Evening,
Does anyone know of a website or app that displays tidal curves rather than numbers, also for 2 or 3 months ahead. Area SW UK.
Also sun and moon rise and set
Thanks

Not websites but apps. Imray tides planner or Absolute tides will do this. May be a small charge for long range future views

If you can live with a tablet/phone app rather than a PC I recommend Absolute Tides. Gives everything you asked for. Closest SWSunk provided is Whitaker beacon.

(This comment may require correction from someone with more knowledge.)

I don't believe that the UKHO licences the harmonic data to create services which predict more than a week in advance. This means that all services that do so are using other data sources - which may well be good enough. You can get the Full Monty if you pay about £60 a year to the UKHO for Total Tide. I do, just because I like buggering around with software. No real sense in it. I am not allowed to build a service on it.

In many countries (including the notoriously capitalist USA) government hydrographic information, including charts, is simply made available in the public domain. Not so here. Were it so, many and diverse services would be built on it for people like you and me. I'd hesitate to criticise the UKHO for the policy, because I suspect they have been directed by government to sell the data. I'm sure they'd be glad to be funded in a way that made it unnecessary. A common economic argument for free use is that its stimulation of economic activity is more beneficial than selling the information restrictively. You decide. Of course, if your taxes pay for the UKHO and they may also contribute all the administrative bean counting necessary to the commercialisation of the UKHO. Or maybe they earn so much from sales that its worth all that. Your guess is as good as mine.

I guess my bias is showing... you have paid for this information already through tax.

Why do you need to see the curve? Asks inquisitive engineer. I tend to think in numbers when it comes to height of water.

It does. Absolute Tides (I use the Android version) uses licensed UKHO data, currently for the grand charge of £2.50 for the year.

Tide tables for standard and secondary ports; tidal curves; tidal streams; sunrise and sunset; moonrise, moonset and moonstate; and a link to the Met Office inshore waters forecast (if you have an internet connection). And a widget so that today's tides show on the phone screen.

I stand corrected. That is great.
 
I use wxtide. Free PC software that runs up to 2037. Does tidal curves for a good range of UK ports - but not UKHO ones. Once you get to know it, you can write in your own differences for the ports you want.
 
I would be very interested in tables that can display tidal currents. In many cases the direction and strength of the current is more important than the water level - and in many cases there is no obvious correlation between these two. Up to 3 hours shift is not uncommon.

So you mean set (direction) and rate (speed) of tide? My understanding of a current is very different to what you are describing.

The Imray Tides Planner one also uses UKHO data for a small fee to unlock each year. You can buy multiple years ahead if you want to.
