This video depicts the low and high tide event that occurred on 30 May 2009 at Leo Carillo State Beach along the southern California coast. The parts of this video where the low tide scene changes to the high tide scene occur between 1:40 to 1:50 and 3:10 to 3:20.
Science has identified more than 400 factors which contribute to the phenomenon of oceanic tides; the greatest factor is the gravitational pull of the moon. Essentially, tides are the result of a great long-period wave travelling around Earth's oceans as Earth rotates. This wave moves along coastlines as it revolves around amphidromic points (nodes of no vertical wave motion) in oceans, bays, and gulfs. High tide is also known as "flood tide" whereas low tide is also called "ebb tide." Additionally, a tide coming in is said to be "rising" whereas a tide going out is said to be "falling."
Twice per month -- during the full and new moons, when the Earth, moon, and Sun are at syzygy (in line) -- the highest high tides and lowest low tides occur. Tides on these dates with the greatest tidal range are called "spring tides." (The name 'spring tides' has nothing to do with the season of the same name. Spring tides occur throughout the year whenever the conditions described are present.) When the moon is in quadrature (right angle to the Earth and Sun), tides with the least range occur. These tides are called "neap tides." Predictable variation of tides occur on a schedule of 18.6 years, which is the time it takes the moon to complete one cycle of its various motions.
To find the time of high and low tide for any coastal location in the United States, go to this webpage from the National Oceanic and Atmospheric Administration (NOAA):
co-ops.nos.noaa.gov/.
Once on this page ...
1. Click Tide Tables (listed along the left side of the page).
2. On the next page select the year for which you would like to find the tide prediction.
3. Then select the U.S. state where the section of coast in which you're interested is located.
4. On the next page, click on the name of the section of coast closest to, or containing the beach or location for which you would like to view the tide table. (This requires a bit of geographic knowledge. Try Google Earth or Google Maps if you're unsure about your location's situation.)
5. On the next page, you'll see a list of all of the tidal stations or tidal gage locations in your state of interest. Click the word 'Predictions' for the location closest to your place of interest.
To locate the time for low or high tides at Leo Carillo State Beach, I interpolate between the Santa Monica, Municipal Pier and the Mugu Lagoon (ocean pier) tide station data. Leo Carillo State Beach is located roughly between these two, but a little bit closer to Mugu Lagoon. So refer to data from both of these tide charts.
Tidal phenomena -- like everything in the natural world -- are fascinating. Study them!
