Today at East Point, Grand Isle, LA
Today's predicted high and low waters, sunrise and sunset for East Point, Grand Isle, LA load here from NOAA. Without JavaScript they cannot be shown: NOAA's own table for station 8761724 is at tidesandcurrents.noaa.gov. Everything else on this page is measured and does not change from day to day.
What the tide does at East Point, Grand Isle, LA
Across the 764 high and low waters NOAA predicts here for 2027, high water averages 1.09 ft above MLLW and low water -0.02 ft — a mean range of 1.11 ft. Taking each day's higher high and lower low, which is the swing someone standing on the shore actually sees, the average is 1.18 ft.
On 7% of days in 2027 there are two high waters and on the remaining 323 days only one. Where there are two, they differ in height by 0.14 ft on average. Successive high waters are 22h 57m apart on average.
The largest daily swing of 2027 is 2.27 ft on 3 July 2027 and the smallest is 0.1 ft on 20 August 2027 , a factor of 22.7 between the biggest spring tide and the smallest neap.

What MLLW means here
Every height on this page is feet above MLLW — mean lower low water, the chart datum NOAA publishes tide predictions against. It is the average of the lower of each day's low waters, taken over a 19-year period, so zero here is neither the sea bed nor the average sea level: it is a level the water drops below regularly. At East Point, Grand Isle, LA, 202 of the 382 low waters predicted for 2027 — 53% of them — fall below zero, the lowest being -1.07 ft on 20 January 2027.
Practically: a chart showing 6 ft of water here means about 6 ft at a mean lower low water and about 7.2 ft at a mean higher high. Add the predicted height for the moment you care about to the charted depth.
Where these predictions come from
This is a reference station: NOAA computes its predictions directly, from a harmonic analysis of water levels measured at this location, rather than by offsetting another station's table.
12 nearby stations take their predictions from this one by applying a time and height offset: Empire Jetty, Bastian Island, Quatre Bayous Pass, Independence Island, Barataria Pass, Manilla, Pelican Islands, Timbalier Bay, Timbalier Island, Timbalier Bay, and 4 more.
Daylight at this latitude
East Point, Grand Isle, LA sits at 29.2633° N. The longest day of 2027 here is 14h 01m of daylight on 21 June 2027; the shortest is 10h 16m on 21 December 2027 — a difference of 3h 45m.
Day lengths are computed with NOAA's published solar algorithm from the station's latitude and longitude. Clock times for sunrise and sunset are deliberately not printed here: they depend on the station's UTC offset, and this site takes that offset from NOAA's own answers rather than from a timezone table — so it is the live panel above, which has them, that shows the times.
