Sure, San Diego is better, but "rubbish"? It makes me think these people have never lived in a places like Montana, Nebraska etc. where if you aren't soaked with sweat and covered in mosquito bites your face is stinging because of the biting cold. In locales with bad weather you are comfortable maybe 3-4 months out of the year, in places with good weather you are comfortable with little accommodation, e.g. AC, heating, clothing, for most of the year; San Francisco has demonstrably okay weather, it is boring and not "perfect" but far from rubbish.
