Every late spring and early summer I break out in an itchy rash only where the sun hits me, why is this and what is it called?

In brief: The most common...

Cause is something called polymorphous light eruption (pmle), and it is basically your skin reacting to light in the ultraviolet and visible spectrums for unknown reasons.
Other things can cause rashes in sun-exposed areas, such as certain medications, and a disease called lupus. If the problem is significant, see a dermatologist, particularly if you have other symptoms like sore joints.

In brief: PLE

This is called polymorphic light eruption; there is little to do about this.
Topical steroid creams can help bring the rash under control, but the only way to prevent it is to avoid sun exposure with wide-brimmed hats and loose-fitting, long sleeves. Most people just use the creams to tough it through the first few weeks; then they're able to enjoy the sun for the rest of the summer.
