Mean ranges near coasts vary from near zero to 11.7 metres (38.4 feet), [4] with the range depending on the volume of water adjacent to the coast, and the geography of the basin the water sits in. Larger bodies of water have higher ranges, and the geography can act as a funnel amplifying or dispersing the tide. [5] The world's largest mean ...
The long and narrow rectangular shape of the Adriatic Sea is the source of an oscillating water motion (called seiche) along the basin's minor axis. [5]The principal oscillation, which has a period of 21 hours and 30 minutes and an amplitude around 0.5 meters at the axis' extremities, supplements the natural tidal cycle, so that the Adriatic Sea has much more extreme tidal events than the rest ...
Because of tidal resonance in the funnel-shaped bay, the tides that flow through the channel are very powerful. In one half-day tidal cycle, about 100 billion tonnes (110 billion short tons) of water flow in and out of the bay, which is twice as much as the combined total flow of all the rivers of the world over the same period.

Highest astronomical tide (HAT) – The highest tide which can be predicted to occur. Note that meteorological conditions may add extra height to the HAT. Mean high water springs (MHWS) – The average of the two high tides on the days of spring tides. Mean high water neaps (MHWN) – The average of the two high tides on the days of neap tides.
King tides are the highest tides. They are naturally occurring, predictable events. Tides are the movement of water across Earth's surface caused by the combined effects of the gravitational forces exerted by the Moon, Sun, and the rotation of Earth which manifest in the local rise and fall of sea levels. Tides are driven by the relative ...
The deeper tides will start Friday and continue through Monday, and can run 6 inches to a foot higher than a typical high tide in the summer. The king tides will return later in the fall, Oct. 27 ...
In coastal areas, because the ocean tide is quite out of step with the Earth tide, at high ocean tide there is an excess of water above what would be the gravitational equilibrium level, and therefore the adjacent ground falls in response to the resulting differences in weight. At low tide there is a deficit of water and the ground rises.
In Manatee County, the highest chance of breathing irritation was forecast for the north end of Anna Maria Island. Red tide respiratory risk is most likely when winds are blowing on or along the ...
