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 Dartmouth 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.
Future tidal planning is best accomplished by using Dartmouth Harbour'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
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 DARTMOUTH offset -01:00.

The above wind speeds are expressed in the Beaufort scale. Red indicates strong winds of 6 or higher.
Headline: Showers merging into heavy and persistent rain overnight.
This Evening and Tonight: Turning very wet this evening with persistent and heavy rain developing widely across the region. This may give localised flooding overnight, most likely in eastern counties of the region. Chilly but staying frost free. Windy at times, especially on coasts. Minimum Temperature 4C.
Monday: A generally wet day with periods of heavy rain, and the chance of some localised flooding. Breezy at times and especially windy in Cornwall. Temperatures around average but feeling chilly. Maximum Temperature 8C.
Outlook for Tuesday to Thursday: Brightening up through Tuesday with sunny spells. Largely fine on Wednesday after frost and freezing fog clears. Becoming windier and milder on Thursday with some heavy rain. Chilly at first.

• Alternatively, where a good phone signal exists, dial 999 and ask for the coastguard.
• If at sea, use the Global Maritime Distress and Safety System (GMDSS) to make a distress or urgency alert.
The National Maritime Operations Centre (NMOC) based at Fareham handles all operations in the area from Sussex, Hampshire, Isle of Wight, Dorset and Devon. They also assist other authorities such as the Police, Fire and Ambulance with their specialist expertise. The centre is manned 24x7 and has helicopters, based at rescue bases at Portland or Lee-On-Solent, at their disposal. Ch.67 can be used for routine communications and the National Maritime Operations Centre can be contacted directly on +44 23 8032 9486 for administrative enquiries only. Dartmouth Maritime Rescue Sub Centre with its all-weather lifeboat is situated at Kings Quay and an inshore lifeboat is stationed in Tor Bay.
Phone 999 when it is a Police emergency, such as when a crime is in progress, someone suspected of a crime is nearby, when there is a danger to life or when violence is being used or threatened. Phone 101, the police non-emergency number, when it's less urgent than a 999 call.
