Weather

I really like the winter here. It isn't cold, but is refreshing and I prefer cold weather to hot.
I have never seen snow, but I live near to a mountain that has snow in January and sometimes February too. The weather here is so hot, I mean, like 18°C here is cold and everyone wears warm clothes when the temperature decreases like that. It can heat up to 35°C in summer and the air gets dry but it doesn't look like a desert here. There are many trees but almost all of them are dry.
From May until September it is the rainy season and all the land gets green, the rivers get water, and some people grown corn or other grains.

But rain season is also dangerous here beacause there are many thunder storms with thundering and lightnings. Actually, last year a man died because he was working in the afternoon on his ranch and a lightning hit him. He died immediately.

Very good! One difference is that in English we tend not to say, "This and that and the other and so on." but, "This, that, the other, and so on." ;)

A good post!  Try not to begin any sentences with "and" or "but" as that is poor English. Keep up your good work!
