How come the water surface temperature seems to drop when we (= GC to Byron) get hot N /NW winds in spring?

Or am I just suffering from colourful memory, selective attention and/or insufficient maritime acumen?

I'm getting a bit desperate for waves, my plants are all shrivelling up and looking like they will die soon, the wind is hot from the north, and when I finally give up and enter the water to catch a wave (against better judgement), I end up freezing my butt off !!!

You'd think that northerly winds would blow some warmer northern waters down the east coast (along with Blue Bottles in it), but NAH! the water just gets colder each day. The Southport buoy reports 19degc now.

Please explain...

the consistent Northerlies cause the warm surface water to essentially bounce of the coastline and are replaced by cold stuff from the deep

Aha, thanks.

And why is it that the water gets all brown and murky even without any rain when the northerlies start? I suppose the different swell direction rearranges sandbanks and mud that had arranged themselves to be semi-stable in south-easterly swell directions? Last week the ocean looked like after mayor flooding, but no rain had fallen...

I've given up looking at the ocean in hopes to surf it.

I'd pay good bitchcoins for some waves

I heard Hawaii is nice this time of year.

OK this shit ain't funny anymore Huey!!

Agreed.
We need a human sacrifice.

7 days of black northerlies with more to come.

thats an impressive run.

I think this is a portent of the future under a hotter climate.

An increase in the size, timing and strength of the inland Australia heat low. This massive mass of super-heated air is now going to influence our climate, making it more continental and less maritime. Most notably through Spring/Summer. Changing the balance between land and sea temp gradients and leading to longer and stronger northerlies episodes.

So more lefts. Further proof that goofies are the chosen ones.

There's been a fair bit of modelling that supports that argument

That's it, I'm moving to Tasmania!!!

What are the surfing seasons for Tasmania like?

With a west facing, south facing and east facing coastline, you can't go wrong anytime of the year down there.

Even some decent stuff gets into the northern coast around Devonport and Burnie.

God's country.

easily the best place for a surfer to live in Oz, if they like long lonely sessions, don't mind finding other outlets for long flat spells and love big raw coastlines.

If I could find an old fashioned long sail board I'd buy one.

I can see a faint light at the end of the tunnel....thank feck!!!

think there's a bit of an undercall in forecast world re the deep sth fetch south of the Tasman Sea atm

that thing might surprise everyone south of Coffs on Friday
