Doesn't usually matter since Neap tides don't have very high high tides or low low tides then there's not much water moving all day. You have to be on your game, I recommend fishing artificails very aggressively. You're trying to trigger a strike reaction not a hunger reaction. It's still possible to catch lots of fish but don't sit around for very long in one spot or do the same thing for long.
If you don't get a bite within 15min either change your retrieve speed/action, cut off and tie on something else, move, or all 3.
