Hereford Inlet is labeled as Little Hereford on a circa 1700 map by John Thornton, [3] and by its modern name on a map published in 1749 by Lewis Evans. [4] The Hereford Inlet Light is a historic lighthouse located in North Wildwood, on the southwestern shore of Hereford Inlet at the north end of Five Mile Beach.
Hereford Inlet, a break in the barrier islands along the eastern side of Cape May, was first used by whalers in the 17th century.Though the area was frequented, environmental conditions such as shifting sandbars and strong currents created reason for concern and in 1849, a life-saving station was built along the inlet.
Mean high water springs (MHWS) is the averaged highest level that spring tides reach over many years (often the last 19 years). Within this, to ensure anomalous levels are tempered, at least two successive high waters during the highest-tide 24 hours are taken.
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.
A tidal prism is the volume of water in an estuary or inlet between mean high tide and mean low tide, [1] or the volume of water leaving an estuary at ebb tide. [2]The inter-tidal prism volume can be expressed by the relationship: P=H A, where H is the average tidal range and A is the average surface area of the basin. [3]
During these falling and ebbing tides, a riptide can carry a person far offshore. For example, the ebbing tide at Shinnecock Inlet in Southampton, New York, extends more than 300 metres (980 ft) offshore. [2] Because of this, riptides are typically more powerful than rip currents.
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.

A tidal creek or tidal channel is a narrow inlet or estuary that is affected by the ebb and flow of ocean tides. [1] Thus, it has variable salinity and electrical conductivity over the tidal cycle, and flushes salts from inland soils. Tidal creeks are characterized by slow water velocity, resulting in buildup of fine, organic sediment in wetlands.
