You can see from the graph that the tide is still falling, but remember that the current will continue flowing out until after low tide, when it is finally slack low. This means the tide is positive 2 feet, and does not indicate anything at all about the current speed or direction. It is still about noon, and the value is 2.0. The number zero means it’s “slack tide” – there is no current. Note that on the map, the numbers remain positive because direction is indicated by the arrow. Negative numbers mean the current is going out. Positive numbers mean the current is coming in. This means the current is going 4.3 knots (about 5 miles per hour) OUT, shown by the direction of the arrow. On the graph on the right, you can see that it’s about noon, and the value is -4.3. Here, you can see because of the large yellow arrows that the current is going out, or west, into the ocean, out of the Columbia river (aka ebbing). Things can be confusing with tides and currents… here is a real example: This gets back to why DeepZoom is such a great tool – play around with it for a while and you will develop a much better sense of how tides and tidal current interact in the area where you are interested in going. This is a simple example, whereas in real bays, there are narrows, changes in depth, and all sorts of things that affect tidal currents. When it finally stops, that is “slack” tide. Once it becomes high tide, it takes time for the water to actually stop because of all the momentum. Think of it this way: the tide is coming into a bay and the current is moving in through the mouth of the bay (aka flooding). The confusing thing is that when people say “high tide”, they are sometimes refering to when the current is slack, which can be after high tide. Tidal current, however, is the horisontal flow of water from place to place (like a river) that is a result of the tides – measured in knots (1.15 mph). There is a big difference between tides and tidal current – tides are the vertical raising and lowering of water measured in vertical feet. Small yellow squares are tide guages Numbers and arrows are for tidal current. The scroll bar at the bottom allows you to scroll through time to get a visual understanding of the tidal currents in an area. The main thing to not get confused about is that there are two types of guages you can click on: those for tides – the small yellow squares, and those for tidal current – the yellow arrows and/or standalone decimal numbers. For studying tides and tidal current, we highly recommend checking out Deep Zoom. See for a complete list of stations.If you’re planning on fishing out on the salt, it’s essential to have an understanding of the tides and tidal current, especially if you plan on fishing from a kayak. An internet connection is required to get the latest tide graph. Tide Graph has US owned Tide Stations Only. The end results are tested for accuracy and adjustments are made as necessary. The data from these measurements are used to determine the harmonic components which then feed into the mathematical algorithms which predict tides for the future. Unlike simple tide clocks that you can buy in novelty stores, more accurate tide predictions use special data gathered by instruments located at each tide station. The cyclical movement of the Earth's tides are caused by a combination of the gravitational forces of the sun and moon as well as the shape of the costal region. Directly or indirectly, the great flow of our massive ocean bodies of water impact the daily lives of everyone on this planet. Tides have a great influence on the lives of boaters, fishermen, surfers, coastal communities, marine life, and vacationers just to name a few. Save recent locations, find locations using GPS location, and save graphs for later. And now, in version 2.0 you also get an intuitive graph that shows sunrise, sunset, moonrise, moonset, and moon phase at a glance.
Tide Graph uses the harmonic predictions from thousands of US coastal stations and presents them in a fun and interactive graph. 1 million tide predictions sent each month Includes both modern and legacy locations.
