mmmmmmmm an interesting subject. Rik is very well qualified to both discuss and demonstrate wind!
The only thing I would add is the duration that the wind has been blowing in. As has been said, our prevailing wind is southwest. If the weather patterns mean that your location has experienced a south westerly for some time, and there is a sudden switch to easterlies, personally I would stick to fishing where the wind had been blowing.
The only time I would change tact is in the summer where the UK is often affected by high pressures bringing in easterlies, in which case I would probably change position on the lake quite quickly. My assumption is that the fish are more mobile, plus there are more food sources entering the lake in summer and will more readily follow the wind patterns (not Riks wind pattern, which is purely local!). However, as we all know, what we should really do is stop theorizing and look for them!
Thermo clines were mentioned above by Murray. The position of thermo clines is impacted by the speed, temperature, and duration of the winds (amongst other things like through flow, sun etc etc). It was interesting that Rik said fish with your back to a north easterly in the calm waters. I cannot necessarily support this from a fishing point of view, but I am pretty sure that during winter, prevailing easterlies will cool the surface temperature quickly and that at this time the main “heat” source of the lake is actually held within the base / lake bed. Therefore it is likely that the position of the thermo cline is going to be nearer if you sit with your back to the NE wind in winter (i.e. the calmer waters mentioned by Rik). In the summer this is reversed. I will have to check my old study notes, but I am pretty sure this is correct.
By the way, a thermo cline, if you didn’t know, is an interface between hot and cold. At a climatic level the most obvious example is where the cold polar airs swing down meeting the hot tropicals and this essentially, through the transfer of energy, creates the jet stream. It is the same in a lake. You will have a temperature profile that at one point changes dramatically, and this signifies the position of the thermo cline.
Why thermo clines impact fishing……..well, I am a “L” plate fisherman so I do not really know.
So, while the blowing of food items etc is no doubt a big impact, if thermo clines and their position are a factor in fish location, then my assumption would be that you should look to analyse the impact of prevailing winds on thermo clines as well, and that it seems likely that understanding these variations and changes probably has a greater impact on your ability to catch in the winter rather than summer.
