Hello Lynn,
Thank you for your question about what direction to set up your raised beds.

Locate beds so that plants receive maximum sunlight and do not shade each other. Determine the north/south axis of the site and lay out the beds either in a north/south or east/west direction, not on a diagonal. When incorporating a trellis for vine crops such as cucumbers, beans, or grapes, run it east/west, and locate it at the northern end of the bed. The shortest crops can occupy the southern end.     Source: How to Construct a Raised Bed in the Garden (psu.edu)

The following two publications from the OSU Extension Service provide information on raised bed gardening, including some of the more important factors to consider when selecting a site. Here in Central Oregon, it is most important to choose a site that provides as much full sunlight as possible, ideally eight hours or longer during the growing season.
