What are spring and neap tides? - NOAA's National Ocean Service
A spring tide—popularly known as a "King Tide"—refers to the 'springing forth' of the tide during new and full moon. A neap tide—seven days after a spring tide—refers to a period of moderate tides when the sun and moon are at right angles to each other.

Explained: What is a neap tide and what is a spring tide?
What is a neap tide? When the sun and moons are at right angles to each other, there is least gravitational pull, meaning the tidal range is at its lowest. The neap tide occurs 7 days after the spring tide. A neap tide is where the sun and …
Tidal range - Wikipedia
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.
Larger tidal range occur during spring tides (spring range), when the gravitation…Wikipedia · Text under CC-BY-SA license- Estimated Reading Time: 5 mins
What are Spring Tides - MyWaterEarth&Sky
Spring tides are a type of tide that occurs when the sun, the moon, and the Earth align in a straight line, exerting their gravitational forces in the same direction. This alignment enhances the gravitational pull on the Earth’s oceans, resulting …
What Causes Tides? | NOAA SciJinks – All About Weather
Feb 14, 2025 · High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to …
Tides and Water Levels - NOAA's National Ocean Service
When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides—both commonly called spring tides.
What Causes Tides? High and Low Tides Explained
Sep 8, 2023 · High and low tides refer to the regular rise and fall of the ocean's waters. High tide occurs when water covers much of the shore after rising to its highest level. Low tide is when the water retreats to its lowest level, moving …
Tides and Water Levels - NOAA's National Ocean Service
The incoming tide along the coast and into the bays and estuaries is called a flood current; the outgoing tide is called an ebb current. The strongest flood and ebb currents usually occur …
Tides - National Oceanic and Atmospheric Administration
Mar 28, 2023 · 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 …
