I fish both freshwater and saltwater. I have never done well after a coldfront during the summer. This has been more true for freshwater fishing. Now days, I don't even bother to fish after a coldfront and when possible reserve these miracles of nature for golf. Right before a coldfront, fishing is usually very good. I have fished right before a hurricane and that was extremely good but very foolish.
It appears folks in other states like Florida are more in-tune with barometeric pressures and moon phases. They seem to swear by it especially for snook. Folks in Virginia seem to be more dependent on the tide and wind patterns especially in the fall which are obviously very important. It may have to do with the fact that so many of our species are seasonal.
I have kept a journal describing all of these factors, but usually I clean too many fish to have time to get on the computer right away. I generally put in weather pattern for a week up to the fishing outing, wind direction, water temperature, tide, moon phase, and barometric pressure and of course the type of fish caught.
