Hi,
There is truth in this old limerick for want of a better description....
Wind direction..
Westerly winds are warmer
Easterly winds are cold
Southerly are winds are ideally temperate
[the fish's body clock kicking in with a feeding response]
Northerly winds can be extreme..
This loosely speaking is what the limerick is based on.
Temperature-warm wind versus cold wind
Temperature and light conditions trigger feeding patterns in fish ...
A prime example of temperature difference-Salmon fishermen are more successful when the air temperature is a few degrees above the actual water temperature..When I was ghillie on the Cumbrian Eden in the early season mid January onwards I wouldn't disturb my best pools until the sun had risen fully ie:full light and the air temperature had risen by a couple of degrees.
Success was never guaranteed but the catch rate increased dramatically in relation to those who rushed down to the best lyes and started fishing at 9.00a.m Fishing those lyes at 10 o'clock normally produced the goods.
This scenario is true of all fishing's throughout the season.
Yes there is a lot of truth regarding wind direction in relation to the actual air temperature .
Yes there are exceptions to the rule..and fish can be caught in most conditions..Greater success however gained by adjusting the days fishing around the wind and temperature.
Bearing in mind that fish are extremely sensitive creatures and feel a drop in barometric pressure long before it rains !
Hope this generalisation helps...
Kindest regards
