I note that fishing times are supposed to be exellent today the 8/10/18 the best time was suposed to be aprox 11 to 2 the tide is showing yamba time ,i am fishing between LAWRENCE and BRUSHGROVE on the Clarence river where the tide is usually 4 to 5 hours later, does this matter
I am able to select Lower Southgate as a location if that helps
Lower Southgate and Yamba look very close time and tide wise. It looks to me that the river is using the same tide station as Yamba...
For the tides, it might just have to be a manual calculation on your part. If there is only the one tide station in the area there is not much can be done. But 4 to 5 hours difference seems a lot. It is only 34km by road so I am guessing 30 to 40km by boat.
I do understand what you are asking. Fishing times are usually pretty close over short distance. It is not till you get out to about 100 to 150km from your chosen location before you notice any real change. So the fishing times for your location being the same as Yamba is quite normal.
But the tide, of course is the issue. Tides are about 6 hours apart (I do state about ). So if you really do have about 5 hour difference, when it is high tide at Yamba it would be low tide at Lower Southgate. So looking at the tide clock the times would be very close, only the high would be a low for you and vise versa. Really the difference between 5 and 6 hours when it comes to tides is very small.
To answer your direct question...No, I don't think it would make a big difference. Because the tides are so close together (albeit reversed) so too will be the fishing times.
