Q:
Hi, I am from University of Ottawa, Canada and doing a project regarding to the effect of tides on submarine fibers at Bahamas. I search a lot on the internet about tide info and found your website. I belive you are experts on this area. It is greatly appreciated if you could help me out. Bahamas are the region between Caribbean Sea and Atlantic Ocean and has many islands around. I know that there are two high tides and low tides per 25 hours due to the interaction between earch,moon and sun. But in common sense, tide is up in the evening and tide is down in the earily morning. I never notice or hear that the tide is up at noon time. This problem bother me for a long time. Could you tell me what do you think about this? Thanks in advance. Good day!

We're confused by your sentences: "In common sense, tide is up in the evening and tide is down in the early morning. I never notice or hear that tide is up at noon time."

The lunar component of the tides is much stronger than the solar component, and since the moon appears in different places in the sky at the same time on different days, we expect that high tide can come at any time of day. I just checked (see below) the tides in Bermuda and found that today, high tide came at around noon.






with lots of links maintained by "an enthusiast, not an oceanographer". There are lots of computer programs designed to predict tide levels for various places in the world.
