  • Some Interesting Info on Tide Direction and Speeds

    Well I found it interesting anyway.

    Looking at some charts for our coast, I noticed the tide info on them. The table shows spring tide direction and speed in relation to HW at North Shields.
    I always thought the tide would slow and change direction as it reached high or low water but the Admiralty charts show otherwise. It may make a difference when deciding to stick around fishing a fast drift.

    I've noticed that when I'm out fishing the wrecks , I hadn't realised why , but on my plotter if it's showing high tide at say 2pm , the drift dosn't stop for ages after that , I wondered if it was to do with being further offshore but I guess it's down to momentum , it must take a while to stop all that water moving and turn it in the opposite direction.

      there is a difference in the time of high and low water when you are further out, and have a feeling that the chart above relates more to the seas current north to south and vice versa rather than the tides or does it state tides at the begginning of the chapter.

        tides

        theres somwhere around an hour difference depending on how far off shore,possibly a lot more for the 20 mile lads.the tide is an interesting subject and more than a little complicated when it comes to doing tidal predictions etc so many things affect it wind direction, strength springs neaps etc etc i think the yacht lads tend to be a bit more knowledgeable on such matters

          I used to say there was a two hour difference for the 10-12 mile wrecks
          A bit of info for you it takes the worlds seas 500 years to circulate, the ice flows that cause this circulation by melting an dfreezing have been out of operation for a few years, if the seas stopped circulating they would become a stagnent mess, but it would take a long time to stop, think we are ok, although some think me and Sam have been around before Adam and Eve, that's before anybody else gets in.

            The numbers were taken from an Admiralty chart and are titled “Tidal Streams referred to HW at river Tyne (North Shields).”
            It’s odd that the time the tide changes direction doesn’t correspond with the time of max / min speed. Looking at other flow and direction lists shows you’re right that the tide’s change in direction and speed are affected by how far north or west you go.

              it affects the shore as well, there is 45 minutes difference in tides from Budle Bay to the Tyne. Try and look at the sea as a bath of water sloshing about, it can not be high or low tide everywhere at the same time

                Tides.

                Alan I was around when Pontius was a pilot. When I joined the R.A.F. we still used crossbows.
