I also wondered why the movie kept emphasizing that it was a hot hot day. They repeated this idea and made sure that the audience was aware of this. The reason why they might have repeated that it was a hot day is because hot is symbolic to anger. From what we saw in the movie, there is already much racism between white men and black men. This is very apparent inside the pizzeria. The man in the pizzeria saw that the pictures on the wall were all of white men and he openly said that they should put pictures of black men on it. Racism was openly acknowledged instead of quietly put into action and when black men felt that they were being put down, they tried to do something about it.
