When is hot too hot

[eotbmg]

Yesterday while fishing in the back bays of Monduran i came across a patch of water which was 32.6 degrees. I am not sure if my sounder is reading 100% correct but this temp was 3 degrees warmer than most other areas. I figured that it doesnt matter about the numbers that are sounder is displaying just the difference between warmer and colder areas. Which got me wondering when is hot, too hot. This bay has had the warm northerly wind blowing on to it for at least 8-10 days and was shallower than a meter in most parts. Last saturday we got some action out of it but not yesterday-obviously too hot. We caught fish closer to this bay in 29.5 degrees in 1 meter of water.
Your feedback is appreciated
Cheers
Ben.

G'day mate. Many years ago, I lived in Kununurra, WA and the nov/dec temps were around 42/43 C. It was staggering the way the barra went insane when a lure was chucked at them....how about 10 casts for 10 barra??
Used to go up to the Keep river and suss out the pools up around the estuary. The water temps would be about 38 C

Ben,
Your sounders are probably fine mate, I have recorded 95 degrees F here at Awoonga which equates to 35 degree's celcius.
You will find that the very top layer of the waterway is responsible for that reading.............it may be only the first one or two inches. I see this a fair bit with my sounders, the bow mount unit usually is a few degree's cooler because the transducer is 3 feet deeper on the base of the bow mount.

The best daytime session I have ever had by far was on one of those above 90 degrees F, but there was a lot more to it than just high surface temp.
Initially it wasnt that clear, but when I looked into it deeper, I found the true reason for the mayhem.
The Boyne valley had a huge downpour and there was really good waterflow coming down the Boyne River, almost tide like. The fish went mental.

Plenty of other sessions where the water temps has been around the mid 30 degree celcius have not been anywhere near productive, as you know theres more than one trigger for Barra to switch on.

I find that daytime Barra are not fussed on high water temps, esp high sun/low cloud days. Nightime is not so critical.
Experience tells me that fish will be deep during the above conditions, but shade and structure can also keep fish in shallow area's.

Fish are where you find them, there's always exceptions to the rule, and most times there is another piece to the puzzle that has combined to make the fish move to an area, and its not always logical. (to us at least)

Some shallow bays with wind blowing into them are actually colder because the wind has rolled out the warm stuff and the dense cool water has replaced it.
It can actually be handy for that to happen, if you find where the two temps converge, you will often find fish. A sort of air conditioner for them, as well as oxygen rich.

To finish, weather extremes usually make the fishing extremely hard!
Barra like comfortable, peaceful food rich environments.
Bit like us really.
Cheers

Cheers on all the info guys
Bobby-i have fished up in Kununurra and the Barra fishing on the Ord was sensational. Cant remember the water temp though we did get about 15 off one snag on shallow Haclo skin deeps.
Jason-From your response it sounds like we need a bloody good down pour to get the Boyne back to its origonal state!!! Bloody water temps-it seems like my eyes are glued to that little number on the screen looking for a warmer patch of water. I suppose that comes from doing alot of barra fishing in early to late spring when they are still in the shallow areas and the warmer areas are the go.
I think the next trip the sounder may be off after i suss the fish out weather or not they are deep ect. and maybe not rely on water temp so much and try to nail other behavioral factors.
Cheers for the input
