A low tide is caused when the ocean is at its lowest point of the beach. On the beach, we notice that the sea is far away and leaves a large patch of sand once covered at high tide exposed. Low tides are caused when the earth is a right angles to the moon.

Because the Earth rotates through two tidal “bulges†every lunar day, coastal areas experience two high and two low tides every 24 hours and 50 minutes. High tides occur 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high.

Tides in San Diego, CA for Today & TomorrowNext high tide is 12:02 pm. Next low tide is 7:22 pm. Sunset today is 6:05 PM. Sun rise tomorrow is 7:00 AM.
You can tell if the tide is coming in or out by reading a local tide table since they list the predicted times that the tide will be highest and lowest. In the time that the tide shifts from its lowest point to its highest point, the tide comes in.

Water temperature in Siesta Key today is 83.8°F.The swimming season in Siesta Key lasts from March to December.
The beach at North Shell Road faces Lido Key and Big Pass. The sandbars there produce sand dollars, augers, lightning whelk, spiny jewel box, and olives at low tide. Watch for the currents though.
As the tides rise and fall, the salinity (salt concentration) constantly changes. Animals living in the intertidal zone must be able to tolerate wide salinity variations. If sufficient nutrients are available, intertidal animals reproduce rapidly, so they constantly compete for space, light, and food.
At low tide, water moves away from you and towards the “bulge†created by the gravitational effect of the moon and/or the sun. Conversely, when the “bulge†is at your location, water flows towards you, giving you a high tide.
They are caused by the gravitational forces exerted on the earth by the moon, and to a lesser extent, the sun. When the highest point in the wave, or the crest, reaches a coast, the coast experiences a high tide. When the lowest point, or the trough, reaches a coast, the coast experiences a low tide.
The side of the Earth closest to the Moon experiences the Moon's pull the strongest, and this causes the seas to rise, creating high tides. On the side facing away from the Moon, the rotational force of the Earth is stronger than the Moon's gravitational pull.
On the “near†side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean's waters toward it, creating one bulge. On the far side of the Earth, inertia dominates, creating a second bulge. In this way the combination of gravity and inertia create two bulges of water.
