When is the highest tide this week in Vaca Key, Florida Bay, FL?

The highest tide this week in Vaca Key, Florida Bay, FL is 1.4 ft on Friday, Oct 16 at 4:50 am — worth noting for launching your boat and being alert for possible high tide flooding.

Is this week a spring tide or neap tide in Vaca Key, Florida Bay, FL?

Vaca Key, Florida Bay, FL is currently in a transitional phase. Tonight's moon is 23% 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 Vaca Key, Florida Bay, 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 Vaca Key, Florida Bay, FL?

Tide predictions for Vaca Key, Florida Bay, 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 Vaca Key, Florida Bay, FL?

Tide data for Vaca Key, Florida Bay, FL is sourced from NOAA Station #8723970. View the official NOAA station page at https://tidesandcurrents.noaa.gov/stationhome.html?id=8723970.

What time is high tide in Vaca Key, Florida Bay, FL today?

High tides in Vaca Key, Florida Bay, FL today: 4:05 am (1.4 ft).

What time is low tide in Vaca Key, Florida Bay, FL today?

Low tides in Vaca Key, Florida Bay, FL today: 10:24 am (0.2 ft).

What is the tidal range in Vaca Key, Florida Bay, FL today?

Today's tidal range in Vaca Key, Florida Bay, FL is 1.2 ft — the difference between the day's highest and lowest water level. This month's average daily range is about 0.9 ft, so today's swing is typical.

What is the moon phase in Vaca Key, Florida Bay, FL tonight?

Tonight the moon over Vaca Key, Florida Bay, FL is Waxing Crescent (23% illuminated). This places Vaca Key, Florida Bay, FL in a transitional tide cycle, so tidal ranges are shifting between spring and neap this week.

What type of tides does Vaca Key, Florida Bay, FL have — semi-diurnal, diurnal, or mixed?

Vaca Key, Florida Bay, FL has diurnal tides — one high tide and one low tide per day, roughly every 24 hours and 50 minutes.

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.

Quietly Sophisticated: The Hood 42 LM

By US Harbors At first glance, the Hood 42 LM might be confused for a boat that worked the Maine coast fifty years ago, but upon further inspection, the fifteen coats of Epifanes varnish over mahogany and custom-cast bronze hardware reveal that this boat was built for cruising.
