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.
(Manual calculation)
(Portsmouth)
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 Osborne 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.

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.

We are now approaching the next tidal event that will be Neaps.

Cowes has a Double High Water at or near Springs, outside of this the stand lasts for up to two hours. Our estimate is based on the above mean level that is targeted at the middle of the stand. For more accuracy HW Springs at Cowes are 15 minutes before and High Water Neaps 15 minutes after HW Portsmouth. LW Neaps are 20 minutes before and Springs the same as LW Portsmouth. For those using Dover tide tables HW Cowes is approximately 21 minutes after HW Dover.
Tidal streams run generally in the direction of the channel, both north and south of Ryde Middle. +0420 HW Portsmouth (Dover +0445) they run ESE, –0130 HW Portsmouth (Dover -0105) they run WNW. The maximum east going rate during Springs is 2 kn and Neaps is 1 kn. The maximum west north west going rates are 2½ kn and 1¼kn, respectively.
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
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 COWES offset -01:00.

Headline: Cold. Mostly dry and cloudy.
This Evening and Tonight: Generally cloudy overnight but largely dry. Cold, with a risk of one or two very isolated frost and fog patches developing, should there be any clear spells. Winds remaining light. Minimum Temperature 1C.
Saturday: Cold and rather murky. Widely cloudy, though perhaps a few brighter spells developing in the west during the day. Generally dry but perhaps a few snow grains falling. Maximum Temperature 4C.
Outlook for Sunday to Tuesday: Chilly with variable cloud but some clear or sunny spells through this period. Risk of overnight frosts and some freezing fog patches.

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.
