A Day at the Beach by Mircea Vasiliu (Random House, 1978).
Seeing as it's 90 degrees here, I thought this book was appropriate for today. It's a simple story showing a family at the beach: swimming, building sandcastles, exploring tide pools, collecting shells, playing in seaweed. A nice feature is that there is a picture glossary with the names of different types of wildlife at the beach. There is also some diversity in the crowd scenes. All in all, a nice little book for summer.
