Today was a horrible day because it was thirty-four degrees celcius and I had to travel in a bus with a broken air conditioner for two hours. Summer begins today here in Chile. Maybe thirty-four degrees isn't too hot but with a hundred percent humidity is not very fun.

Good. I cut-out the phrases about the city and re-arranged your adjectives a little to improve the flow of the words. I think that it's good practice to spell numerals in essays. Keep-up the good work! --Dan

My day

Today was a horrible day. , I had to travel by bus to a close nearby city, but the air conditioner was broken and we had to travel for two hours with in 34 celcius degrees! I'm in Chile and today the summer begins here. Maybe 34 degrees isn't too unbearable, much but, combined with a hundred percent of humidity, it is not very funny.
