Heights in feet above Mean Lower Low Water (MLLW). Dots are NOAA's predicted highs and lows; the line between them is our interpolation. Shaded: night.

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.
Iona Shores is a subordinate station: NOAA computes its tides from St. Petersburg with fixed time and height corrections.
On Tuesday, October 27, high tide at Iona Shores is at 3:06 AM (1.2 ft) and 6:13 PM (0.8 ft); low tide is at 11:28 AM (-0.1 ft) and 9:50 PM (0.7 ft) (EDT, heights above MLLW). The table above lists the next 7 days.
The highest predicted tide in the next 12 months is 1.3 ft on July 4, 2027 at 3:06 PM. The largest tides fall a day or two after a full or new moon, especially when the Moon is closest to Earth.
Yes — on 181 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -0.4 ft on January 21, 2027 at 9:29 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. Iona Shores is a subordinate station: NOAA derives its times and heights from the reference station St. Petersburg with fixed corrections. The curve between highs and lows is our interpolation.
