Hi mate,
Here in New Zealand winter is actually a good time for trout fishing near river mouths. Winter is the time when they move up rivers after heavy rain for spawning. Lakes are also fishing well during winter as trout tend to rise closer to the surface in the cooler weather.
It might be different in you area though.
Where are you from?
Cheers
Mark
If people concentrated on the really important things in life, there'd be a shortage of fishing poles.
