* Tides are caused by the Moon's (and Sun's) gravitational pull: The Moon's gravity pulls on the Earth's oceans, creating bulges of water on the side of the Earth facing the Moon and the opposite side. This is why we have high tides. The Sun also exerts a gravitational pull, but it's weaker because it's much farther away.
* The Moon's position doesn't matter for tides: Whether the Moon is visible in the sky or not, its gravitational pull is still affecting the Earth's oceans. The Moon's position in its orbit around Earth influences the timing and strength of tides, but not their existence.
Think of it like this: You can't see the force of gravity, but it's still acting on you all the time. The same applies to the Moon's gravitational pull on the oceans.
So, even though the Moon might not be visible in the morning, its gravity is still pulling on the Earth's oceans, causing the tides.
