I live on the very northwest tip of Washington State.  I am used to fishing in extreme weather conditions when it is usually 100+ in the summer and in the negatives in the winter.  Here on the coast, it usually stays in the 40s in the winter and we dont have many 80 degree days in the summer.  How will the bass react to this?  Do they still go deep or just stay up year round?  

Interesting question. My thoughts (guesses):

-Bass without A LOT of food (or a real good hunting advantage/opportunity) begin to reduce activity in water over 80+F.

-From anglers I've chatted with, bass in the far north (CN) where water temps just don't break 80, seem not to suffer this mid-summer doldrums.

-In my experience bass (LM and SM) have a tendency to move away from shore in summer. This is true even in shallow waters (<10feet). There are exceptions -waters that will maintain good shoreline bass fishing through summer (lotsa shoreline cover and food). But moving away from shore is a strong tendency I see. In my shallow ponds I believe the reasons are twofold: fishing pressure and the fact that the big 'gills (that mature bass target) move away from shore to feed.

In larger deeper waters, bass may expand deeper into cooler waters -likely following a food resource coupled with appropriate temperatures.

Ralph Manns has mused (not proven) that this could be habitual, due to the fact that in many waters (coverless res. is my guess) fry move away from shore to graze zooplankton, and this tendency holds in many bass as they mature.

-Although there are historical constraints, bass populations develop their own specific habits and can adapt to specific conditions over time. This is something to keep in the back of your mind when trying to "pigeonhole" anything biological. There is a hole, and don't expect to cram a square peg into it. But that hole can vary.

So...enjoy the stability. Get to know your new waters.

And then come back and tell us what you've found. 8-)
