how tall are waves in the middle of the ocean?

Wind waves on Earth range in size from small ripples, to waves over 100 ft (30 m) high, being limited by wind speed, duration, affected area and water depth. When directly generated and affected by local waters, a wind wave system is called a wind sea (or wind waves).

['High tide: when the sea water reaches its greatest height within the tide cycle. They are shown in blue on the tide tables.', 'Low tide: when the sea water reaches its lowest height within the tide cycle. They are shown in red on the tide tables.']

Why don't we find waves in the middle of the sea? ... Waves are generated in the deep ocean by wind. The amplitude of these waves are very small. So they are not seen much.

HEIGHT is the vertical distance of a point to a horizontal surface. ELEVATION is the height of a point above (or below) sea level. SEA LEVEL or, as it is more usually called, mean sea level, is the average height of the surface of the sea.

The average wave height of the highest 10% of all waves will be 22 ft. (7 m). A 5% chance of encountering a single wave higher than 35 ft.

When the highest part, or crest of the wave reaches a particular location, high tide occurs; low tide corresponds to the lowest part of the wave, or its trough. The difference in height between the high tide and the low tide is called the tidal range.

The wave base, which is the depth of influence of a water wave, is about half the wavelength. At depths greater than half the wavelength, the water motion is less than 4% of its value at the water surface and may be neglected.

Its average depth is about 3,688 meters (12,100 ft), and its maximum depth is 10,994 meters (6.831 mi) at the Mariana Trench. Nearly half of the world's marine waters are over 3,000 meters (9,800 ft) deep. The vast expanses of deep ocean (anything below 200 meters or 660 feet) cover about 66% of Earth's surface.

Higher than normal high tides and lower than normal low tides will occur. Mean sea level is generally higher in the early fall months in the Mid Atlantic due to warmer, expanding ocean water and changes in weather patterns.

When a cross sea blows, the water can be difficult to navigate for boaters, as well as swimmers. Part of the reason cross seas are so dangerous is that they generate powerful rip currents, and powerful waves, which can reach nearly 10 feet (3 meters) high, more than enough to swamp a large boat.

Tsunamis are unlike wind-generated waves, which many of us may have observed on a local lake or at a coastal beach, in that they are characterized as shallow-water waves, with long periods and wave lengths. ... A tsunami, on the other hand, can have a wavelength in excess of 100 km and period on the order of one hour.

The amplitude of a wave is the height of a wave as measured from the highest point on the wave (peak or crest) to the lowest point on the wave (trough). Wavelength refers to the length of a wave from one peak to the next. The amplitude or height of a wave is measured from the peak to the trough.

Sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet). The ocean is divided into three zones based on depth and light level.

A wave will begin to break when: distance from shore < wavelength. ... water depth = wavelength/20. water depth = wave height.

There actually are simple... Given the huge area of ocean (140 million square miles) and that ocean waves have wavelengths in the order of 30 feet and upwards, that means in any given square mile there will be around 176 waves, across the ocean, around 25 BILLION waves at any particular time.

The speed of all ocean waves is controlled by gravity, wavelength, and water depth. Most characteristics of ocean waves depend on the relationship between their wavelength and water depth. Wavelength determines the size of the orbits of water molecules within a wave, but water depth determines the shape of the orbits.

The average depth of the ocean is 3,682 meters, or 12,080 feet.
