WATER TEMPERATURE GRAND ISLE

TODAY, SATURDAY, JULY 21, 2018

The effects of Water Temperature

Fish are cold blooded, which means their metabolism is strongly influenced by the temperature of their surrounding environment. Fish want to stay comfortable. Consequently, even a small change or break will cause fish to move from one location to another.

In general, this behavior varies for each species and place, so we can not specify an ideal water temperature, however as a general rule we will try to avoid the temperatures abnormally cold in summer and too warm in winter. Remember, look for the comfort zones and you will find the fish.

Current Temperature air / water

JULY 21, 2018, 10:46 am

Water temperature plays an important role in the behavior of fish. When the water is cold, fish are lethargic and inactive, and the same happens if the water is too hot.

At this moment the current water temperature in Grand Isle is -. The average water temperature in Grand Isle today is -.

SWELL GRAND ISLE

TODAY, SATURDAY, JULY 21, 2018

Significant wave height

It is normal for waves to vary in height from one to the next. To give you an idea of the range of waves to expect at a given time, we consider the significant wave height as the average height of the highest third of the waves in the open sea.

The significant wave height provides an estimation of wave heights recorded by a trained observer from a fixed point at sea because we tend to pay more attention to the larger waves.

Current wave conditions

JULY 21, 2018, 10:46 am

Wave direction - (-°)

Significant height -

Wave period -

Most frequent waves

The most frequent wave height will be about half the height of the significant wave.

Significant height

About 14% of waves will be higher than the significant wave height (about 1 in every 7 waves).

Maximum waves

It is normal to expect a wave of twice the height of the significant wave about 3 times in 24 hours.

This means at this moment you need to be prepared for a wave of - before heading out on the water.

The waves you will find on the shore can be slightly affected by the orientation of the coastline and the seabed of the beaches, although in most cases they are usually equivalent.

TIDAL COEFFICIENT GRAND ISLE

TODAY, SATURDAY, JULY 21, 2018

MORNING

AFTERNOON

Tidal coefficient

JULY 21, 2018

The tidal coefficient today is 49, a low value, which means that the range (difference between high tide and low tide) will be lower than on other occasions and the currents will also be small. At noon the tidal coefficient increases to 50. The day ends with a tidal coefficient of 51.

The heights today are 1.0 ft and 0.1 ft referenced to Mean Lower Low Water (MLLW).

We can compare these levels with the maximum high tide recorded in the tide tables for Grand Isle which is of 1.6 ft and a minimum height of -0.7 ft.

2018 tidal coefficients

The following graph shows the progression of the tidal coefficient in the month of July of 2018.These values give us a rough idea of the tidal amplitude in Grand Isle, forecast in July.

Large coefficients indicate important high and low tides; major currents and movements usually take place on the sea bed. But bear in mind that this tidal amplitude may be greatly affected by the weather and you should also consult the weather forecast in Grand Isle and the wind and wave forecast in Grand Isle before you go fishing.

TIDE TABLE GRAND ISLE

JULY, 2018

All the times are generated in local time in Louisiana and the daylight saving time change has also been borne in mind for your convenience, so you don't need to add or subtract anything.

The heights are expressed in feet referenced to Mean Lower Low Water (MLLW). It is the average of the lower low water height of each tidal day observed over the official time segment over which tide observations are taken and reduced to obtain mean value.

You can change the time format and the default unit for height in the

SOLUNAR ACTIVITY GRAND ISLE

TODAY, SATURDAY, JULY 21, 2018

SOLUNAR ACTIVITY: LOW

According to the solunar theory, today is a bad day for fishing, the fish activity forecast is low, however, this is just a chance so we encourage you to take your rod and try it during solunar periods.

The best times of day for fishing are:

MAJOR PERIODS

AVERAGE ACTIVITY

from 8:18 am to 10:18 am

Opposing lunar transit (moon down)

from 8:37 pm to 10:37 pm

The solunar periods indicate the best times of day for fishing in Grand Isle. The major periods correspond to the lunar transit (passage of the moon over the meridian) and the opposing lunar transit and last approximately 2 hours. The minor periods begin with the rising and setting of the moon and its duration is approximately 1 hour.

When the solunar period coincides with sunrise or sunset, we can expect more activity than initially planned. These peak periods are reflected in green. We additionally point out in the chart the periods of greatest activity during the year with a big blue fish on the period bar + info
