Like a thoughtful friend, the Delta Breeze often shows up right when it’s needed. … Because of that, any potential threats to the breeze are taken seriously. When word got around that the billionaire-backed California Forever development — which could add thousands of new homes and a shipyard in Solano County — might disrupt the breeze, residents were concerned. … Experts from the National Weather Service office in Sacramento and UC Davis said the phenomenon, often manifesting as a gentle cooling trend, is driven by atmospheric forces that occur over hundreds of miles. Because of that, a surface level development, even one as potentially large as California Forever, likely will not have a noticeable effect on the breeze.
