If you have lived in Foster City through the last two Augusts, you already know the shape of the compromise. The old William E. Walker Recreation Center came down in 2024. Summer Days shrank around a fenced construction site. The Fourth went dark on fireworks. Off the Grid kept running on Wednesdays, but the amphitheater end of Leo J. Ryan Park felt more like a staging yard than a living room.
That is not the weekend you are getting this year. Leo Ryan Park has been the anchor of a rolling closure since construction on the new Community Center began in late 2024, with the old 1974 building torn down to make room. With the Topping Off ceremony on July 29, 2026, when a signed final steel beam is set atop the frame at 650 Shell Blvd., the visible work is winding down and the park is functioning as a full civic space again. That is the real story of Summer Days 2026. The carnival is the same carnival. The park around it is not.
What Is Actually Happening August 14 To 16
Foster City Summer Days runs August 14 to 16, 2026 at Leo Ryan Park, and admission is free. Tickets are required for the carnival rides. The pieces most residents will want to plan around:
| Day | Time | What |
|---|---|---|
| Friday, Aug 14 | 6 p.m. | Mercy and the Heartbeats headline the amphitheater |
| Saturday, Aug 15 | 11 a.m. to 6 p.m. | SJMADE artist and maker marketplace, food trucks by Moveable Feast |
| Saturday, Aug 15 | evening | Free concert with Tainted Love Band |
| Saturday and Sunday | all day | Rubber Ducky Scavenger Hunt, car show, craft beer garden |
| Sunday, Aug 16 | closes 5 p.m. | Event ends |
Friday, August 14, 6 p.m.: Mercy and the Heartbeats headline the amphitheater. Saturday, August 15, 11 a.m. to 6 p.m.: SJMADE curates a marketplace of more than 60 makers and artists, with food trucks placed by Moveable Feast. Saturday and Sunday: Rubber Ducky Scavenger Hunt, carnival rides ticketed separately, car show, and a Northern California craft beer garden with wine service run by local service clubs. A free Saturday evening concert with Tainted Love Band is on the community stage.
Two structural notes for anyone who has done this before. The Rubber Ducky Races are different this year because of construction. Instead of a race, it is a weekend-long Rubber Ducky Scavenger Hunt where you search for hidden ducks scattered through the event and win a prize for finding one. And Sports Basement is providing complimentary bike parking on Saturday and Sunday from 11 a.m. to 5 p.m., which is quietly the best move if you live inside the Shell Boulevard loop.
The Street Closure Actually Matters This Year
Because the construction footprint is still in place around the new Community Center, the road closure is longer and starts earlier than in a normal year. Shell Boulevard between East Hillsdale Boulevard and Foster Square Lane closes to through traffic from 9:00 AM on Tuesday, August 11 until 5:00 AM on Tuesday, August 18. Shell Boulevard between Foster Square Lane and Bounty Drive closes to through traffic from 9:00 AM on Thursday, August 13 until 5:00 AM on Monday, August 17. Balclutha Drive between the round-about on the PJCC campus and Shell Boulevard closes on the same Thursday-to-Monday window, and the Shell Boulevard exit from the PJCC campus South Service Road closes with it.
Translated to a weekly rhythm:
- If your street feeds Shell between Hillsdale and Bounty, run your grocery and airport trips Monday or early Tuesday
- If you take Balclutha to reach PJCC or the south side, plan Wednesday morning at the latest
- Event parking is not allowed in private retail centers or nearby residential streets, so if you have out-of-town family visiting, tell them to skip the drive-in-and-circle strategy
- Accessibility parking is at the Community Center and Foster City Library lot at 1000 E. Hillsdale Boulevard

Wednesdays Are The Sleeper Recommendation
The bigger change to how Leo Ryan feels this summer is not the August weekend at all. It is what happens on Wednesday nights.
Off the Grid: Foster City returned to Leo Ryan Park on Wednesday nights beginning April 1 and runs through October, offering live entertainment each week and food from the Off the Grid community in the Leo Ryan Park meadow. The format is what is new. Foster City Market offers crowd-favorite food options, live music, and a beer garden every Wednesday evening, and this year the market is set on the lawn for a picnic experience rather than a truck line along the parking edge. Returning April 1, 2026, the weekly market runs 5 to 9 p.m. with eight rotating food creators each week, live music, and a welcoming open-air setting where neighbors, families, and friends, including dogs, can gather.
If you have been going for years, the small tell is the chairs. Adirondack chairs are provided by OtG, and they are arranged for a picnic-style layout rather than perimeter seating. Bring a blanket if you want to claim your own footprint.
One date to keep off the calendar: the August 12 marketplace is canceled because of preparation for Foster City Summer Days.
What Is Different Off The Lagoon
Two changes across town are worth knowing about, because they will shape the fall in ways the weekend itself will not.
The first is at Edgewater Place. Osaka Market is opening a Foster City location in December. That fills the anchor slot at the shopping center at Edgewater Boulevard and gives the east side of the city a full grocery option again after a long stretch without one.
The second is a permit filing worth watching. A Preliminary Review application has been received for a new, approximately 6,000 square-foot stand-alone outdoor pavilion featuring restaurant and retail tenant spaces at 1065 E. Hillsdale Boulevard, at the southwest corner of Foster City Boulevard and E. Hillsdale Boulevard, with roughly 2,000 enclosed square feet across three restaurant and retail kiosks of varying sizes. That is the Century Plaza corner, directly across from the fire station and a short walk from the Community Center. If it moves forward, you will have a small dining node right where Summer Days parking already sits.
Neither of these is a splashy announcement. Both change the weeknight calculus of living here in ways that add up over a year.
The Sponsor List Is A Neighborhood Read In Itself
One small thing you can do with the 2026 Summer Concert Series page is scan the sponsor list. Sponsors include Edgewater Marine LLC, Kids Connection Private School, AAAAA Rent-A-Space, Crowne Plaza Foster City San Mateo, Happy Healthy Teeth, Jacklyn Kurth Orthodontics, Mariners Point Golf Center, Rotary Club of Foster City, St. Ambrose Episcopal Church and Sea Breeze School, and TownePlace Suites by Marriott San Mateo-Foster City. It is a compact map of the small businesses and civic institutions holding up the programming you actually use. Worth remembering the next time you need an orthodontist, a storage unit, or a place to put visiting in-laws.
Practical Notes For The Weekend
A short list of the things that catch people off guard even when they have done Summer Days before:
- After August 14, tickets can only be purchased onsite at the event, individual ride tickets are $1 equals one ride credit, and rides run 4 to 7 tickets each
- Dog friendly and all ages, so plan accordingly if you are bringing a pup for the first time
- Everything centers on Leo J. Ryan Park at 650 Shell Boulevard, so if a rideshare drop is easier than parking, use Hillsdale Boulevard as the pin
- Off the Grid runs the Wednesday before and the Wednesdays after, but not the week of the event
Why This Weekend Reads Differently If You Live Here
The reason Summer Days feels heavier this year is not the lineup. Mercy and the Heartbeats is a good Friday headliner. Tainted Love is a Tainted Love show. The Rubber Ducky Scavenger Hunt is a workaround for a construction constraint, not a headline. What is actually new is that the amphitheater end of the park works again as a place. The Wednesday market has moved onto the lawn. The Community Center is topped off. The east side of town has an anchor tenant signed for December. A pavilion permit is under review at the corner where you already park for events.
For a resident, those are not separate news items. They are the same story told in four locations. The center of Foster City is coming back into focus in the same summer, and August 14 to 16 is when most of us will see it in one place for the first time since 2023.
