Tides are caused by the gravitational forces of the moon and the sun, and most coastal areas experience two high tides and two low tides every lunar day (which is about 24 hours and 50 minutes).
If you are at the beach for 24 hours, you can generally expect to experience:
- 2 high tides
- 2 low tides
So during your 24-hour camping period from 8:00 AM to 8:00 AM the following day, you would typically experience 2 high tides and 2 low tides.
