Common Questions About Shell Mound, Cedar Key, FL Tides

Show All
What time does the tide turn (slack tide) in Shell Mound, Cedar Key, FL today?

Slack tide in Shell Mound, Cedar Key, FL is approximately 8:54 pm — 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 Shell Mound, Cedar Key, FL?

Shell Mound, Cedar Key, FL is currently in a transitional phase. Tonight's moon is 65% 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 shifting between spring and neap.

What datum are Shell Mound, Cedar Key, FL 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 Shell Mound, Cedar Key, FL?

Tide predictions for Shell Mound, Cedar Key, FL 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 Shell Mound, Cedar Key, FL?

Tide data for Shell Mound, Cedar Key, FL is sourced from NOAA Station #8727535. View the official NOAA station page at https://tidesandcurrents.noaa.gov/stationhome.html?id=8727535.

What is the moon phase in Shell Mound, Cedar Key, FL tonight?

Tonight the moon over Shell Mound, Cedar Key, FL is First Quarter (65% illuminated). This places Shell Mound, Cedar Key, FL in a transitional tide cycle, so tidal ranges are shifting between spring and neap this week.

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.
