The earth's rotational axis is tilted 23 1/2 degrees from perpendicular to the orbit around the sun. Over the course of six months, the northern hemisphere moves between being tilted 23 1/2 degrees towards the sun to 23 1/2 degrees away from the sun.
The higher temperatures in the summertime are due to the sun's radiation striking the surface of the earth more directly when your hemisphere of the earth is tilted towards the sun.
Many believe that the Earth is "closer to the sun" in the summer time, but that isn't the case. The earth's perigee (point in orbit where it is closest to the sun) occurs in February. It is all about how directly your local ground is struck by the suns rays.

The earth is is rotated around the sun in a slanted angel. Different parts of the year, the world spins around the sun. So during the summer, June-September, the northern hemisphere will get the most sun, sunrays pointing towards the northern part of the world, so the world is on the left side of the sun. During fall and winter, the southern hemisphere will get the most sun, now the world is on the right side of the sun. The world has different rotations throughout the year. So this is why its hot/cold in unexpected days.

Actually the distance to the sun is irrelevant. If that were the case, the northern and southern hemipsheres would have summer at the same time.
SUmmer is caused by the tilt of the Earth's axis. When the axis tilts towards the sun the sun rays penetrate the atmosphere more directly causing more heating. In the winter the axis is tilting away from the sun so the sun ray's have to travel through more atmosphere and are less warming.
That is why it is summer in the southern hemisphere while it is winter in the northern hemisphere and vice versa.

The earth is tilted an average of 23 degrees on it's axis. In summer in the northern hemisphere the earth is closer to the sun. Below is a diagram that shows how the earth is closer and farther away at different times of the year.

The temperature has a relationship to the tilt of the axis of the Earth. During summer in the Northern Hemisphere, the Earth is tilted,towards the sun; therefore it is closer to the sun and the rays are warmer...

Summer is a season, astronomically defined as beginning around June 21, and ending around September 23 in the Northern Hemisphere. In the Southern Hemisphere, summer begins around December 21 and ends around March 21. Summer is defined by convention in meteorology as the whole months of June, July, and August, in the Northern Hemisphere, and the whole months of December, January, and February, in the Southern Hemisphere. It should be duly noted that the unofficial start of summer can be purely a matter of convention: in Ireland it is as early as May 1; in many countries it is considered to be June 1, while in many others it is as late as July 1. In general, seasonal changes occur earlier in coastal regions, so countries close to the oceans go for an earlier start to Summer than continental ones. Summer is commonly viewed as the season with the longest (and warmest) days of the year, in which the daylight predominates, through varying degrees.

What rocks to you people live under??? Because the Earth's axis is tilted, the Northern Hemisphere is closer to the sun in summer. Where did you go to school? HR PuffnStuff?

The northern hemisphere rotates closer to the sun, which makes summer...farther away in the winter.

because the earth's orbit around the sun is elliptical and not round, therefore during the summer is when the earth is closest to the sun, and winter when it's furthest.
