.1 ft swell at 5 s from the southeast, short: weak, messy waves
- Light offshore wind (10 mph): it holds up and grooms the waves
- Falling tide (low tide at 11:10 am)
- Light: First light 6:46 am · sunrise 7:10 am · sunset 6:17 pm · last light 6:41 pm
- Tide: high 12:09 am (1.6 ft) and low 11:10 am (-0.1 ft). Every break has its own tide: some work at low tide and others at high tide. The tide doesn’t change the score here.
- Water at 73.2 °F: a rash guard or a neoprene top.
- Energy: 6 kJ · Low power
Today’s surf at a glance
The best window, 7:00 am to 11:00 am, has light offshore wind, though with small waves and a short-period swell.
An estimate for this stretch of coast, not for a specific break: every beach or reef works its own way (its tide, bottom and angle). Check it when you get there.
Follow the flags and the lifeguards, and don’t paddle out if the surf is above your level: this score is a guide, not a substitute for what you see when you get there.

Your diving day at a glance
The best window, 10:30 am to 11:30 am, combines slack water at low tide, little swell, light wind, weak current and the sun high.
Slack water comes from the tide: in inlets, channels and between islands the water can keep running for an hour or two after. Ask the local dive shop.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

Moon phase and position
Today the moon is 226,426 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 1:37–3:37 am Major · the moon passes overhead · high activity
- 2:09–4:09 pm Major · the moon passes underfoot · high activity
- 9:30–10:30 am Minor · moonset · medium activity
- 7:46–8:46 pm Minor · moonrise · medium activity
According to solunar theory, fish feed more when the moon passes overhead or underfoot (major periods, about 2 h) and when it rises or sets (minor periods, 1 h). It works best around new and full moon.

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 0.9 mi): cast far from the beach and fish the high tide, when there is more water close in.
- Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
- Diving. Shallow: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
