where are you thinking about??
HI Tunny. i'm in s.e ireland.i'm starting a log or report on my catch for 2010 and would like to keep as much info as
possible in it.have most of what i think I need bar this? the sea takes longer to heat and cool and all i'm getting is adv rage temperatures
so i'm try'n to find out more detail???thank's
The M5 bouy off SE Ireland is currently showing a sea temperature of 9.7 degrees C as of 5pm today.
Struggling to find accurate inshore water temperatures, but I would imagine they might be a touch lower.
Thank's for the info." guessing " but if Itook1.5 - 2 degrees off the m5 bouy report I could be near enough????????????????
hi guys, this is a genuine question... but does sea temp really matter?? do you look at the temp on one of those sites and if its too low, you think about not going? i can see why it would matter, the fish are more lively etc ( ?? ) but if theres an abundance off food around, that would make them more lively aswell, would it not?? or does water temp bring in the food fish which in turn brings in the bass?? cheers for any replies, and sorry for maybe hijacking this thread...
I Hate Whiting,
Sea temp acts like a dimmer switch on bass fishing, high temps bass are active/aggressive. But low temps make the bass sluggish, and there fore harder (but not impossible) to catch. As Nathan, BJF, and some of the Channel Island Guys have proved. It will effect which baits are present for the bass to feed on, mackerel will have moved to deeper water, but herring hit the shore (around here anyway). In colder water, you have to make changes to the lures you use and how you fish them. If you read Nathan's latest blog entry you will see what I mean.
I believe fish metabolism is affected at both ends of the scale.

cold, fish have low metabolism, feeding cycle is narrowed to optimum time, fish stay
out of heavy current unless it benefits them or, they have little choice due to locale.

warm, metabolism increases, they need more food because of this. window of feeding widens.

too warm, fish slow down, just like us. They seek fast oxygenated water and I've found that feeding
switches to shallow water and oxygenated water that is subjected to locally lower temperatures and
fall off's from freshwater etc. Anywhere where the wind, the swell or the current activates the water is
where the fish will need to be. Metabolism is still high, motivation is lower.
Thanks for all the info!why i'm thinking about coastal tempetures is of this,going back to, it takes longer for the sea to
cool down and to heat up in comparison to land tempetures,with this prolonged cold spell i think that after a while the sea temp
should drop again,now this is where I start thinking.maybe i'm wrong but will Baitfish be in earlier because sea tempeture is down
and land and coastal temp is up therefore bring baitfish in for the warmer water and then the bass with them?????????????????????????????????????
ok cheers for that guys. makes sense!

kieth, you say that when its too warm they seek out oxygenated water, would the fish still hold here if the temp was not too warm? i dont mean like it is now but say in the summer/autumn when there isnt a heat wave and the temps are just right?

so as a rule (i know it wont always stick... they are bass afterall!), fish fast currents and places that catch surf in hot conds and then deeper marks etc when its normal temp? cheers
In very high temperatures I would look to deeper areas that have good current flow as these will be cooloer and better oxygenated, I would exspect to see bass coming inshore slightly later in the tide than normal (again following the slightly cooler water).
thank's everybody for there posts and knowledge.
As I see it fish go for deeper waters for heat?land tempetures rise as do Coastal waters.bass don't
follow cool or cold water but look for warmer water that's why they go to deeper waters in the winter.
as I was informed m5 is 9.7 so I don't expect to see much bass now,but I think and if i'm wrong please come back to me as this
is important to me this year.bass are comfortable up to 16 degrees?Land will heat coastal waters,sea waters will take longer to heat up
so I AM THINKING it's an early start for the BASS fisherman.If i'm wrong could somebody explain how it happens????????????????
A keen learner!
Don't know how accurate this is, but it does look clear and concise....... :D

"EDIT" have just compared the above (2300hrs) against Magicseaweed, and there seems to be a 2* fluctuation.. (unless i've calculated it incorrectly)
Hi Alan

Water temp does affect fish behaviour no doubt - at the moment shoreline temperature is close to 8 degrees on the SE coast and will continue to drop until late March and will only begin to rise in April from six or seven degrees. Temperatures will continue to rise until August and early September and then will start to fall again.

Combined with very low light hours and low temperatures now is a difficult time to catch bass on the SE coast with fly or lure. There is very little prevalent forage and they hunt very slowly if at all. Hence predators may remained switched off - unless - in some instances food becomes readily available and only then will bass hunt actively in low temps.

For some idea of patterns that exist as regards infuences and fishing on the SE coast take a quick look here ... -2009.html

TIGHT LINES.Alan o' Neill.
Interesting stuff...
After a week inside an office and the house over the weekend i need some fresh air and fancy going night plugging - you know when you just want to go fishing even though you know the odds aren't great.

Whats people's thoughts on fishing deep rock marks at night this time of year? I have a feeling there's prob fish about but maybe deeper down and sluggish in the cold - the shallow areas seem to be out of the picture.

If i go i'll be heading out to a deep water mark at night (kelp reefs and sand patches in 15-40ft water, not much tide close in) and in the lee of the wind.

Prob take 4-8ft diving (suspending) x-raps and try very slow twitchy retrieves. A few twitches should get the rattles going. Would it be worth trying something big and rattly like a Pencil Popper in the winter or are fish unlikely to rise to the surface when its cold?

Anything else to consider?
