Orange: measured by NOAA's sensor, last 24 hours (6-minute data, preliminary). Dashed: predicted tide, through the next 24 hours. The prediction contains only the astronomical tide; wind, air pressure and river flow move the real water level away from it.
Knockemdown Key, north end is a subordinate station: NOAA computes its tides from Key West with fixed time and height corrections.
On Tuesday, October 27, high tide at Knockemdown Key, north end is at 1:53 AM (3.4 ft) and 3:24 PM (2.3 ft); low tide is at 9:54 AM (-0.0 ft) and 9:21 PM (1.0 ft) (EDT, heights above MLLW). The table above lists the next 7 days.
The highest predicted tide in the next 12 months is 3.4 ft on October 28, 2026 at 2:34 AM. The largest tides fall a day or two after a full or new moon, especially when the Moon is closest to Earth.
Yes — on 176 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -0.8 ft on January 21, 2027 at 7:41 AM. Minus tides expose the most shoreline, which is why tide-poolers look for them.
Station local time (EDT at the time this page was built), with daylight saving time applied where the area observes it — the same convention as NOAA's own tide tables.
From NOAA CO-OPS, the U.S. government tide station network (tidesandcurrents.noaa.gov); the predictions are public domain. Knockemdown Key, north end is a subordinate station: NOAA derives its times and heights from the reference station Key West with fixed corrections. The curve between highs and lows is our interpolation. This page is not for navigation.
