I have a feeling you can get tide info from the BBC website somewhere.
Possibly via the Weather section......

Most Marinas and a lot of Chandlers have a local tide table on the
counter as a feeby. Pick one up and when you are away from home
look up 'high tide for the day' on a website or the local and work
out the offset (ie: half an hour before... etc.)

It won't be exact but it's near enough unless you're in the Solent
where a mile up the coast is a different planet.

I find this site useful:

I produce Spring and Neap tide graphs for the year at;

http://www.cardiffbsac.org/tides/

The tide heights down the side of the graphs denote heights in Cardiff,
but the dates along the bottom are correct for anywhere in the UK.

For those not used to seeing this type of graph, the higher the curve,
the bigger the spring tide, the faster the tidal flow, Consequently the
smaller the curve, the smaller the neap, the slower the tidal flow.

Towards the end of the year I will produce more graphs for next year.
