The Earth tilts, and that tilt changes over the year. This means that the latitude where the sun is shining directly shifts over the course of the year. It goes from 23.5 degrees latitude in the North to 23.5 degrees latitude in the South. So the time of the year when your latitude is pointed directly at the sun is the time of the year when you are going to get the most solar energy, and your hottest day/month will come soon after.
