One of my most magical bike rides was along Skyline Boulevard on the coast range on the SF Peninsula. It was a summer day as the fog moved in; there was a moderate wind out of the west, pushing clouds from west to east.
In the less densely-forested areas, it was windy and cold, but every time we went through a patch of trees, the wind died down, and it was raining. The way the trees caught the blowing fog meant it was more than the drips you get off of trees some days, but it felt like actual, natural rain. And I imagine on some level it's difficult to truly parse out the difference between which droplets came from fog hitting tree branches, and which were forced out of the cloud by the slowing and densifying moist air as it hit a thick grove of trees.
I realize this is pretty subjective, but there is not a single time that I have appreciated being in the fog on a bike ride or hike. It can be pretty to watch rolling in over the hills, but once I am in it, I always feel cold and miserable. I'd almost prefer that it just rain, because at least then I would have a valid excuse to stay home.
It's been a few years, so my memory might be rosier than the experience was at the time. I grew up in the PNW and it was a solid 10 years in the Bay Area before I could actually appreciate rain again. And I still hate it when bad weather ruins my plans.
However, one of my favorite scenic things here on the Peninsula is watching the clouds/fog crash over the coast range every afternoon in the summer. From a safe distance in my 70 degree neighborhood, of course.
I had a similar experience biking on Mnt Tam. It was pretty amazing. I also recall it being pretty hot and sunny on the way up and the way down and it only being cold, foggy and wet at the very top. The contrast made even more magical.
