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.
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.

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.

Headline: Sunny spells with showers developing.
Today: A dry and bright start with some good spells of sunshine around but cloud bubbling up through the morning with showers developing. The showers, with light winds, will be slow moving and become occasionally heavy for a time this afternoon. Maximum Temperature 15C.
Tonight: Showers largely die out this evening to leave some late sunny then long clear spells overnight. With light winds it will turn quite chilly with mist and fog patches developing. Minimum Temperature 3C.
Tuesday: Any fog soon clearing to leave a fine start with good sunny spells. However showers are expected to develop through the morning with the odd heavy one in the afternoon. Maximum Temperature 15C.
Outlook for Wednesday to Friday: Rather cloudy start Wednesday with showers but brighter later. Cloudy Thursday with outbreaks of rain, occasionally heavy later and strengthening winds. Further rain or showers on Friday.
