doobie 5,802 Posted January 17, 2016 Report Share Posted January 17, 2016 So, tomorrow I'll be fishing in the morning and watched the news weather for winds etc. But there are differences between C7 and other links. Channel 7 (metro waters) High tide 9.20am / 1.64 m Willy Weather (Pt Noarlunga) High tide 9.09am / 1.64 m BOM (Pt Noarlunga) High tide 9.00am / 1.4 m Tides4fishing (Pt Noarlunga) High tide 9.05am / 1.3 m ok, clutching at straws a little, as tides/times are not that far out, apart from C7 with a minimum 11 minutes 'out'. But only c7 and WW have the same tide height. It's not a big deal from a fishing point of view as what's 5 minutes here or there and .2mt difference in height, but I would have thought that all tides/times would have been obtained from BOM. Just weird, that's all. bjorn2fish and Moggy23 2 Quote Link to post Share on other sites
Kuerschie 2,309 Posted January 17, 2016 Report Share Posted January 17, 2016 Channel 7 might be taking their tides from another location such as west beach or even north haven. That would explain why the time is 11 minutes later as the water pushes up the gulf. But yes I normally stick to the BOM for the weather and tides, etc bjorn2fish and ASD14 2 Quote Link to post Share on other sites
Brankim 945 Posted January 17, 2016 Report Share Posted January 17, 2016 Think it's a lot to do with wind in this gulf... And the wind is a hard one to predict! Sometimes it speeds the tide up going in or out, or the other way. Or almost cancels it out even... And also makes it even higher or lower. I only know from prawning that even the marine radio, the one that's apparently most accurate for us to go by for determining weather it's unfishable (over 25knots) and gives announces it afew hours before we go, is not eaven 80% accurate on a good day and so close to the time, so I'm guessing over a day, it's open to the induviduals interpretation of all the data they go off. And nowhere near an exact science. But someone is always going to get it close to with so many different calls. I guess better than all being wrong most of the time😋 But that's just my opinion Quote Link to post Share on other sites
Rod 773 Posted January 17, 2016 Report Share Posted January 17, 2016 Yeah it's all just predictions, most people concentrate on the hour either side so a few minutes is neither here nor there It would be good if they could get the wind forecasts spot on though Cheers Rod Brankim 1 Quote Link to post Share on other sites
doobie 5,802 Posted January 18, 2016 Author Report Share Posted January 18, 2016 Yep, accept all the above, and that C7 seems to use outer harbor as their tide/time numbers - hence the time difference. But for the rest of them, it should be the same. Winds, yes, they could effect things, but when they are 'predicting' a time for high tide and a height days, months etc in advance, then they should be the same. On the day in questions, if there is high winds, then yes maybe it can differ, but leading up to to the day it has to be the same. As said, no big deal with it all, just seemed odd.

Moggy23 625 Posted January 19, 2016 Report Share Posted January 19, 2016 On the day in question I use the Fishing Log program which is based of the BOM site was Outer Harbor 9.20 am - 1.64 mtrs Pt Noarlunga 9.11 - 1.33 To me this is fairly normal as the tides change by time & height up & down the gulf, also west to east of the state The only place that seams to get out of sync from time to time is Cape Elizabeth doobie, JAYMAN and Tinker 3 Quote Link to post Share on other sites
Knackers 700 Posted January 26, 2016 Report Share Posted January 26, 2016 Why would you bother to go to any other site rather than the BOM for tides? Every other site gets their tides from the BOM. When you look at sites such as willy weather all you are getting is the BOM data and any finger faults that they may have made. And I have found they make all sorts of errors. There was another tide thread where I posted examples of willy weather mistakes. From willy weather: Data Sources Weather information based on data supplied by the BoM Moggy23 and doobie 2 Quote Link to post Share on other sites
doobie 5,802 Posted January 26, 2016 Author Report Share Posted January 26, 2016 Yeah you're right Knackers. I was just putting it our there to show how can these be wrong/different when they all get them from BOM as you say. I used to look at WW but not anymore, jus BOM.

Rod 773 Posted January 26, 2016 Report Share Posted January 26, 2016 Why would you bother to go to any other site rather than the BOM for tides? I find it much easier when the info is displayed graphically. I can look through a months worth of tides and get a good idea of whats happening in about a minute. BOM only provides (as far as I know) pages of numbers and would be almost impossible. . Here's just 2 days of each as an example. Each to their own though Cheers Rod doobie 1 Quote Link to post Share on other sites
plankton 725 Posted January 26, 2016 Report Share Posted January 26, 2016 I don't mind Willy Weather, I've never noticed the tides being far enough off to make a difference to me, and I fish the Onk a lot and the tides are wacky there anyway. I also like the graphic representation you get on WW, which not only displays tides but wind, temp. and whatever else you want. Makes it easy to compare several weather variables and choose a good fishing time. Of course when the forecast turns out to be incorrect everything goes out the window, but that's fishing, and over the years I've learned more when fishing in the "wrong" conditions. doobie 1 Quote Link to post Share on other sites

I have found that their tide data, because they can't seem to copy from the BOM correctly, or use some crap data extraction it is consistently wrong. So with willy weather for me it is - they put shit in - they put shit out. People use it because it is a good app on an smartphone but I have found the data and forecasts on it to be consistently crap. Keep using it by all means but check the BOM from time to time to keep the em honest. doobie 1 Quote Link to post Share on other sites
Rod 773 Posted January 26, 2016 Report Share Posted January 26, 2016 No worries knackers, I don't use willy weather either. The program I use (wtides) I have found accurate enough to me and tide data is very important to my fishing. Sorry if I'm repeating myself Cheers Rod doobie 1 Quote Link to post Share on other sites

To be honest, at the risk of repeating as well, I do use the willy weather graphs up here in the NT as most of the ramps are only usable at a certain height of tide. If the tide data is right the graphs are usually accruate to 30 mins either side. Worst case was an hour later which put me retrieving in the dark. I always have a hard copy from the BOM website as well adjusted for the spot I'm fishing. I extract them from the BOM into excel and then add/subract to get the right tides. doobie 1 Quote Link to post Share on other sites
Des 838 Posted January 28, 2016 Report Share Posted January 28, 2016 BOM is the bomb! The "meteye" section is brilliant, for detailed long range forecasting. http://www.bom.gov.au/australia/meteye/ Zoom into the map for your area. Click on your spot and look at the 3 hourly detailed forecast for the next 7 days . Nobody beats that. Nobody beats their accuracy as they own the weather stations. They have first use of the freshest data. I use Seabreeze for a graphical overview. But if you are serious, then tunnel into the detail on BOM. Your life might depend on it one day!
