Spike in water temp

[DaneCross]

Hey fellas,
Just checked out the Tweed water temp chart and noticed a big spike in temp jumping from 22deg to 24deg in less than an hour yesterday afternoon (see pic). I'm just curious as to your opinions on how fish would react to such change? Would there be a 'hot bite', would the fishing shut down or what??
Cheers,
DC

Gotta wonder if it would wake the fish up a bit being so sudden, and bring them on the bite eh. Would be interesting to know.

what time was the tide change?

[Maria]

Could have been tide related. Hit low tide around 16:45 that day on the seaway and the graph tends to indicate that spike between 15:30 and 16:30 or there abouts.

I think someone took a leak on the buoy

[SeaHunt]

Yep thunderbird , thats the only way I know to warm up sea water that fast..

[jeffo]

could have something to do with the currents pushing past a warmer pocket of water? although i cant say ive seen a temp line of 2 degrees ???

[thunnus]

anyone got access to the sea surface plots (the sat ones with all the pritty colours ), could just be a welling from the main current out wider.

The jump seems to be too sudden to be the river or tide ,, could be a calibration glitch.. We have used 'bottom' temp sensors before and you get that with them ..

the only other explanation is that a wider current line eddied in from the NE and then you may see that temp jump like that when the current line crossed the bouys path..but I believe the buoys are fairly shallow off the tweed and its rare to see those currents in that shallow

Dunno,, unless theres been a lot of beer available on the charter boats working that area...........

As far as the fishing goes a surface jump of two degrees wont affect your bottom dwellers and theres a good chance the current will bring the tuna close ,, for inshore fishing tho I have seen big temp rises "well above normal" affect the fishing for the worst ,, possibly because they shed fat reserves and dont need to eat as much ,, not sure

Shit ProFleet...some interesting ideas there mate - some things to think about in future.

I still believe someones letting out excess liquid

[PinHead]

it says sea surface temp..if actually on the surface then a warm breeze would do it..but if the sensor is under the water then forget it..cannot increase that temp in such a short time.

[mackmauler]

there were some amazing currents inshore yesterday, was like being in a washing machine in one spot, 2 degree rise as one of those eddies hits the coast doesnt surprise me.

[PinHead]

A 2C variaton is such a short time does not seem possible...laws of thermodynamics dictates that the heat will disperse into an object of less heat thus giving a common temp..with the massise volumes of water involved I cannot see how anything could achieve that result in such a short time.

[ProFleet]

I agree with Poindexter......
