The best time to dock is during a slack tide. The wind and currents can make a difference. When you prepare to dock your boat, make sure to keep the tides in mind. The sun and moon's gravitational pulls will be at odds with each other. You will see a half-moon, the first and third quarters, when they are aligned this way. Spring tides will happen twice a year during a full and new moon.Ī neap tide will happen when the sun and the moon create a right angle. The tides are stronger throughout this time, and you may notice that there is a greater difference between the water levels during the high and low tides. They occur when the sun and the moon line up with the Earth. Regardless of their name, Spring tides have nothing to do with the season. The current is at its weakest point, and the water appears to be at a standstill. The water will lower as the tide transitions from high to low.Ī slack tide is the short period between the incoming and outgoing tides. Sometimes called an ebb current, the outgoing tide is when the water moves away from the shoreline. More area of the shoreline gets exposed, and docked boats may end up stuck in the sand.Īlso called a rising tide, an incoming tide is when the water is approaching the shoreline as the tide moves from low to high. It is when the water reaches its lowest level. Coastal areas experience two high tides every lunar day.Ī low tide is the opposite of a high tide. It will move to its furthest extent onto the shoreline. Lunar days follow the moon phases, which take 29.5 days to complete.Ī high tide is when the water reaches the highest point. It takes roughly six hours and 12.5 minutes for a tide to move from high to low or vice versa. A lunar day, or tidal day, is 24 hours and 50 minutes long. It is important to know the time regarding tides since it does not coincide with the annual calendar. The tidal range is the difference between the height of high and low tides.Ī current is the speed of the water when it moves from low to high or high to low. To put it simply, the tidal height is the vertical distance that the water rises or falls. You may have heard the term tidal height. They are smaller and may arrive later than predicted if winds are blowing outward. If the wind is blowing inward, then incoming tides usually are higher. The strength and direction of the wind can have an impact on tides by increasing the currents. Tides are affected by the placement of the moon and the sun in relation to the Earth.

It is crucial to know how to dock your boat correctly. In these areas the continents are not pressed closely together, there is not a “constriction” of the oceans, and the tidal ranges are not increased.There are plenty of things to look out for when you are out on the water. In the higher latitudes of the southern hemisphere, in the southern tips of South America, southern Africa, Australia, and Antarctica, tidal ranges are not increased. This “constriction” of the oceans creates the effect of a higher range of tides. In the higher latitudes of the northern hemisphere, the continents of North America, Europe, and Asia are pressed closer together. Increased tidal ranges in these areas are created by the positions and configurations of the continents in the northern hemisphere.
That many of the areas of the world with high ranges of tides are in the areas of Alaska, Canada, and northern Europe has created a misconception that the range of tide increases with increasing latitude (as one moves farther from the equator and closer to the poles). Detailed forecasts are available for high and low tides in all sea ports, but are specific to local conditions. Storm systems at sea and on land also shift large quantities of water around and affect the tides. The shape and geometry of a coastline play a major role, as do the locations of the Sun and Moon. Tidal highs and lows depend on a lot of different factors. The highest tides in the United States can be found near Anchorage, Alaska, with tidal ranges up to 40 feet. The highest tides in the world can be found in Canada at the Bay of Fundy, which separates New Brunswick from Nova Scotia.
