But perhaps one of this summers most lasting legacies was its lack of sunshine. Summer 2009 goes down in the books as the cloudiest on record. Never since sunshine records began 115 years ago has a June-through-August period hosted less of the possible sunshine. Sunshine is measured in minutes and the summer's total was 42,887 of the season's possible 80,626 minutes of sun, or 53 percent of possible sunshine -- 67 percent is considered normal.
