7. 11 a.m. Picnic in the Park: Grab some gourmet picnic fixings at Bi-Rite Market (3639 18th St., 415-241-9760, www.biritemarket.com) and head over to palm-fringed Dolores Park (19th and Dolores streets), where expansive lawns turn into a veritable urban beach on a warm day. A fabulous new playground (www.friendsofdolorespark.org) beckons both young and old with climbing structures, a giant double-wide slide, and great views of downtown.
8. 1 p.m. See and Be Seen: Spend the afternoon among the hipsters on Valencia Street between 15th and 20th streets, and check out the string of independent boutiques lining the bike-friendly boulevard. You’ll find swingy dresses, vintage-style tees, and button-down shirts in smart prints at Density (593 Valencia St., 415-637-1435), and a cheeky collection of mermaid bait, moustaches, eye patches, and skull bracelets in the Pirate Store (826 Valencia St., 415-642-5905, www.826valencia.org), the pirate-supply retail arm of the writing-oriented nonprofit 826 Valencia. Find well-curated gems for wee ones — organic cotton onesies, creative, design-minded books from local publisher Chronicle Books — at Aldea Niños (1017 Valencia St., 415-874-9520, www.aldeaninos.com).
9. 5 p.m. Beer Tasting: At the newly-opened Abbot’s Cellar (742 Valencia St., 415-626-8700, www.abbotscellar.com, from $5.25 a glass, tasting menu and pairing $75) beer appreciation is happily elevated to the reverence normally accorded to wine. In addition to a changing selection of beers on draft, nearly three dozen beers are available by the glass in six-ounce tastings, plus more than 100 beers by the bottle. Pairings are offered every evening for seasonal dishes created in concert with local brewers.
10. 7:30 p.m. Sustainable Sushi: They’re not words that go together often, but “eco-friendly” and “sushi” coexist at Tataki South (1740 Church St., 415-282-1889, www.tatakisushibar.com), a Noe Valley sushi bar where only responsibly sourced fish is served, to delicious effect. Bright-orange slices of arctic char sashimi ($5.50 for two pieces) are fresh and gem-like; the albacore tuna ($5.50) is pole-caught in the Pacific; and the “faux-nagi” nigiri ($7), made with silky-smooth seared black cod, is so good that you’ll never miss the eel.
11. 9 a.m. Life’s a Beach: After a brisk walk along the Pacific (likely to be fog-shrouded) to watch the surfers and kiteboarders at Ocean Beach, the 4-mile stretch of sand that runs along the city’s western edge, cross over the Great Highway for breakfast and heavy-hitting Bloody Marys ($11) at the Beach Chalet (1000 Great Highway, 415-386-8439, www.beachchalet.com), a restaurant and brewpub with floor-to-ceiling views of the coast.
12. 11 a.m. Science Lessons: Head to Golden Gate Park and prepare to be amazed at the California Academy of Sciences (55 Music Concourse Drive, Golden Gate Park, 415-379-8000, www.calacademy.org, $29.95), where a dazzling array of exhibits includes a four-story rain forest, a coral reef bursting with 2,000 reef fish, and the new “Human Odyssey” display, which traces our species’ evolution with skull casts and interactive touch-screen maps.
