Hey welcome to Brainly. :)
One thing that is the most obvious and known to everyone is the moons gravitational pull. But another one some people fail to mention is that the sun also plays a part in the making of tides.
An interesting thing is that winds and weather affect the tides level. If the wind is fierce it can push the water away from the coast and affect the tide.
The next but most unknown to us is the actual coast. Depending on the size of the coast or shore, (you may know this as the beach), determines the range the tide is able to push up. Smaller shores tend to have a higher tide.
Hope I was able to help. :) Have a nice day.
