We were successful! We also started a trend. There was one small family at this beach when we arrived and by the time we left there were several more groups.
…the sign said no swimming.
After dipping our toes in and checking it out, I agreed with the signage. There was quite an undercurrent, especially with the storm coming but it was okay to wade in waist deep and have a quick dunk.
We set up our towels and had a tan. This would be our compromise and it was better than getting back on a train and heading off to another beach which may or may not let us swim.
