Follow-up to Robbbbb’s post on San Francisco -
Actually, not only did SF start on the bay side, it was more than “a few decades” before SF moved west; the coast side was wind-swept sand dunes until the building of Golden Gate Park in the early part of this century, and housing out there was rare until the post-war years (that’s why all the houses look the same out there). There were tourist areas on the coast (Sutro Baths, Cliff House, and an amusement park on Ocean Beach), but no one lived out there for quite some time. Granted, part of it was the fact that the entire coast is silty, and not the best kind of building soil, for at least a half-mile inland, but having lived on the beach (actually, only one berm away from it, the only thing keeping the ocean at bay most times) for five years, I can confirm that living on the side of the peninsula protected from the ocean is preferable.
Which brings me to my own speculation. The Pacific Ocean, especially along the West Coast from about Monterey north, is inhospitable to long-term living. We don’t get hurricanes, but it’s generally cold (rarely gets above 65 degrees), windy, foggy, gray, and wet. The kind of wet that sinks into a person’s skin. Add to that that the coastline is rocky, unlike the East Coast, and exposed (thus not granting a lot of shelter from said nasty weather), and you wind up with very few areas on the coast that people would want to live in on a long-term basis.
Finally, as pointed out, coastal cities are relatively rare, and mostly come about from growth around an inlet or bay. In the U.S., most “coastal” cities are that way - New York, Boston, Providence, Philadelphia, Yorktown, Jamestown, Jacksonville. The only one I can think of running down the coast is Miami, which is one of the calmest oceans on record (not counting the occasional hurricane). Internationally, only a few cities are true “beach towns.” Lisbon, perhaps, but I’m drawing a blank on any others.
FWIW.
