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 Helen’s Bay'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.
Future tidal planning is best accomplished by using Helen’s Bay'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 is essential for vessels approaching Belfast Lough and a set of notes can be found in the Bangor Harbour [lpin] entry.
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
Hour:
Minute:
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 Belfast offset -01:00.

Headline: Mostly cloudy today, a few showers in the west.
Today: This morning will be cloudy with patchy rain, this mainly across the west. Remaining rather cloudy this afternoon with some showery rain across the west. Eastern counties mainly dry. Feeling somewhat warmer. Maximum Temperature 13C.
Tonight: This evening will be cloudy with showery rain in the west. Then remaining cloudy for the rest of the night with showery rain becoming more widespread. Minimum Temperature 7C.
Monday: A cloudy start with some rain. Then rather cloudy for most of the day with a few showers, brightening up from the west later. Maximum Temperature 13C.
Outlook for Tuesday to Thursday: Cloudy on Tuesday with a chance of rain later. Then Wednesday and Thursday will be dry although fairly cloudy.
