It is true the weather specifically the barometer has a big effect on the biting of fish, it is like this:
A rising barometer (like just after a low has passed over the area) fishing is best.
Rapid up or down barometer (quick passing thunderstorm or similar event), fishing is good
Falling barometer (example: approching low weather front, first part of the fall is good, after that fishing is poor, the lower it goes the worse the fishing.
Unusually low barometer, like a hurricane, fishing is not good at all.
Hope this helps
