Common Questions About Rio Vista, CA Tides

Show All
When is the lowest tide this week in Rio Vista, CA?

The lowest tide this week in Rio Vista, CA is -0.7 ft on Monday, Jun 15 at 11:53 am.

When is the highest tide this week in Rio Vista, CA?

The highest tide this week in Rio Vista, CA is 4.6 ft on Monday, Jun 15 at 3:06 am — worth noting for launching your boat and being alert for possible high tide flooding.

What time does the tide turn (slack tide) in Rio Vista, CA today?

Slack tide in Rio Vista, CA is approximately 2:28 am — midway between the next high and low tide, when tidal current is weakest. This is the preferred window for boat crossings, underwater visibility, and fishing in areas with strong currents.

Is this week a spring tide or neap tide in Rio Vista, CA?

Rio Vista, CA is currently in a neap phase. Tonight's moon is 46% illuminated. Spring tides (largest swings) occur near new and full moons; neap tides (smallest swings) occur near first and third quarter moons. Tidal ranges this week are near their weekly minimum.

What datum are Rio Vista, CA tide heights measured from?

Tide heights on this page are measured from Mean Lower Low Water (MLLW), the U.S. NOAA standard. A height of 0 ft represents the 19-year average of each day's lower low tide. Negative values indicate a "minus tide" — water levels below that long-term reference.

What factors can affect the tide predictions for Rio Vista, CA?

Tide predictions for Rio Vista, CA come from NOAA's harmonic analysis and are typically accurate within about ±10 minutes on timing and ±0.5 ft on height. Actual water levels can deviate further due to sustained winds, atmospheric pressure changes, river flow, and storm surge. During major weather events, be sure to check US Harbors weather pages for factors that could impact tidal predictions.

Which NOAA station provides tide data for Rio Vista, CA?

Tide data for Rio Vista, CA is sourced from NOAA Station #9415316. View the official NOAA station page at https://tidesandcurrents.noaa.gov/stationhome.html?id=9415316.

What time is high tide in Rio Vista, CA today?

High tides in Rio Vista, CA today: 9:28 am (2.7 ft), 11:00 pm (3.6 ft). The 11:00 pm high of 3.6 ft is notably higher than the other — known as diurnal inequality, common on coasts influenced by lunar declination.

What time is low tide in Rio Vista, CA today?

Low tides in Rio Vista, CA today: 4:43 am (1.4 ft), 4:30 pm (0.5 ft).

What is the tidal range in Rio Vista, CA today?

Today's tidal range in Rio Vista, CA is 3.2 ft — the difference between the day's highest and lowest water level. This month's average daily range is about 4.1 ft, so today's swing is below-average.

What is the moon phase in Rio Vista, CA tonight?

Tonight the moon over Rio Vista, CA is Third Quarter (46% illuminated). This places Rio Vista, CA in a neap tide cycle, so tidal ranges are near their weekly minimum this week.

What type of tides does Rio Vista, CA have — semi-diurnal, diurnal, or mixed?

Rio Vista, CA has semi-diurnal tides — two high tides and two low tides roughly every 24 hours and 50 minutes, with similar heights.

US Harbors Tidal Data

The data in our tide charts, tide tables, and tide graphs is provided by NOAA and others. These predictions are derived mathematically from numerous inputs, including data from historical tide stations and nearby locations where sensors are actively recording. As shown in the tide graph at the top of this page, “Predicted” tides (blue) are what forecasting models expect to happen. “Observed” tides (red) are those recorded by local sensors in real time, overlaid on the predictions for direct comparison. We display Observed water levels for a select group of harbors including Portland, Maine, where a physical sensor monitors water levels in real time.
