Photo Gallery Thirty-eight features a series of photos illustrating the typical gray, cold Spring-Summer weather San Francisco is famous for.  This weather pattern begins around the first of March and extends through the end of August when two to three months of "Indian Summer" with blue sky, sunshine and warm temperatures arrives.  Although day after day of this type of weather becomes oppressive to those living here, the respite from heat is undoubtedly appreciated by many visitors to the City.  Photo Gallery Thirty-eight was first published November 16, 2007 by City Birds.
