If we're going by anecdotes... when I came to this city I was told thick blinding fog is a daily occurrence, but I was here a good week or two before the "real" fog came in, and while fog does come often, that honestly doesn't come often. Maybe 3 times a week. I classify "real" fog as days where I go from being able to see half of SF and even a bit of Alameda... to not seeing the houses a block down from my balcony. I'll admit it's impressive and straight up disorienting sometimes, (looking out at what was a skyline 20 minutes before and seeing nothing but grey), but if the locals' anecdotes about how often it used to happen are even somewhat accurate, it sounds like it's on the decline.
