this site is excellent for tables of tides for menai bridge run by the Bangor uni marine sciences dept I think. Just go to the site with a smart phone. Or take a photo with an iPhone of the website page with months predictions then it is stored. (navigate to page then do a screen photo by pressing the on off button at the same time as the main round button, go to photos and you will find a photo of the web page!)
there must be info for other areas on there.
