San Francisco has the oldest continually operating tidal gauge in the Americas, which has recorded the varying sea levels since 1854. Over the past 100 years, it has tracked an 8-inch rise in water level. It will continue rising, scientists say, and could rise by 1.5 feet by 2050.
Hmmm... A new magical mystery bucketlist item!
Google is my friend: From this page
The nation’s oldest tide gauge, housed in a wooden shack on a pier at Fort Point in San Francisco, recorded something unusual over the past 30 years.
And here at SF Gate, is found a photo. As well as a clarification:
A tiny, wooden white building with a red roof at the end of a pier near Crissy Field in the Presidio of San Francisco is ... the oldest continually operating tidal gauge in the Western Hemisphere. (emphasis my own.)
