I can't recall a single day this year during which we've had what you've described. Certainly the "more often than real fog" statement is completely false.
Do you doubt there's been smoggy air here in SF, which you can see due to particulate matter from the wildfires? This happens often. I mean it's basically just slightly thicker than normal smog. And there have been many fires. It's an unremarkable, common occurrence in the Bay Area today, this smog that is made worse by fires.
When it's moist out - not enough for real fog, mind you - it can pass for a fake fog.
Due to the heat, there's also been much less real fog.
So all I'm saying is that there have been more days w/visible smog than fog in SF in 2022. Which I stand by, as something I've observed, which is also something you'd expect, given 1) number of fires increasing smog and 2) heat wave decreasing real fog.
I'd say we see this type of "fog" more often than real fog in SF today.
