A wave model requires as initial conditions information describing the state of the sea. An analysis of the sea or ocean can be created through data assimilation, where observations such as buoy or satellite altimeter measurements are combined with a background guess from a previous forecast or climatology to create the best estimate of the ongoing conditions.
High tides generally happen around morning rush hour, between 8 and 10 a.m., and later at night after sunset, between 8 and 10 p.m., according to NOAA's tide predictions. High tide is forecast to ...

The other king tide dates this fall include days surrounding the full moons of Oct. 17 and Nov. 15. According to NOAA, which issues a king tide forecast, high tide flooding events have increased ...
Increased chronic nuisance flooding and king tide flooding is already a problem in the highly vulnerable state of Florida. [212] The US East Coast is also vulnerable. [213] On average, the number of days with tidal flooding in the US increased 2 times in the years 2000–2020, reaching 3–7 days per year. In some areas the increase was much ...
In South Florida, one of the surest signs that fall is here isn’t changing leaves or a chill in the air — it’s saltwater pooling in the street on a sunny day. It’s king tide season again.
Tidal range is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun, by Earth's rotation and by centrifugal force caused by Earth's progression around the Earth-Moon barycenter. Tidal range depends on time and location.
As tides or waves propagate upwards, they move into regions of lower and lower density. If the tide or wave is not dissipating, then its kinetic energy density must be conserved. Since the density is decreasing, the amplitude of the tide or wave increases correspondingly so that energy is conserved.
