Hi Williams:
Here is my clumsy attempt to correct your english.  Your writing is well thought out and is expressive (easy to understand and visualize).  The mistakes are more technical than absolute grammatical errors.  Using capital letters to start a sentence and correct use of periods instead of a comma.  One lesson I have learned over and over again under editor's red pen is to use "-ing" as sparingly as possible.  When you remove the "-ing" It shortens the words and makes them more active, in the here and now. 

Here are my edits (PS I am not an English teacher, so my corrections may not be complete):

Soaking up the sun.

Summer is coming and it delights me.  At sunrise every morning I go to exercise at the public park.  I can also swim in the sea and play with sea waves.  When I feel tired I lay on the soft sand and soak up the sun.  How enjoyable!  Summer brings me energy and happiness.
