I every time smelled thatcan always smell when summer is approaching.

I wasn't really sure what this sentence meant. Something like this?

When I was a teenager and in my early twentyies, I really loved the summer season.

Twenty, twenty one, twenty two, twenty three, etc - these ages are "your twenties", because each of them is a twenty-something and there are ten of them, so plural :)

Every summer, I had bewent to somemany beaches in different areas and enjoyed swimming with friends of mine.

"had been" doesn't seem like the best tense here. You would use it if you were talking about a sequence of specific events in a story - "I had been to the beach before I went inside the house, so I was still all sandy". But here it feels more habitual.

"some" is okay but "many" seems to fit better.

Also, going the windsurfing made me so excitinged.

However, I realized that I needed to buy a car before I could buy the board, because nobody carry theies a board by their handson foot.

Matching past tense. "Before I buy" is okay but "before I could buy" is clearer, and "by their hands" is okay but "on foot" describes what you mean better, and it's a useful expression!

My younger sister and I went to a used car shop to check how much is a car and needed tothey cost and figure out which car I might be able to buy and I can drive it by myself.

This was not a well constructed sentence.

Those times, my face and body got suntanned every summer as if I was a professional surfer.
