When you're at the beach, there are some very distinct smells. You can smell the salt from the water along with the heat from the sand. My most favourite smell of all is the sweet coconut smell of sun tanning lotion that people put on themselves while they lay into the sun to basically "cook."
If you're looking for a quiet day of relaxation at the beach, I don't think that will work out too well. The beach is always really loud throughout the day. You can hear the loud motors of the boats and the waves of the water as they come crashing through to shore. You'll definitely be able to hear the laughter and the excitement of the kids of all ages as they splash around, play games, and build sandcastles.
While you're at the beach you can always get involved in some fun activities, if you aren't able to relax. You can go fishing, if you like touching the slimy scales of the fish and the soft touch of the cold water. Just make sure you don't get the rough, coarse sand in your shorts because you won't like that too much.
Overall the beach is lots of fun to go to, if you just want to get away from the busy everyday city life. If you are there early enough, you will be able to see a beautiful, bright sunrise and if you enjoy staying out on the beach until the evening, I'm sure you can catch a calming and loving sunset. After the sun has gone down for the night, you can sit in the sand and stare up at the amazing dark blue sky and bright shining
