Summer Sliding Ends August 31: Last Call in Marin & SF

Last updated: August 2026

The goal this week isn't just booking a water slide — it's locking in one of the last guaranteed weekends of summer before the free concession add-on goes away. Once September starts, the offer resets to a different rental structure, and the free machine won't be back until next summer.

Why This Is the Last Real Push of Marin & SF's Summer Season

Labor Day weekend is the unofficial close of backyard water slide season across Marin and San Francisco, and the calendar between now and August 31 is the last stretch where Summer Sliding — free concession included — is still live. After that, fall event season takes over the calendar for schools, businesses, and community groups.

Families in San Rafael, Novato, Mill Valley, and across Marin County who want a slide weekend with the concession machine attached need to get on the schedule now. Remaining weekends fill first, and once they're gone, they're gone until next season.

The 4 Setups Marin & SF Families Order Most Before Summer Ends

1. Water Slide + Free Concession

The headline Summer Sliding setup — a full-size water slide paired with a free sno-cone, popcorn, or cotton candy machine. This is the combination families are booking first before the offer closes.

2. Combo Bounce & Slide Unit

For yards that need to do double duty — bounce space and a slide in one footprint. A common pick for mixed-age birthday parties where younger and older kids are both on the guest list.

3. Classic Bounce House

The straightforward option for smaller yards or hillside-access Marin properties. Still eligible for the free concession add-on through August 31.

4. Backyard Obstacle Course

For older kids and more active groups. Pairs well with the concession machine for longer parties that run through an afternoon.

Why Marin & SF Families Choose Astro Jump

Three reasons keep Marin and San Francisco families coming back to Astro Jump instead of booking a generic rental listing:

Astro Jump handles the Rec & Park permit paperwork. Public sites like Stafford Lake, McNears, and McInnis require permits before a unit can go up — Astro Jump manages that process instead of leaving it to the family.

Every unit is AIG-insured and state-inspected. That isn't a marketing line — it's paperwork you can ask to see before the truck ever leaves the warehouse.

Backup unit guarantee. If a unit has a mechanical issue on delivery day, a replacement is dispatched — the party doesn't get cancelled because of equipment.
