We now have agreement from the UK Hydrological Office that we can publish tide data for members' use - it must not be further distributed. You can therefore download a PDF (213kB) of the tide table included in the 2017 programme. This is stored in the members' area of the website so you will need the login details.
BBC tidal information for Wales (nearest port 483a Criccieth)
UK Hydrological office information for Porthmadog - but no tidal curve or LW information, which is available for Criccieth, but this information mirrors the BBC information (or, rather, vice versa). Note that the UKHO site requires you to enter the summer time adjustment of 1 hour in the box in the top right corner.
