Visit The Beach During Off-Hours/Off-Season
This is a bit contradictory to one of my earlier points, but I highly recommend trying to visit the beach at times when there won’t be a lot of people around. I enjoy taking photos of the beach at sunset, but a lot of locals and tourists in Los Angeles will usually stay for the sunset (especially during the summer) as well. Unless you don’t mind removing people in post, then visiting the beach at less busy times might be a huge benefit for you.
I am able to find some locations that are less busy during this time, but I feel I have a lot of more creativity in capturing beach landscapes without distractions when I visit the beach early in the morning, or capture sunsets during the fall or winter, when people are less likely to go to the beach when it’s much colder.
Most of my favorite beach travel photos are actually taken during the end of the year, when sunset comes earlier in the evening and most people aren’t around.
