We post six months worth of tides for each location. The clickable maps on the tide index pages are for the current month (now May - or whenever...). For other months just scroll down the page to the text links. If the clickable map isn't May - or whatever... then "refresh" your browser.

Notice on Mon the 7th the 1st high is at 11:29 in the morning and the second is 11:47pm (13 minutes before midnight).
On the following day (the 8th) the previous 11:29am tide becomes a 12:15pm tide. While the previous 11:47pm tide doesn't reoccur until 12:31am (31 minutes after midnight) on the 9th.
Therefore no am high tide on the 8th. However, notice that the actual time between 11:47pm on the 7th and 12:31am on the 9th is only 24 hours and 44 minutes - close to the average of a tidal day.
Another tip off - notice the tide heights as they switch from am to pm or vise-versa.
