## How this forecast works

FloodRoute combines NOAA tide predictions for the Benicia station with the elevation of every road segment in Benicia. 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 Martinez-Amorco Pier 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.

Mon, Nov 23, 10:35–11:50 AM PST: minor flooding possible, peaking around 11:12 AM. FloodRoute forecasts 4 more flood windows in the next 30 days. See the [street-by-street forecast for that day](https://floodroute.com/ca/benicia/2026-11-23).

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

Roads start to flood when the water at NOAA's Benicia station reaches about 7.2 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 Benicia?

Tue, Nov 24 at 11:52 AM PST, with water expected around 7.6 ft at NOAA's Benicia station. King tides are the year's highest predicted tides: FloodRoute uses the top 5% of high tides in NOAA's tide tables, 6.3 ft or more at NOAA's Benicia 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 Benicia?

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 [Benicia flood calendar](https://floodroute.com/cal/ca/benicia.ics) and flood days appear on your calendar automatically.

### How accurate is the Benicia flood forecast?

It's an estimate built from NOAA tide predictions for the Benicia station, corrected with live readings from the NOAA Martinez-Amorco Pier gauge, and the measured elevation of every road segment in Benicia. Benicia is in Beta: community reports are still confirming which streets flood. Wind, storm surge and blocked drains can change what actually floods. Never drive through flood water.
