Small tidal stream inaccuracies can develop when advancing beyond HW Dover +6. Because of this we only enable today's tidal stream chartlets to advance 24 hours. Sorry, future tides are not currently available for this harbour. Please check Admiralty EasyTide.
The above image represents the current tidal streams offshore of this haven. Streams attaining three knots and above are highlighted by red arrows . All times are in local time with red text indicating springs, blue indicating neaps and gray between tidal events. Click [+] to advance the estimate by an hour and click [-] to step back.

Arrows represent the direction of tidal streams with lighter or shorter arrows indicating weaker streams. Stronger streams are indicated by heavier or longer arrows, and as mentioned above, red arrows flagging rates of 3 knots and above. Numerals represent [mean neap, mean spring] rates in tenths of a knot. For example the numbers 12,23 would indicate a mean neap of 1.2 knots and a mean spring of 2.3 knots.

Spring and neap tides are caused by the gravitational attraction of the moon and to a lesser extent the sun. The complex mix of gravitational forces raise bulges of water on both sides of the Earth. These vary in size depending upon the moon's position as it revolves around the Earth each month.
When the moon's orbit places both the moon and the sun's gravitational forces in line, during New Moon and Full Moon , the water level rises higher, falls lower and the tidal runs are faster than usual. These are called spring tides, shown in red. When the moon is in the First Quarter or Last Quarter , out of phase with the sun, lower tides result and lesser tidal runs will be experienced. These are called neap tides, shown in blue.
The maximum spring tide typically lags a day behind the date of New and Full Moon in the British Isles. This is caused by the water masses inertia and friction plus the physics of 'cause and effect' where the largest impact occurs after the force has been imparted.
This tool can be used to estimate future costal tidal streams for this area. All that is required are two simple steps:
Step 1: What is the Dover High Water for the target date?
Use a current Dover Tide Table to find Dover High Water for the target date. The National Oceanography Centre offers online tidal predictions for up to 28 days from today. Click here to open their tide table for Dover
Step 2: Input the target date's Dover High Water
Taking a mean tidal offset from Dover's tide, we expect your targetted date's associated local tide at to be:
High waters: Low waters:
Data based on an average tide is only accurate to within one hour, if you more precise times are required use the ISA tidal predictions, with offset -01:00.
Welcome to the 'find routes' tool. Use this tool to discover all the coastal descriptions, short cuts, and tidal strategies we offer for a particular passage between our listed destinations; more information.
All pages provide our menu bar, to navigate to and browse through listed 'Routes', plus our site wide text search capability. The text search capability may be narrowed to individually target 'Experience', 'Routes' or 'Havens' by selecting the tabs beneath the search box. But text searches are not optimal when it comes to finding Routes pertaining to a particular passage unless you know what you are looking for. This is what our 'Find routes' tool is for.
'Find routes' exposes all published 'Routes' information that may be of interest for a specific passage. This is easily achieved by selecting where you are, or a nearest Haven, and the desired destination, or its nearest Haven. Then click 'Go' and 'Find routes' does the rest.
