I think there's three separate threads right there buddy but to summarise each water will respond differently to varying conditions.
If we're talking very, very generally:
- The end of the wind is good, particularly a new wind, possibly due to oxygenation of water at the windward bank.
- Low pressure is good - because it brings with it cool conditions and nice winds (see above), feeding conditions if you will.
- Rain is ok, as it comes with low pressure weather systems (see above lol). I have noticed waters kicking right off after periods of rain, but that's just a personal observation.
However, for every water that responds as you'd expect there is a water that breaks the rules. I have seen waters change in the way they respond to conditions from year to year too. There are no hard and fast rules imo. Carp are carp and they'll do what they want to at a given time.
