Most summer guides to Sonoma read like they were written for someone arriving on a Friday and leaving on a Sunday. If you already live here, the calendar looks different. The Plaza has a rhythm you set your week by, and this year that rhythm is absorbing more change at once than it has in a while. Two new restaurants are opening directly on the square, the free Sunday concerts run five months instead of three, and the City Party is back for its 29th year on a Thursday in August that most residents already have blocked off.
Here is what the season actually looks like from the inside.
The Week, as Locals Run It
Before the new openings, before the festivals, the shape of a Sonoma summer week is set by three recurring events. If you keep a mental map of them, you understand ninety percent of what your neighbors are doing between June and September.
| Day | What's happening | Where | Window |
|---|---|---|---|
| Sunday | Sonoma Sundays free concerts | Grinstead Amphitheater | 2:00 to 5:00 p.m. |
| Tuesday | Tuesday Night Market | Sonoma Plaza | 5:00 to 8:00 p.m. |
| Saturday | Broadway Under the Stars | Transcendence Theater venues | Evenings, select weekends |
The Sonoma Sundays concert series at the Grinstead Amphitheater runs Sundays from 2:00 to 5:00 p.m. from June 7 through October 4, 2026, presented by Music in Place with the City of Sonoma. That is a five-month stretch, which quietly makes it one of the longest free live-music runs of any comparable California town square. The lineup carries into fall with Sascha Jacobsen & Mark St. Mary on September 6, Tyler Lauren on September 20, Robert Dehlinger's Alpha Rhythm Kings on September 27, and closes with the Sonoma Stealth Band and Joe Smiell Orchestra for Oktoberfest on October 4.
The Tuesday Night Market runs every Tuesday evening from 5 to 8 p.m., May through the end of August, on the historic Sonoma Plaza, with locally grown produce, live music, and prepared foods. It is the one weekly event that locals treat as an obligation rather than an option.
The Plaza's Dining Reshuffle
The bigger story of 2026 is what is opening on and around the Plaza. Sonoma has not had this much restaurant turnover on the square in recent memory, and both openings come from operators who already have a track record here.
SMASH. Ari Weiswasser, chef and proprietor of Stella and Glen Ellen Star, is opening a fast-casual burger and fried chicken restaurant called SMASH on the Sonoma Plaza. From the Stella and Glen Ellen Star team, this fast-casual spot near the Sonoma Plaza will serve smashburgers, fried chicken sandwiches, fries, shakes and cocktails, including a few boozy ones. The pivot from Weiswasser's higher-end kitchens down to a counter-service burger is worth paying attention to. It is a bet that the Plaza needs a place that works on a Tuesday after the market as easily as it works for a family lunch on a Saturday.
Dead Letter. Dead Letter, a live-fire kitchen concept from the girl & the fig team, is opening at the former Maya Restaurant space in Sonoma. Chef John Toulze of the girl & the fig will run the kitchen. The Maya space had been a fixture for years, and handing it to Toulze rather than to an outside group is the kind of move that keeps the Plaza's food identity coherent even as it changes.
Read the two openings together and a pattern emerges. Sonoma's dining scene is not importing new operators from San Francisco or Napa this year. It is deepening the bench of restaurateurs who already live and cook here. That matters if you own a home nearby, because it means the Plaza's evolution is being underwritten by people with a reason to stay.

The One Night Everyone Shows Up
If there is a single evening that separates residents from visitors, it is the first Thursday in August.
The 29th Annual Sonoma City Party is on Thursday, August 6, 2026, at the historic Sonoma Plaza, with food and beverage vendors serving from 5:00 p.m. and live music from 6:00 to 9:30 p.m. This year's entertainment features Maya from 6:00 to 7:00 p.m. and Neon Velvet from 7:30 to 9:30 p.m. Free Bike Valet service, provided by Operation Bicycle, will be available, and guests who arrive by bicycle receive a $1 Bike Buck redeemable with participating food vendors while supplies last.
The Bike Valet detail is a small thing that says a lot about who this event is designed for. It is not built for the drive-in crowd. It is built for the person who lives close enough to pedal in, and it rewards them with a dollar toward dinner. Twenty-nine years of doing this has produced a party that assumes you are a neighbor first.
Beyond the Square
The Plaza gets most of the attention, but the summer rhythm expands well past its four sides.
- Broadway Under the Stars. Transcendence Theater Company's lineup includes "Ain't Too Proud to Beg," "Radio Recall," and "Mamma Mia!" for its 15th season. The company's outdoor performances have become a summer institution in Jack London State Historic Park, and a fifteenth season is not a milestone you reach by accident.
- Gay Wine Weekend. Gay Wine Weekend returns to Sonoma Valley July 17 through 19, 2026 for a 15th Anniversary celebration. Locally rooted, quietly influential, and the kind of weekend a lot of wine country regulars plan their July around.
- Lavender Bloom Fest at Bees N Blooms. The festival runs May 23 through July 12 on Saturdays and Sundays from 10 a.m. to 4 p.m., with additional evening hours on May 29 and every Friday in June from 6 to 9 p.m. Reservations are required, guests can enjoy self-guided farm access, a Lavender Labyrinth walk, and seasonal blooms, and select evenings feature live jazz. A short drive south for anyone who wants a Saturday morning that does not involve tasting rooms.
- NASCAR at Sonoma Raceway. June features NASCAR Race Weekend at Sonoma Raceway, including the Toyota/Save Mart 350, along with Bear Flag Weekend. Locals plan for the traffic the way people in San Francisco plan for a Giants homestand.
Something else worth mentioning quietly: on Saturday, July 18, 2026 from 1:00 to 2:00 p.m., the Sonoma Hometown Band plays a free "Picnic in the Plaza" at the Grinstead Amphitheater on the Sonoma Plaza. The kind of one-hour community concert that is not advertised much because it does not need to be.
Why the Reshuffle Matters if You Own Here
The interesting thing about this summer is not any single opening or event. It is that the Plaza is absorbing meaningful change without losing its shape. The concert series is on the same amphitheater it has always used. The market runs the same hours it has for years. The City Party is on the first Thursday in August, again. What is shifting is the retail and restaurant mix around that fixed civic backbone.
In one of the busiest opening seasons in recent years, more than 20 restaurants have opened or are slated to debut in Sonoma County in 2026, and some restaurateurs point to a softening real estate market and easing rents as one reason behind the surge. That is a countywide read, but it matches what is happening on the Plaza specifically. The operators moving into visible corner spaces are experienced locals, not out-of-market bets, and the leasing environment is finally letting them make the move.
For anyone who bought a home here in the last few years, this is the version of neighborhood change you actually want. The character of the square is being reinforced by the same people who built it. For anyone considering a move, the summer calendar is the best possible tour. You do not need a real estate agent to walk the Plaza on a Sunday afternoon in July. You need a lawn chair.
A Short List for the Next Ninety Days
- Sunday afternoons at the Grinstead Amphitheater, through October 4
- Tuesday evenings at the market through the end of August
- SMASH and Dead Letter, worth a visit as soon as they open
- Thursday, August 6 blocked off for the City Party
- One Saturday morning at the Lavender Labyrinth before July 12
- Any Transcendence performance you can get seats for
That is the season, from the inside.
