Things to Do in Petaluma, CA — August 2026
The hills have gone gold, the river runs cool, and the last long evenings of summer are here. From tribute nights at the Mystic to bird walks at Helen Putnam, here is your end‑of‑summer guide to Petaluma.
August in Petaluma is a month of golden light and last hurrahs. The Butter & Egg capital’s Victorian downtown stays busy with sidewalk deals and Saturday history tours, the Petaluma River keeps its cool for paddlers and strollers, and the music calendar at the 1911‑era Mystic Theatre fills up fast.
It is also a month of transitions: Summer Reading logs come due at the library, Petaluma City Schools welcome students back mid‑month, and by Labor Day weekend the town is easing into harvest season. Soak it up while the evenings are still warm.
Every listing below was verified against the organizer’s own calendar, listed in chronological order, with recurring happenings gathered at the end. Always confirm details before you go — summer schedules shift.
