I was mind blown when I found out the SST's in my area were on 25.3c, I thought this may have been a malfunction so I checked other parts of the coast and Bondi is the same and Newcastle comfortably on 26c. Even the far south coast(Eden) is just under 24.

Does anyone know what is causing the SST's are so high and places as far south as Moruya are nudging 26? Especially with the upcoming El Nino that would normally cause lower that normal SST's

It is the East Australia current. Nothing too unusual about it in my experience.

In this instance the currents and eddies have just lined up correctly to create an express service direct from the Coral Sea. You can see it on the IMOS images here.

During Summer it was the opposite; the eddies were doing their best to deflect the warm current away from the NSW coast.

Thanks for that explanation kizz, I know the EAC plays a part in it, but I was just surprised that SST's we that high. And just a silly question what are the "eddies"?

The eddies are the circular 'whirlpools' of water. I think of them like the atmospheric pressure systems.

Look at the maps and you see arrows indicating clockwise eddies where the water level is lower and vice versa.

Oh cool thanks for that, all the eddies are obviously in the right place to make for a strong current from Queensland, hopefully the water stays warm right into winter.

Yep definitely the East Australia Current! I didn't even know it existed - until I first watched the Disney Pixar movie Finding Nemo while in Queensland way back in September/October 2007! smile

In my experience I've been holidaying at Merimbula on the NSW South Coast for about 7-10 days or so every January since 2006, and I've noticed that the water temperature at the Main Beach is quite variable. Some years it's been very cold, leaving you chilled almost to the bone. But other years it's warmer, just right for enjoying the waves! smile

No doubt the East Australia Current plays some role in the water temperature at Merimbula but I'm sure that other factors like El Nino and La Nina might also be involved. smile

Thanks for your input ASF and I didn't know about it until I watched either smile

And living here in my experience most years the SST's get to about 22-23 in around February/March and usually stay warm until June unless sustained cold fronts come early and bring upwelling from the offshore winds.

But the last couple of years is weird to me, it got to 25 last year in March and this summer it nudged 26 about a week ago, but yet most of summer the SST's were around 20 and felt quite bone chilling some days!!

Cheers Reillyp! Mind you for the most part whenever I'm in Merimbula the water temperature averages around 20C, fluctuating by about 1-2C either side of that mark depending on when I visit (some years are markedly colder and others are warmer as I said earlier). But I think the water is at its warmest in February/March... but I'm not in town at the time unfortunately.
