looking for MHWI or Lunitidal Interval for Waterford Coast

DonalB

Hi all,
I'm not a sailor so don't have any Admiralty charts. I need the Lunitidal Interval or Mean High Water Interval for the Waterford Coast (preferably Tramore, Bunmahon, Dunmore or Dungarvan, in that order) to set a tide watch accurately.
I tried the UK Admiralty EasyTide website, but it was obv. written by poor coders as it doesn't play well with Firefox on Linux.
Any help appreciated.

Thanks michael,
I have waterford tide tables. What I don't know is is I use a period of figures, say a week, and calculate the MHWI from that, if that's accurate. MWHI & Lunitidal Interval, I think, are published seperately. Based on the longitude for waterford, I have figure of (I think, can't remember exactly, 5 1/2 hours. I'd like to double check that against a published MWHI.

Had a cursory glance over that but only saw Cobh and Dublin on it... Cobh is near enough what you worked out waterford to be, though.

Thanks. I'm a sea swimmer and I'd put a significant difference between Cobh and Waterford, both because of the east/west pull on the South Coast of the rising and falling tide and because Cobh is inside Cork bay. But thanks anyway.
