I've recently become a little obsessed with the weather effects on fishing. I go out in all weather types and situations but i've recently started to document moon phase and barometric pressure. I will say the moon phases are spot on. Full moon and new moon seems to produce the best amount of action for me. You can probably get 2 or 3 days of a full and new moon. Also barometric pressure seems to be pretty accurate as well. Now if I can just get a moon phase and a raising or falling pressure to coincide it'll be like the perfect storm ha ha.
