Really confusing and unintuitive

The UI is very congested and overloaded with information. The background colors (specially blue and yellow) has white fonts that are impossible to read. The main information shown (temperature variation) throughout a DAY is quite useless. Why do I wanna know that? I’m more interested in the graphical trend for a WEEK.
