ofc depends on how intense the storms going to be but the beach - any type of beach - is usually completely empty at the advent of rainfall. bring a solid rain jacket and listen to the waves and watch the clouds and make sure u inhale deeply. yes it's a bit dangerous to be outside when it's storming but so is driving a car so!
go in the water, come back to the shore, sit under an umbrella and read your book while you listen to the sound of the sea crashing onto the shore
and repeat.
