Beach weather really depends on what you want to do at the beach. If you want to play in the surf, then lay in the sun, then likely NO not beach weather, If you want to do daily walks on the beach (like we do every time we stay there) or just sit in the sun on a beach chair then YES the weather will likely be great for things like that.I don't know where you live, but if you are Minnesota or the east coast, you will feel as if it is the summer. In either case the weather should be at its worse in the high 60's or low 70's in the day and as low as the 40's in the evening.
However, the weather is very, very unpredictable.
