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. Future tidal planning is best accomplished by using Ballycastle's future tides predictor below.
The above image represents the current tidal streams offshore of this haven. Streams attaining three knots and above are highlighted by red arrows
Do you need more information on the tidal graphics?
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.

The tides in Rathlin Sound are very strong, have several eddies and are subject to great variations both in force and direction. Tides run from 6 knots at springs, to 4 knots at neaps causing strong eddies along the shores, with heavy overfalls off all the headlands. For those approaching from the south, close in off Torr Head the Ebb runs up to 9 knots during Spring tides.

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 Ballycastle Bay offset -01:00.
