No, the moon has no effect on how much you weigh at any time of day or night. Even if it does, hunch down a few of inches and you'll be fully free of its gravity. Furthermore, half of the time the moon is visible is during the day, but you haven't noticed. Finally, the weight of the ocean is not responsible for tides; instead, it's the gravitational pull of the sun and moon that causes them.
The moon does have an effect on surface water levels and this is what causes tides. As the moon passes over a region of sea floor, it creates a low point and high point in the water above it. This occurs whether there are mountains to stop the flow of water under the surface or not. The size of these dips can be large enough to cover shoreline roads and destroy boats if they're not careful.
However, these effects are perfectly normal and happen every day. They have nothing to do with any extra weight you might be carrying.
The moon's influence on the oceans takes place because the water tries to return to its original position which is higher than where the moon is located. This means that there is less pressure on one side of the ocean and more pressure on the other. It makes sense that this would cause some seasides to rise up high enough to block access but this isn't due to any extra weight you might be carrying around.
The gravity of the Moon is one-sixth that of the Earth. So, if you want to know how much you'd weigh on the Moon, split your current weight by 6. However, mass and weight are not the same thing. On the Moon, your mass, or the amount of substance that makes up your makeup, will not change. Only the gravitational force acting on you will change. This will make it harder for you to resist the forces of gravity from other objects on the Moon - such as those around planets. The more massive they are, the more influence they will have on your own mass.
The Moon affects the tides, and high tides occur when the Moon is full or new. Low tides happen when the Moon is waning or old.
People have been aware of the relationship between the Moon's cycle and the sea for thousands of years. Ancient sailors used this knowledge to guide their ships at sea. They believed that if they sailed towards the setting Sun they would be able to find safe waters, but that there would be dangerous seas if they turned away from it.
It may sound like a lot of fun to lose a little weight every time the moon passes over you, but bear in mind tides. Gravity's pull weakens with distance. The distant side of the Earth, for example, now feels less gravity from the Moon than the side facing it. As a result, the far side of the Earth weighs more than the near side.
This effect is called "gravitational self-weight". It's what causes objects to sink to the bottom of a lake or ocean, for example. Without this force, there would be no reason for ships to float or fish to swim upward toward the surface of the water.
Gravity also decreases as you get farther away from a massive body (such as the Sun). Because of this, any object in orbit around another body will eventually fall back to Earth due to gravity's own effects.
The Moon's influence on the Earth's oceans is what makes gravity decrease as an object gets farther away. If the Moon were not present, then gravity would remain constant regardless of distance. This means that any object in lunar orbit would never fall back to Earth because there would be nowhere for it to go.
Of course, we don't want anything in lunar orbit because that would be very dangerous. If a rocket crashed into the Moon, for example, its fuel might cause global warming or pollute the environment.
Because of differences in gravity strength on the moon, our weight on the moon is less than it would be on Earth. The gravitational pull of the moon is influenced by its mass and size. This indicates that if you travelled to the moon, you'd weigh less even if your mass remained same! The moon's mass is about one-thirteenth that of Earth, so its effect on us is negligible.
As we know, water weighs more when it's warm than when it's cold. On the moon, all objects (including water) are affected by this phenomenon because the heat from the sun causes the ice on top of the lunar mountains to melt, producing clouds of vapor that stream into space where they eventually form stars or galaxy clusters. The remaining rock and soil beneath these clouds of vapor becomes exposed to the solar radiation, which causes it to heat up and evaporate as well. So all the water on the moon is lost within a few hundred years after the end of the last ice age.
During this period, the amount of energy coming from the sun was lower than today, so there was less heating to resist inside habitats built by humans. This may have given people enough time to move some of their water away from the places where it could be seen, perhaps using small vehicles. Or maybe they used some kind of magic spell to make some of it disappear? We can't say for sure because no one has ever been to the moon!
