Official U.S. high and low tide predictions. Show when, where, and how often high tide flooding may occur at specific locations. Nowcast and forecast (out to 48-72 hours) model information on water levels, currents, wind, salinity, and water temperature.

Earth tides, which raise and lower the bottom of the ocean, and the tide's own gravitational self attraction are both significant and further complicate the ocean's response to tidal forces.

2024年6月16日 · Tides are very long-period waves that move through the ocean in response to the forces exerted by the moon and sun. Tides originate in the ocean and progress toward the coastlines where they appear as the regular rise and fall of the sea surface.

2023年3月28日 · Tides are another type of wave motion – a change in the ocean water level that typically reaches a high and low twice a day, about six hours apart (called a semi-diurnal tide). The change from low to high tide is called the "flood tide" or “flow”.

Tides & Currents Coastal Ocean Reanalysis. CO-OPS provides the national infrastructure, science, and technical expertise to monitor, assess, and distribute tide, current, water level, and other coastal oceanographic products and services that support NOAA's mission of environmental stewardship and environmental assessment and prediction. CO-OPS provides operationally sound observations and ...

NOAA's annual tide and tidal current tables include predictions for more than 10,000 international locations. You can get tide predictions and tidal current predictions online for U.S. coastal stations and some islands in the Pacific and Caribbean, for a time period of up to two years.

2016年6月20日 · The word "tides" is used to define the rise and fall in sea level resulting from the gravitational attraction of the moon and the sun. The result of this pull is a bulge in the ocean water almost in line with the position of the moon; one bulge toward the moon and one on the opposite side of the earth, away from the moon.

Want to know the high and low tides for locations around the United States? Visit the Center for Operational Oceanographic Products and Services Web site. You'll find tidal predictions for more than 3,000 water-level stations around the United States.

Caused by the gravitational pull of the moon and the sun, tides are very long-period waves that move through the ocean and progress toward the coastlines where they appear as the regular rise and fall of the sea surface.
