Hi,

Tides are a fuction of the moon and to an extent the sun in their relative position to the earth, so the highest tides occur when the moon and sun are on the same side of the earth (new moon) and the second highest when the moon and sun are on opposite sides (full moon.) In between you get smaller tides.

See the attached link for daily tidal chart.

I have tried to send you a link from the UK Hydo Office but unfortunately I am still a newbie. Try this:

Google search: UKHO- Easy tide
The port ID number for Hua Hin is 6878

Thanks for the response foxxee, but the real question is one tide one day and two tides the next day. Typically there is only one tide a day now suddenly it changes to twice a day. Just wondering why that happens.

Take a look http://easytide.ukho.gov.uk/EasyTide/Ea ... onLength=7

Norm,

One tide a day is called a “diurnal tide” and 2 tides a day is called a “semi diurnal tide” .
There is a very good explanation in: http://en.wikipedia.org/wiki/Tide

Thanks that is a good explaination. I assume that since Thursday is a new moon, which means no moon at all, and the sun must be in the right place to make it all happens. OK I won't blame it on Obama or aliens. (this time).

Semi-diurnal tides are found in many places around the world. Not unique to HH or the Gulf of Thailand.

The following URL will provide all the info you will ever want to know about tides and probably a lot you don't care about.

there was also a strange sun while I was there a couple of weeks ago, it had like a huge ring around it, almost like a rainbow around the sun but really wide, any one else see it?

That seems to happen a few times a year here. Explanation below. I think I only saw it once or twice in my life in the west. Pete :cheers:
