Climate-controlled vs. standard storage in San Diego

San Diego, CA enjoys a mild Mediterranean climate — dry summers, wet but moderate winters. Storage here is generally low-stress on contents, which means standard (non-climate) storage is acceptable for most household goods, tools, and seasonal items. Climate control is still recommended for electronics, fine art, musical instruments, or anything you'd consider irreplaceable. Coastal air can carry a bit more salt/moisture than inland, so facilities farther from the water tend to be drier.

What to look for in a San Diego storage facility
