If San Francisco is so drippy that Lombard Street is starting to look like Niagara Falls and your vacation plans are sinking faster than the Titanic, here's the first thing to do. Run outside and sing like the Eurythmics: 'Here Comes the Rain Again" - or if you're looking for love, substitute a hope-filled version of "It's Raining Men."
After that, check the local weather forecast to see if a change of location might help.
When it's raining in San Francisco, it may be clear in Monterey and Carmel, or Napa.
If the rain of terror won't let up, you could complain to the mayor, but a more practical action is to find something to do indoors. You can find a museum for almost any interest, and they're all in the San Francisco Museum Guide. Museums always get busier on rainy days, but you can avoid that long line at the ticket counter by ordering your tickets online before you go.
You could also browse the list of indoor day trips. If it's raining so hard that you worry you'll get washed away, head to the library to look up how to build an ark.
If you packed your fancypants Wellies, now is the time to put them on. With just a bit of rain gear, you have more options. If you don't have an umbrella, you won't have to walk far to find one. Enterprising umbrella-sellers pop up everywhere just as the first raindrops hit the pavement.
Now that you're properly attired try these ways to defeat the damp on a rainy day in San Francisco.
- Go on a Pub Crawl - Visit one or two of San Francisco's microbreweries. Use a designated driver, take public transportation or call a taxi.
- Irish Coffee at Buena Vista Cafe - The first place in America to serve this warm, alcoholic concoction is still going strong, and all that hot coffee and alcohol are pitch-perfect for a rainy day.
- Let Someone Else Do the Driving: You might need to plan ahead - just a little - but why not stay dry and see the city at the same time in a classic VW van with Vantigo?
- Play Games: Musee Mecanique at Fisherman's Wharf is packed full of antique arcade games, some of them more than a century old. It appeals to all ages, including the most video-game-addicted kids. Change machines are plentiful, and a few dollars can keep everyone busy for quite a while.
- Go on an Indoor Tour - San Francisco City Guides offers some fun guided tours that stay inside. You can go behind the scenes at the Palace Hotel, see the upstairs murals at Coit Tower, or visit the San Francisco Fire Department Museum.
- Browse for Books - The concept may seem a little old-fashioned if you're doing all your reading on a mobile device these days, but City Lights Bookstore in North Beach is a real book lover's bookstore. Stop next door at Vesuvio Cafe, a remainder of the Beat era.
- Take Some Photos - It's not as crazy as it sounds. Rainy days can offer the photographer some interesting shots, like the one here of the Golden Gate Bridge. Try a black-and-white photo of the skyline from the end of Pier 7. Focus on details. Look for reflections in puddles.
- Learn How Things are Made - Just across the Bay Bridge in Berkeley, you can learn how sake is made at Takara Sake. A drive north takes you to the Jelly Belly Factory. Or stay in San Francisco and take the Boudin Bakery tour.
