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 Portsmouth +6. Because of this we only enable today's tidal stream chartlets to advance 24 hours.
Future tidal planning is best accomplished by using Haslar 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.
Future tidal planning is best accomplished by using Haslar Marina'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.

The maximum currents are usually experienced on the ebb when spring rates may reach 5.5 knots in the harbour entrance, about 3 hours and 30 minutes after HW. During maximum ebb little headway can be made at the narrows and it is best to avoid arriving at these times.
There is ¾ of an hour slack in the entrance during the second and third hours of the flood. A counter-current runs along the western edge of the channel just inside the entrance on the flood. The direction of the out-going stream in the entrance to the harbour is towards Hamilton Bank and a specific allowance should be made for this dangerous set.
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:

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 Portsmouth offset -01:00.

The above wind speeds are expressed in the Beaufort scale. Red indicates strong winds of 6 or higher.
Headline: Feeling cold with plenty of autumnal sunshine.
Today: A cold and start with some frost in places. Any early morning fog will clear through the morning, leaving a fine afternoon with sunny spells and a chance of some showers in the far east. Feeling cold with light winds. Maximum Temperature 5C.
Tonight: Clear skies overnight which means it will be turning very cold with a widespread sharp frost, and some icy stretches possible. Mist and freezing fog patches possible too. Minimum Temperature -2C.
Thursday: Another cold and frosty start but largely dry with some autumnal sunshine once mist and fog clears. Perhaps the odd shower in the far east. Feeling cold in the breeze. Maximum Temperature 4C.
Outlook for Friday to Sunday: Largely dry with some early morning mist and fog around at times. Feeling cold with overnight frosts and showers in the far east, perhaps falling as sleet over high ground.

Coastguard on VHF Channel 16 and this should only be used for distress and urgency calls. Most coastal areas have a good phone signal making it possible to dial 999 or 112 and ask for the coastguard. HM Coastguards Solent area ‘Maritime Rescue Coordination Centre’ MRCC is situated at Lee-on-Solent; MMSI is 002320011. The centre is manned 24x7 and has a rescue helicopter at its disposal. They keep a watch on VHF Ch 16 and also Ch 67 that can be used for routine communications. Solent Coastguard broadcasts a weather forecast on Ch 86 and Ch 23 once an initial announcement has been made on Ch 16.
Whilst operating in the Solent it is advisable to maintain a radio watch on the port working frequency of Channel 12 used by Southampton Vessel Traffic Services (VTS) and shipping. Every 2 hours from 0610-2210 there will be a broadcast on Channel 14, pre-empted by a transmission on Channel 12, giving information on large ship movements, local weather conditions and any new Navigational Warnings.
