What time is high tide at High Island, ICWW today?

The next high tide at High Island, ICWW is tomorrow at 12:36 am local time, reaching 1.75 ft above MLLW. The next low tide is at 3:31 pm (0.29 ft).

How many tides does High Island, ICWW get per day?

High Island, ICWW has diurnal tides, which means a single high and a single low each day. Times shift roughly 50 minutes later each day as the moon advances, which is why a printable weekly or monthly table is more useful than a single day's times.

When is the lowest tide this week at High Island, ICWW?

The lowest tide at High Island, ICWW in the next seven days is 0.29 ft at 3:31 pm on 2026-10-13. The highest is 1.78 ft at 5:18 am on 2026-10-15.

Is this a spring tide or a neap tide at High Island, ICWW?

Tides here are currently between spring and neap. The moon is waxing crescent (8% illuminated). Spring tides, the biggest range between high and low, follow the new and full moon, when the sun and moon pull in line. Neap tides, the smallest range, follow the quarter moons.

What time is the lowest tide today at High Island, ICWW?

The lowest tide today at High Island, ICWW is at 3:31 pm at 0.29 ft above MLLW. The lowest predicted tide over the next month at High Island, ICWW is -0.03 ft.

What is the rule of twelfths for tides?

The rule of twelfths estimates how much water moves in each hour of a roughly six-hour tide: 1/12 of the range in the first hour, then 2/12, 3/12, 3/12, 2/12 and 1/12. Water moves fastest in the middle two hours and barely moves near high and low slack.

What is the best tide for fishing at High Island, ICWW?

Most inshore anglers prefer moving water rather than slack tide, so the two hours either side of a high or low, when the rule of twelfths says flow is fastest, tend to fish best. Using today's predictions, the strongest movement is between consecutive tide changes. Local conditions, wind and season matter as much as the tide itself.

Is it better to go to the beach at high or low tide?

Low tide exposes the most sand and the widest walking beach, and is best for tidepooling and shelling. High tide suits swimming and launching boats, though it leaves less dry beach. At High Island, ICWW the difference between the two is about several ft of water height.

What is the rule of 6 for tides?

"Rule of 6" is another name for the rule of twelfths above. It is the idea that a tide takes about six hours to run, and that the water moves by a different fraction of its range in each of those six hours. Some people also use it as shorthand for the roughly six-hour gap between a high and the next low, which at High Island, ICWW averages about 24.0 hours today.

How accurate are these tide predictions?

The tide times on this page are NOAA's astronomical predictions for station 8770808, typically within about 10 minutes on timing and half a foot on height. They account for the sun and moon but not the weather. A strong onshore wind, a storm surge or unusually high or low barometric pressure can push the real water level well above or below the prediction. Never use them for navigation or life-safety decisions. NOAA's own page for this station carries the official record.

What datum are these heights measured from?

All heights are feet above mean lower low water (MLLW), the standard NOAA tidal datum for US coastal predictions, the average of the lower of the two daily low tides. A reading of 0.0 ft means water at that reference level, and a negative reading means below it.

How warm is the water at High Island, ICWW?

The water temperature at High Island, ICWW is 84 °F (29.0 °C), measured 2:36 pm by NOAA CO-OPS. It has risen 1.4 °F in the last 24 hours.
