Please use tidal harmonic predictions with a sensible margin of safety. The effect of air pressure on tidal height can be substantial. Tide tables assume a standard pressure of 1013 hectoPascal (hPa). One hPa, or millibar, variation from that will change the sea level by one centimetre. Mean sea levels may also be raised or lowered by strong winds depending upon the topographical features of the area.

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 Bangor Harbour & Marina's future tides predictor below.

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.

Tidal planning for vessels approaching Belfast Lough is essential. Vessels approaching from the south will encounter tides that run hard in the sounds. Likewise, vessels approaching from east, or outside the island group, will encounter races with overfalls as they close in on the Copeland Island group. At the eastern tip of Mew Island the ‘Ram Race’ initiates and extends 1.5 miles south-by-southeast on the flood and up to 1.75 miles north-by-northwest on the ebb.
From Dover HW +0455 to -0115 (Belfast HW +0510 to -0100) the tide floods southeast. Donaghadee Sound’s spring streams can in places reach up to 4.5 knots in both directions making a favourable tide transit a prerequisite for most leisure craft. Streams largely follow the direction of the channel but it should be noted heavy tide rips in a big seaway may cause overfalls to occur across the southeast end of Donaghadee Sound. From the entrance of Strangford Lough, however, through to the inner passage, the stream is comparatively weak, not averaging more than 1.5 knots on springs.
Copeland Sound tides are not as strong but still attain rates of up to 2.5 knots with Spring tides. This is however not the preferred channel owing to the two challenging and unmarked rocky shoals called ‘Platters’ and ‘Ninaen Bushes’, the latter, with less than a metre of cover, is situated out half a mile off from the north-east point of Copeland Island. Eddies are very strong elsewhere all around the islands group.
Outside the islands, the tides turn about one hour later. On the south going flood, a vast eddy forms to the south of Mew Island. This circles back on itself in the five-mile area between the entrance to Donaghadee Sound and Ballyferis Point. Hence the streams off Donaghadee Harbour are 1.5 kn rotary in a clockwise direction on the flood. However, when this vast circular eddy of water courses around to collide with the flood tide to the south-southeast of Mew, the ill-famed Ram Race shows its true colours. Thus the area is at its worst after the recirculation on the second half of the flood circa HW Dover -0230 to +0015 or about local HW (HW Belfast -0215 to +0030 or about local HW). Likewise, the north-northwest race occurs on the latter half of the ebb from HW Dover +0330 to +0630 (HW Belfast +0345 to +0615 or about local LW).
Northern approaches are less complicated, however tidal streams remain very strong running up to 5 or 6 kn off salient points to the north of Belfast Lough.
Between Black Head and White Head tidal streams are negligible with light currents, the flood running in and the ebb running out of the lough off Carrickfergus. In the middle to the outer half of the lough tidal streams rotate and are always less than 1 knot.
Calculate future 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 Bangor offset -01:00.

Headline: Bright spells and scattered showers through Monday.
This Evening and Tonight: Cloudy with outbreaks of rain across County Antrim soon clears to leave the evening dry with clear spells, perhaps the odd fog patch developing. Overnight a narrow band of occasionally heavy rain pushes northeast, affecting all areas by dawn. Minimum Temperature 6C.
Monday: Cloudy start with any remaining rain soon clearing to leave a bright day with sunny spells, although towards midday showers will develop and become heavy at times for the afternoon. Maximum Temperature 16C.
Outlook for Tuesday to Thursday: Rather cloudy with showers or longer spells of occasionally heavy rain through Tuesday and Wednesday. Drier and brighter on Thursday but colder as winds turn more northerly.
