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.
Steele Harbor Island is a subordinate station: NOAA computes its tides from Portland with fixed time and height corrections.
On Tuesday, October 27, high tide at Steele Harbor Island is at 11:40 AM (14.1 ft); low tide is at 5:36 AM (-0.1 ft) and 6:12 PM (-1.5 ft) (EDT, heights above MLLW). The table above lists the next 7 days.
The highest predicted tide in the next 12 months is 14.7 ft on December 25, 2026 at 10:56 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 141 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -2.3 ft on January 23, 2027 at 5:18 PM. 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. Steele Harbor Island is a subordinate station: NOAA derives its times and heights from the reference station Portland with fixed corrections. The curve between highs and lows is our interpolation.
