# Rio Vista, FL king tide and flood history since 2018

> Since 2018, NOAA's South Port Everglades tide gauge has recorded water high enough for FloodRoute's model to put at least one Rio Vista road at risk on 388 days, about 47 a year. The highest water was 4.92 ft on Sunday, September 27, 2026, 1.48 ft above the tide tables; at that level the model estimates 21 Rio Vista roads were at risk, including Mola Avenue, Coconut Isle Drive and Southeast 7th Street.

**Estimates, not records of actual flooding.** Each day is NOAA's verified high water at the tide gauge, run through FloodRoute's flood model on today's roads and elevations, in dry weather. Drains, levees, tide gates, rain, road changes and elevation error all mean real conditions differed. Not for property, real-estate, insurance, lending, engineering or legal decisions.

## Method

For every day since 1996 we take NOAA's verified highest observed water at the tide gauge, adjust it to the town's prediction station exactly as the live forecast does (the gauge's departure from the tide tables, minus the departure already built into our calibration), and run FloodRoute's flood model on today's road network and street elevations. A day counts when at least one road in the town is at or below that water level by the model's rules. Rain is not included, so wet days were likely worse.

## Frequently asked questions

### How often do roads flood at high tide in Rio Vista?

By FloodRoute's estimate, at least one Rio Vista road was at risk on 388 days between 2018 and Sep 30, 2026, about 47 a year. Most of those days are shallow water on a few low streets; the [biggest days](https://floodroute.com/fl/rio-vista/history) put dozens of roads at risk.

### What was the highest tide in Rio Vista since 2018?

Sunday, September 27, 2026: NOAA's South Port Everglades tide gauge recorded 4.92 ft (MLLW), 1.48 ft above the tide tables. At that level FloodRoute's model estimates 21 Rio Vista roads were at risk, including Mola Avenue, Coconut Isle Drive and Southeast 7th Street.

### When did a high tide last put Rio Vista roads at risk?

The most recent day in the verified record is Wednesday, September 30, 2026: 4.24 ft at the South Port Everglades gauge, 5 roads at risk. NOAA verifies data with a lag of a month or two; the [live forecast](https://floodroute.com/fl/rio-vista) covers today and the weeks ahead.

### Is this a record of actual flooding in Rio Vista?

No. Estimates, not records of actual flooding. Each day is NOAA's verified high water at the tide gauge, run through FloodRoute's flood model on today's roads and elevations, in dry weather. Drains, levees, tide gates, rain, road changes and elevation error all mean real conditions differed. Not for property, real-estate, insurance, lending, engineering or legal decisions. Neighbor flood reports in the FloodRoute app are the ground truth we use to check and improve the model.

### Can I use this data?

Yes. Download it as [CSV](https://floodroute.com/data/history/fl/rio-vista.csv) or [JSON](https://floodroute.com/data/history/fl/rio-vista.json) under the Open Database License (ODbL) 1.0, with attribution to FloodRoute (floodroute.com), © OpenStreetMap contributors, NOAA CO-OPS. Please describe it as estimates, never as observed flooding. More on the [open data page](https://floodroute.com/data).

**Forecasts are estimates, not guarantees.** Never drive or walk through flood water: according to the National Weather Service, a foot of moving water can carry away most cars. Turn around, don’t drown. Always follow local authorities and official warnings.
