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,

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.
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
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.
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.
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.
