Even dramatic differences in tide wont effect your weight because the sea level pressure doesnt change when your local tide goes out or in. So tides, in and of themself, will not have a notable effect, it would be exactly the same.
There are however two local effects that will play a role, but both of which will be fairly minimal..
1) the moon being overhead vs underfoot (which effects the tide). This will increase or decrease gravity. But two things about this. first off, the relative change in weight from atmospheric to vacuum would, relatively, be the same. That is any increase you'd see would be proportional in both settings, as would and decrease. Two the effect is too minimal to really count. The moons gravity is approximately one one millionth that of earth's on the surface of earth. So any effect would be trivial.
2) changes in local air pressure. This one is probably the only one that could have a noticeable effect. It is also the only one that would effect the relative difference between atmospheric weight and vacuum weight.
