Tide data kindly provided by Tides Times.


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.


Tidal Hour:

(Dover)




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 Smerwick Harbour'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.

Today's Dover tides — High waters: 00:59, 13:21, Low waters: 08:32, 20:44
We are now approaching the next tidal event that will be Neaps.
MHWS: 3.8m, MHWN: 2.8m.
More accurately Cobh -0107sp, -0027np

Tidal streams run in line with the direction of the coast and across the entrance to Smerwick Harbour
Dover – 0100, Cobh + 0450, Northeast going, spring rate of 1 to 1.5 kn
Dover + 0500, Cobh - 0135, Southwest going, spring rate of 1 to 1.5 kn

Between the Blasket Islands and Kerry Head, the currents set in the direction of the coast and across the entrances of Smerwick Harbour, and Brandon, Tralee, and Ballyheige Bays. The current setting northeast begins about 5 hours after HW at Galway and the opposite current about 1 hour 20 minutes before HW at Galway. The spring velocity in both directions is 1 to 1.5 knots.

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

Hour: -- 000102030405060708091011121314151617181920212223 Minute: -- 0001020304050607080910111213141516171819202122232425262728293031323334353637383940414243444546474849505152535455565758

Taking a mean tidal offset from Dover's tide, we expect your targetted date's associated local tide at to be:

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 Cobh offset -01:00.

  Advanced Haven Search

You are three steps from finding what you're looking for

Set your current location	Set the maximum distance you are prepared to travel	Check off what you want



Where are you?

We've assumed your desired starting location is "Smerwick Harbour, Kerry". Change location.
There are three ways to locate the start point of your search more information.
If it is a listed location, or there is a listed location nearby, simply select the county and haven to determine the search origin. Alternatively if you have a chart, plotter or GPS input the position in decimal degrees. Finally if you are there right now your computer may be able to automatically locate its current position via auto-locate.
There are three ways to get started; base your search from one of our listed locations, input a position, or let us try to automatically detect your current location.

The described position in step one will centre a search and the range sets the radius of a circular search area. All suitable targets, in all directions, within the direct point-to-point or aerial transit path of the range will be presented. Because the search is based on this charted distance in most cases the actual sailing passages will require extra mileage to circumvent navigational obstacles.

Specific shelter


Describe the sectors you want sheltered, where you expect the wind to blow from. You may manually input each by checking the compass points or auto-fill by checking the required days on this location's five day weather forecast, more information.
You may also use a combination of both manual and forecast auto-fill to add additional sectors. Please note that the forecast auto-fill adds one compass point on either side of the forecast to allow for variability. The grey segments in the compass rose provide a visual summary of the shelter construct.

Please note that forecast auto-fill adds one compass point on either side of the forecast to allow for variability.


Level of protection


You may refine your search to specify a minimum level of protection, more information.
Quality of shelter is characterised from one to five stars and are described below. All levels are selected by default and you can set what is appropriate by checking the minimum star rating level. If you do not set a minimum level all havens that cover the requested quadrants will be presented irrespective of the quality of the shelter provided.
Specifying the minimum level of protection is important as this may vary significantly depending upon what it is needed for and the prevailing conditions. For instance, if conditions are moderate and it is simply needed for a lunch stop, most all locations from one star will be suitable. When looking for a location to stay overnight in comfort it would be more appropriate to select a three star minimum. Or when seeking shelter in rough conditions a minimum of four stars would be best. All of these depend upon what you are personally comfortable with, plus the capabilities of the vessel and crew.


Check the minimum
level of protection

		Complete protection; all-round shelter in all reasonable conditions.
		Good; assured night's sleep except from specific quarters.
		Tolerable; in suitable conditions a vessel may be left unwatched and an overnight stay.
		Exposed; unattended vessels should be watched from the shore and a comfortable overnight stay is unlikely.
		Stay-aboard; lunch stop or tide-wait exposed or tenacious holding location where a vessel should not be left unattended.


Ease of access


You may refine your search to the set how easy seaward access is to the resources, more information.
Approaches to the shelter are also characterised from one to five stars. All access levels are selected by default and the minimum level of access complexity may be chosen by clicking the appropriate minimum star rating.
This minimum level of access complexity may vary significantly depending upon the time available, the vessel and skill levels of the crew plus the prevailing conditions. For instance, if conditions are moderate, plus time and experience are plentiful, the one star minimum could be the most suitable option for the adventurous sailor. If conditions are more developed, but the visibility is good, a three star minimum could be the best fit. Or when seeking shelter in heavy weather conditions a four stars access minimum may be best. All of these depend upon what you are personally comfortable with, plus the capabilities of the vessel and crew.


Check the minimum
ease of access

		Safe access; all reasonable conditions.
		Straightforward; when unaffected by weather from difficult quadrants or tidal consideration, no overly complex dangers.
		Attentive navigation; daylight access with dangers that need attention.
		Careful navigation; good visibility and conditions with dangers that require careful navigation.
		Highly involved navigation; complex dangers that require arduous navigation, good visibility and settled conditions.
