On a hot day in Sacramento, the easiest way to know Sherman Island is windy is to check the thermometer somewhere else entirely. Hot air rising over the Central Valley pulls cool, foggy marine air in from the San Francisco Bay, and it funnels straight through the Delta to this one low lying island.
Why Sherman Island?
Sherman Island sits at the heart of the Sacramento-San Joaquin River Delta, and local kiters describe it as one of the most consistently windy spots on the entire West Coast. The thermal effect is strong enough that when it is foggy at the Golden Gate and hot in Sacramento, the island almost always gets 20 knots or more, with wind often running most of the day and sometimes into the evening.
→ Typical wind speed runs 15 to 25 knots, with 20 plus on the strongest days, and the pattern often eases briefly around 11am before building back in by 2pm.
↳ The water is tidal river and slough, not open ocean. An ebb tide brings chop and swell, good for jumping, while a flood tide goes flat, better for practicing jibes, so check the tide chart alongside the wind forecast.
Getting There and Getting Around
- From San Francisco, it is just over an hour east via I-80 to Highway 12 to Highway 160. From the Sacramento side, take I-5 south to US-50, then Highway 12 west and Highway 160 south to Sherman Island Road.
- → The Antioch Bridge connects the island to Antioch on the south side, and the Three Mile Slough Bridge connects it north to Brannan Island State Recreation Area.
- ↳ Nearest airports are Oakland (OAK) and San Francisco (SFO). Day use parking at the official Sherman Island County Park runs $7 per vehicle, with camping for self-contained vehicles and RVs only at $35/night, up to 14 nights.
When to Kitesurf
The windy season runs roughly May through August, built around the classic Delta afternoon thermal pattern, with Labor Day weekend specifically called out as a big draw for the local scene. Hazards: this is not a beginner launch overall. The local kiteboarding community explicitly rates the area advanced, with real hazards, and the closest, most convenient launch known as the Access or the Pit is actually banned for kite launching under the site's state water lease terms after past rider misconduct, so use the official county park or Baja Road instead. Strong tidal current runs through the main channel, occasional ship and barge traffic passes through, and underwater debris and logs have been reported near some entry points. Launch areas get crowded and narrow as wind builds, with blackberry bushes and power lines near some access points, so stay at least 200 feet off the beach before attempting any tricks. True beginners can learn here, but normally only through a kite school using a jet ski assisted upwind tow, given the current.
