Can you explain this sonnet 18 by shakespeare?

Question

in your own understanding..

Shall I compare thee to a summer's day?

Thou art more lovely and more temperate:

Rough winds do shake the darling buds of May,

And summer's lease hath all too short a date:

Sometime too hot the eye of heaven shines,

And often is his gold complexion dimm'd;

And every fair from fair sometime declines,

By chance or nature's changing course untrimm'd;

But thy eternal summer shall not fade

Nor lose possession of that fair thou owest;

Nor shall Death brag thou wander'st in his shade,

When in eternal lines to time thou growest:

So long as men can breathe or eyes can see,

So long lives this and this gives life to thee.

Answer 1

The speaker is comparing his love (to a woman) to a summer's day.

Each line shows the comparison, and the couplet at the end finalizes  the thoughts.  

Now, read each line and see how you  could compare it to love -- sometimes smooth, sometimes fades, sometimes it is very short, etc.

Answer 2

Do you want me to compare you to a day in Summer?

You are more lovely and calm than a summer day.

Unlike the seasons which suffer from rough winds,

too hot sun, and short lives you will live forever.

And you will remain untouched by nature, or death

so long as men can breathe and see.
