I’ve had excellent nights up there weeks before and weeks after the full moon. I don’t think the amount of available moon light is as important as the weather. This is based on a LOT of night time up there over the last 6 – 7 years. If you get a hard cold front and a calm night to fall on the night of the full moon things are going to be tough. Get a good storm front blowing through 10 days before the full moon and you’ll have a heck fo a good night. Targeting your trips around the full moon is just playing the percentages. A guy can’t count on the weather but we do know when that full moon will show up each month. If I could only fish one night a month and I had to choose early I’d opt for the full moon and be comfortable doing so.
Last fall I took Mudlnthru up for a couple nights, one of which was WAY in advance of the full moon. It was windy, rainy and miserable but the fish were just going nutz. There was no moon light with the clouds hanging very thick and very low. Combine that with rain and it was as black dark as the bottom of a well…. but the fish were slamming.
On dark night you usually need to fish a little bigger, slower and something with rattles. If they’re feeding they can definitely find it.
