Does anyone make a DIURNAL Tide Watch (1 HI & 1 LO per day)?<br />All the Casio watches are Semi-Diurnal Tide Watches (2 HI's & 2 LO's per day) and they WILL NOT display the correct tide in the Gulf of Mexico or anywhere in the world that has Diurnal Tides. (Odd, because Casio is located in Japan and they have ONLY DIURNAL tides there!).<br /><br />THX!
......after more research, the only watches I see that have the remote possibility to display accurate GULF COAST tides are the pre-progammed ones (RipCurl, Nixon, Freestyle,etc). Unless you live in one of the stored locations, then chances are, you will not get accurate data from these either. The RipCurl does have a feature that allows you to create your location (X SPOT) and it will forecast your tide based on tide data from one of the nearby stored locations. It basically adds a correction factor to the tide times. The problem is, the GULF COAST has a combination of Diurnal and MIXEDS SEMI-DIURNAL tides and the tide times in locations as little as 50 miles from each other have nothing in common and there is no correction factor that will work. The tide data for your exact location MUST be programmed into the watch from an accurate tide data base for that exact location. There are 200 stored locations world wide for the RipCurls watches AND only 3 are GULF COAST stored locations. I have requested to RipCurl to please have more GULF COAST locations input into their programs at next revision. Until then, hard tide charts, tide apps for your smart phone or tide prediction websites are the ONLY way to obtain accurate GULF COAST tide data that I can see! RipCurl, are you listening?
I've never used a tide watch so I can't help you out there, but can anyone tell me why Japan would only have diurnal tides? Every time I think I understand more about tides something trips me up.
Hi Willi. Whatcha doin thinkin about the tides way up there in May-Retta? They still got the big chicken there? Lived in ATL for 20+ yrs. On the tide watches, serious question... No, I mean it. Serious. Why do people wear 'em? It seems neato and all, but how does it help? I guess it's for when you can't look it up on the interwebs, newspaper, etc?
Oh, I guess there is a good reason for me to get a tide watch. Sometimes us "senior" members forget sh**. I'm old, and the 70s were fun. Look up the tide online, and forget what time it said 5 minutes later. Was gonna mention this in earlier post, but I forgot.
Japan and many other places on earth have DIURNAL (1 high and 1 low/day) tides because of the laws of physics! If there were no land masses on earth and it were covered entirely by water, ALL tides would be SEMI-DIURNAL (2 highs and 2 lows/day) because the natural gravitational pull combination of the sun and the moon would produce even tidal waves that move unrestricted by land masses as earth turns! Land masses block and redirect tidal wave flows, causing them to become altered and uneven.

I want one to keep up with the tide status when fishing from my boat in shallow flats and bays in the Gulf of Mexico. When fishing shallow flats, you MUST move out BEFORE the tides gets to low or you could be trapped for hours with no way out. I do a lot of wade fishing and you can loose track of time very easily when walking the flats up to a mile away from your anchored boat. Oh YES, the BIG CHICKEN is still here!
Same thing in the Florida Keys. One side of the bridge (ocean side ) will be 4 hours off the bay side due to most of the water funnels in and out of Florida Bay north of Key West, so if you are in the middle keys like Marathon, it takes a long time for water to travel. All the reports are wrong, I have a tide clock on my wall that I try to reset every full moon for best accuracy but winds, currents, moon phase and Santaria still throw it off a bit here and there. If you have to have an exact tide due to surfing near an inlet, or diving in an inlet, and want to get the exact time of the slack tide, you have to look first person for a day or two before hand to get the timing just right. So how is some computer program going to do this?
I don't know, I looked at the chart there and it looks like Japan (aside from Hokkaido) has mixed semidiurnal tides, and then I looked at Surfline reports and that seems to be the case.
idk if it has it- but I have a classic shark tide watch that has been abused for years and keeps working. 2nd battery now... works great for #Belmar oh and its cheap on amazon.com
After looking at the NIXON on line manual, I see only 1 Gulf Coast location, Galveston Texas. I need a watch that will accurately display tide data for Port St Joe and Cape San Blas Florida (on the Gulf). The tides in Galveston Texas are 90% of the days SEMI-DIURNAL (2 highs and 2 lows/day). 10% of the days, the tides become DIURNAL (1 high and 1 low/day). Will the NIXON correctly show the tides times for ALL DAYS in Galveston? The tides at Port St Joe and Cape San Blas are no where near the mix of SEMI-DIURNAL and DIURNAL of the tides at Galveston Texas and as a result, there is NO correction factor that will produce accurate tide data for my locations. It is becoming more and more evident to me, that pre-programmed tide watches will be only accurate for their pre-prgrammed exact locations. The Nixon is a nice looking watch and I am sure they are probably fairly accurate for their pre-programmed locations! What is the location where you use your NIXON? Does it accurately show tide times that match the tide charts for your area? THANKS!
I can't speak for the accuracy of the map , but there are yellow, blue and red lines all around Japan indicating all the tides are present in the general area. The tides in Japan are of no interest to me personally. Bottom line, there are 3 types on tide on earth, DIURNAL, SEMI-DIRURNAL and MIXED SEMI-DIURNAL.
I have been asking that exact question to RipCurl and have yet to get a straight forward answer. THE ONLY way it can produce the erratic tide times you and I see, is to have the EXACT hard date and time tide time data from an accurate tide chart downloaded into the memory chip in side the watch......which is exactly what RipCurl states they do for all their pre-programmed locations! It will only be good for 10 years or so, because the chip physical tiny size, can only hold so much data The problem is, if your exact location is not there, the watch will not work for you! I checked the NOAA tide chart data AND the SWELL INFO data on this site for my area of Cape San Blas and it is very accurate! I want a watch that will do the same! Yes, you can bet a properly programmed memory chip can easily display tide data times based and matched to an exact date, time and location it is displaying...no problem!
