Beautiful, Blue Angel

I am cold and chill even during peak summer.
In the silence of night I am louder than a murmur.
Being beautiful and pristine, I am loved by young and old.
Reaching the shore, my exhausted waves unfold.
Their white foamy lather touches my shore and sand.
Deep blue body with a white lacey edge does look grand.
Ups and downs of my waves displace and shake the swimmers-at-ease.
There is slight panic in the eyes when water rises above the knees.
When it touches the bust, warnings and screams ring in the air.
Sometimes, spanking by the waves is unable to bear!!
They hit so hard that exclamations are of highest octave!
Drenched from head to toe are the screamers by a single humongous wave!
Giggles and laughter echo when feet gradually slip in to sand pit.
Noisy admiration happens when sun and I meet!!!
That amazing illusionary scene all mouths greet.
Boats and ships too disturb my tranquility and peace.
I keep calm and cool, forever saying cheese!!!!
My serenity is often compared to divinity!
My roughness invokes the devil in me, causing a calamity!!
This evil hidden inside me, the angel, one and all know.
Yet, coming to my beach all faces glow!!!!!
