Hiya mate.
Regards the tidal flow. First of all you had the time wrong. The table quotes 2139 hrs, but you have to add the hour for Summer Time so it was 2239.. there`s an hour adrift straight away.
Then you have to take into account that the predicted time is for Gladstone Dock, which is almost 10 miles away, so the rising tide has to travel 10 miles down river before there`s any difference at Oglet.
I`d be tempted to add half an hour but as I`ve never fished there I couldn`t swear to it.

But you deffo forgot to add the hour. We`ve all done it lol
