Excerpt from my latest Sasstrology article (please leave comments on the Sasstrology site):
"The solar return chart is a forecasting technique that offers an overall view of one year. It doesn’t focus on specific transits or timing (although there are a couple of timing indicators that can be used) but it does provide a snapshot of events. One event that it is fairly reliable at predicting is a new relationship, as well as what that relationship may be like."
