On our first day in San Diego, we went to the beach in La Jolla. It was only around 60 degrees F and pretty windy. My daughter, Eleanor, didn't seem to mind because, once she got in the water she did not want to come out. We spent a couple of hours playing in the ocean and in the sand.
When we were done playing we walked over to the pier where you can view dozens of sea lions soaking up the sun.
You can walk out on the walkway that will lead you out into the ocean and get a good view of the sea lions and the water.
