Here's a satellite image of how it rolls in overnight, fills the bay, gets over some of the hills.
Below: Taken at Marin Headlands, looking SW.
The fog can't quite get over the 1000 ft. hills, but it can sneak in at sea level,
the Golden Gate is to the left.
A few days it backed off, we got some nice relief.
It almost looked like it might rain... but no such luck.
Weather out west is largely tied to elevation, and it's effect
on whatever is coming in off the ocean.
Hills and mountains squeeze the air mass.
It snows at higher elevation, it rains lower down.
The peaks of mountains surrounding Death Valley are always snow covered.
At the bottom of the valley, it can be hotter than hell. Literally.
Shot from Dante's view, looking NW at sunrise.
But not always - there' been a very persistent hi pressure system
in the four corners area, when it expands westward,
the natural air conditioning of fog stops working. Like now:
What will fall bring us? Ocean currents creating fog start to shift, fog backs off, September
and October can be the hottest months here at the coast.
I'll be sittin' here in front of my Mac, in boxer shorts,
Canon Powershot at the ready.
Who knows what tomorrow may bring?!
