Common Questions About Key Haven - Stock Island Channel, FL Tides

Show All
What time does the tide turn (slack tide) in Key Haven - Stock Island Channel, FL today?

Slack tide in Key Haven - Stock Island Channel, FL is approximately 8:57 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 Key Haven - Stock Island Channel, FL?

Key Haven - Stock Island Channel, FL 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 Key Haven - Stock Island Channel, 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 Key Haven - Stock Island Channel, FL?

Tide predictions for Key Haven - Stock Island Channel, 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 Key Haven - Stock Island Channel, FL?

Tide data for Key Haven - Stock Island Channel, FL is sourced from NOAA Station #8724517. View the official NOAA station page at https://tidesandcurrents.noaa.gov/stationhome.html?id=8724517.

What is the moon phase in Key Haven - Stock Island Channel, FL tonight?

Tonight the moon over Key Haven - Stock Island Channel, FL is First Quarter (46% illuminated). This places Key Haven - Stock Island Channel, FL in a neap tide cycle, so tidal ranges are near their weekly minimum 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.
