Where I am on the Southeast Coast of Vancouver Island, BC, Canada, “GOOD” Low tides happen approximately twice a month, one is usually better than the other (Lower). The summer low tides also have a couple days before and a couple days after that are usually OK too!
If you want to experience the best of a “West Coast Holiday” try planning your trip around a low tide cycle. Just look up the tide tables and see when the low tides are going to happen.
