Why go now
$217 per person round trip, nonstop, is exactly the median of 11 earlier checks we ran on this route. That makes it a fair price, not a markdown, and the lowest we've seen was $104, on Oct 12. The real reason to go is the timing. September and October bring San Francisco's warmest, clearest weather of the year, and the forecast agrees: 70°F and partly cloudy on Friday, 78°F and clear on Saturday, 81°F and mostly clear on Sunday, with rain chances of 6% or less. Fleet Week also falls in October. You leave Friday at 3:14 PM and you're back in San Diego by 1:16 PM Sunday. All three hotels we found offer free cancellation. Prices are all-in as found when we checked, and they can change.
The kind of trip this is
This is a city weekend with food and a bit of nature on the side: cable cars, dim sum in Chinatown, burritos in the Mission and a walk over the Golden Gate Bridge. It suits a couple or two friends who like to walk, since the city is compact and hilly. You arrive Friday evening, so you get one full Saturday and a Sunday morning. Pick a few things and take your time with them.
