Summer in San Francisco means exactly two things: pretending 58 degrees is warm and arguing about which free outdoor music lineup is better. This year, Stern Grove and SF Bay Popfest are both making strong cases for getting you off the couch.

Stern Grove's annual free concert series — one of the last genuinely great civic traditions in a city that keeps finding new ways to spend your money on things nobody asked for — is back with another season of Sunday performances in one of the most beautiful natural amphitheaters on the West Coast. It's free, it's outdoors, and it doesn't require navigating a single city bureaucracy to enjoy. Imagine that.

Meanwhile, SF Bay Popfest is doing its thing for the indie crowd, curating a lineup that reportedly includes "lesbian doom folk" as a genre descriptor. And honestly? We're here for it. Say what you will about San Francisco's cultural scene — and we say plenty — but this is the kind of weird, wonderful specificity that makes the city worth living in despite the $4,000 rent and the supervisors who think they know better than you how to spend your paycheck.

Here's what's worth celebrating: both of these events represent the kind of community-driven culture that thrives without massive government subsidies or a task force to study whether music is equitable. Stern Grove has been running its free concert series since 1938 — nearly nine decades of private philanthropy and community support doing what city programs routinely fail to accomplish.

So mark your calendars. Grab a blanket, a jacket (it's still San Francisco), and enjoy the rare civic experience that doesn't come with a line item on your tax bill. Summer's short here, and the lineups are long. Don't overthink it — just show up.
