Gorgeous pictures!! I am frightened whenever I have to drive in fog.

I am too, Janey! I drive over a mountain frequently, and it can be a real challenge in foggy conditions. White knuckles.

Beautiful photo's .....but doesn't look like the city I grew up in.....and have not returned to in ages. I can feel the chill....that I didn't feel back then, interestingly. A lifetime ago.

We live on Twin Peaks which is one of the foggiest parts of the city. Sometimes we're in the sun and the fog is laid out below us. Some parts of the city never get the fog. Some people think the fog is romantic. Personally I find it depressing. Not to be picky, but it's referred to

locally as the "marine layer". Supposedly there is a difference, but I've always called it fog.Beautiful pictures.

Beautiful photos. Driving in fog is normal here in Newfoundland. I remember one January we were in Ottawa, driving to Montebello, an hour away, in Quebec, to a company Christmas party. It was a little bit foggy on the way. When we got there other people were talking about how foggy it was and how hard it was to drive in it. Compared to Newfoundland it didn't seem very foggy at all!

Marine layer refers to how the fog forms along the coast, just as tule (too-lee) fog is the term used in California for inland valley fog caused by a temperature drop of air with high relative humidity. (Tules are reeds that grow in inland marshes). This is also the typical cause of fog in other inland areas.

Fog is fog no matter what the cause. It's air that has such high relative humidity that it's almost at full capacity for how much water it can hold. Visible water vapor results. Just like a ground hugging cloud, same thing. Or the cloud you fly through in an airplane. Same effect, same appearance when you're in it.

Yeah - fog pretty well equals cloud ... depending on the location ... or, more accurately, altitude.

I work in the City and live in Marin county. One day driving home, I passed (on the bridge!) from BLACK clouds to fog POURING into the bay to BRIGHT sunshine! I had a double decker tour bus right next to me and thought this was a wonderful treat for the tourists (for me too)! The GGB is not very long, and to see all of that in less than a mile was really something. I should add that this is not uncommon in the Bay Area; the place is known for microclimates.

Maddie, I visited San Francisco a few years ago. One of the things I wanted to do was walk across the Golden Gate Bridge. I didn't get to do it because the bridge was pretty well shrouded in fog the entire time even though it was sunny everywhere else!

We traveled the whole coast of Oregon, California on highways 1/101 in 1997 by motorcycle. About 75% of the trip was shrouded in fog. All we saw of the Golden Gate Bridge when we crossed it was the deck a foot or so in front of us. We just followed the barely visible tail lights ahead.

We used to live close to the GG bridge. I have often driven across it and experienced the solid fog to brilliant sunshine effect. It is stunning. We used to get fog billowing up off the ocean and it would roll over us. It almost seemed sentient.

Ditto -- gorgeous photography! I really like the ones where the bridge disappears in the fog but farther up you see the end point. (But photo #4 made me a bit dizzy!) Someday I'll get to San Francisco... How long, on average, does it take to walk across the Golden Gate Bridge?

Lovely! Thanks, Alisande!

Driving at night in a tule fog is death-defying. Sometimes you can't hardly see the end of your hood. [::shudder::] We don't get much fog at all where I currently live, and I can't say I miss it.

Maddie, you reminded me of a day when I was with a friend on a high road outside of Martinez, where it was bright, clear skies and singed hillsides (must have been September-ish). From the top of the hill or transition road or whatever it was, we could see all the way to the bay and SF. There was this black smudge out thataway, and I thought it was a huge fire. She laughed and said it was San Francisco. I said I knew it was but I was talking about the black smoke. She informed me that that was the fog. I was floored. Clear all around for miles and miles in all directions and that black cloud blanketing the city.
