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 Ballydorn and Down Cruising Club'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 Ballydorn and Down Cruising Club'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.

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

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 Strangford offset -01:00.

The above wind speeds are expressed in the Beaufort scale. Red indicates strong winds of 6 or higher.
Headline: Occasional rain initially, becoming confined to west for afternoon.
Today: A cloudy morning with occasional light rain, perhaps the odd heavier outbreak also. Rain becoming confined east of Lough Neagh by noon, with some brighter spells developing late afternoon across eastern districts. South to southeast winds brisk around the coasts. Maximum Temperature 17C.
Tonight: Occasional rain in the west extending across all parts from midnight with heavier outbreaks developing overnight. South to southeast winds strong around the coasts. Minimum Temperature 8C.
Sunday: An overcast morning with rain that turns heavy for a time late morning and early afternoon, before clearing from the southwest late afternoon. South to southeast winds strong at first. Maximum Temperature 16C.
Outlook for Monday to Wednesday: Unsettled with showers and longer periods of rain crossing from the south through the start of next week.
