Since others have already corrected everything. I'll just explain why the first line, "August almost came to an end but it's still so hot everyday.", is incorrect.

When you say something or someone "almost came", you imply that the event did not happen and the time the event should have happenned has passed. Thus, it sounds like you are saying, August nearly ended, but did not, for some reason.

When you change "almost came" (past tense) to "has almost come" (future tense), than it is clear that the event will take place in the future, and we don't have to worry about time stopping or going backwards. :)
