arpie Posted September 20, 2007 Share Posted September 20, 2007 Hi guys I always thought the tides were roughly 12 hrs apart plus 15min-30mins per tide, therefore changed from one day to the next by about an hour! So I would have expected a 7.20am low to be at about 7.40pm low on the same day. Checking out the current tides, today has low tide this morning at 7.20am, but the evening low tide at 21.30 - making it a 14hr turn around? The high tide this morning is 1.55am then 14.15 which is a 12hr turnaround (give or take a few mins) My tide watch basically follows the 12hr (plus some mins) principle. Checking my printed tide chart, the low tide often shows more than 12 hrs change in time, but some show less as well!! July 5th, eg, shows morning low at 0545 & evening low at 1726!

tiger_shark Posted September 20, 2007 Share Posted September 20, 2007 Tides work on the position of the sun and the moon.... Its not a regular pattern. Link to comment Share on other sites More sharing options...

arpie Posted September 20, 2007 Author Share Posted September 20, 2007 Thanks RObbie Some good info there. I usually expect the low tides here in the estuary to be up to 3hrs after Sydney time (especially when there are the big tides trying to get in & out) but guestimate them normally to be about 2hrs difference. Looks like I need to consult the actual charts more, rather than relying just on my watch! Up till now, I've been happy with it & only had to wait the odd long time for the tide to change. Looks like I would then have to allow up to 4-5hrs difference at times!! It is not as if the tides just now are extraordinarily high!! Hi Jewgaffer! I can see you clicked on Tide (disambiguation)!! Hope you enjoyed the music! Good luck at Mona Vale! Cheers Roberta Link to comment Share on other sites More sharing options...
