## How this forecast works

FloodRoute combines NOAA tide predictions for the Sausalito station with the elevation of every road segment in Greenbrae. When the predicted water level rises above a road's lowest point, it's marked — amber for possible, orange for likely, red for severe. The NOAA San Francisco gauge shows how far the water is actually running above or below the tide tables; that difference is carried into the forecast and fades over the following days. Recent rain raises the next 24 hours. After each high tide, streets stay marked a little longer, because water drains off the road more slowly than the tide falls.

**Estimates only.** Never drive through flood water — six inches can float a car. Follow local authorities.

## Frequently asked questions

### Which roads flood in Greenbrae?

The worst flood forecast in the next 30 days is Wed, Nov 25, 8:35 AM–2:25 PM PST (severe flooding likely). At its peak, 8 streets are forecast to flood: Irwin St, Fifer Ave, Lucky Dr, Redwood Hwy, Auburn St, Doherty Dr, Riviera Circle and McAllister Ave. The [live map](https://floodroute.com/ca/greenbrae) shows every street, hour by hour.

### When is the next flood in Greenbrae?

Thu, Oct 29, 12:00–4:00 PM PDT: severe flooding likely, peaking around 1:54 PM. FloodRoute forecasts 17 more flood windows in the next 30 days. See the [street-by-street forecast for that day](https://floodroute.com/ca/greenbrae/2026-10-29).

### How high does the tide have to be to flood roads in Greenbrae?

Roads start to flood when the water at NOAA's Sausalito station reaches about 6.6 ft (MLLW). Higher tides flood more streets, for longer. FloodRoute marks flooding as possible when the water is less than 0.5 ft above a road's low point, likely up to 1.5 ft, and severe at 1.5 ft or more.

### When is the next king tide in Greenbrae?

Tue, Nov 24 at 10:15 AM PST, with water expected around 7.8 ft at NOAA's Sausalito station. King tides are the year's highest predicted tides: FloodRoute uses the top 5% of high tides in NOAA's tide tables, 6.6 ft or more at NOAA's Sausalito station, about 18 days a year. Water often runs above the tide tables for weeks at a time (warm water, El Niño, storms). FloodRoute's flood forecasts include that, but it doesn't turn an ordinary high tide into a king tide.

### How can I get flood alerts for Greenbrae?

The free FloodRoute iPhone app gives you a heads-up before flood windows in your home town; FloodRoute Pro adds street-level alerts for your saved places and your commute. Without the app, subscribe to the [Greenbrae flood calendar](https://floodroute.com/cal/ca/greenbrae.ics) and flood days appear on your calendar automatically.

### How accurate is the Greenbrae flood forecast?

It's an estimate built from NOAA tide predictions for the Sausalito station, corrected with live readings from the NOAA San Francisco gauge, and the measured elevation of every road segment in Greenbrae. Wind, storm surge and blocked drains can change what actually floods. Never drive through flood water.
