About Great Chebeague Island tides
Tide predictions for Great Chebeague Island come from NOAA station 8417881 (Maine), computed from long-term harmonic analysis of observed water levels. Heights are shown in feet relative to MLLW (Mean Lower Low Water) — the same datum used on US nautical charts — so they line up directly with charted depths.
Great Chebeague Island typically sees a mixed semidiurnal tide, with two highs and two lows of differing heights each day. Use the curve above to time a harbor entrance, a beach walk, fishing a moving tide, or clearing a shallow bar — and remember that wind and pressure can push the real water level above or below prediction. The daily tidal range in the 30-day table shows how much water moves each day: bigger ranges around the new and full moon mean stronger currents.
The current water temperature near Great Chebeague Island is about 59°F, from the nearest reporting buoy (Portland, ME buoy CASM1, 7 mi away). Water temperature shapes where fish hold and feed, and tells you what to wear in the water — check it alongside the tide before you head out.
Frequently asked
What time is high tide in Great Chebeague Island today?+
Today (Monday, October 5), high tide at Great Chebeague Island is at 7:00 AM (8.5 ft), 7:19 PM (9.7 ft). Heights are referenced to MLLW (Mean Lower Low Water).
What time is low tide in Great Chebeague Island today?+
Today, low tide at Great Chebeague Island is at 12:39 AM (0.4 ft), 12:56 PM (1.2 ft).
What tidal datum do these Great Chebeague Island tide heights use?+
All heights are given in feet relative to MLLW (Mean Lower Low Water), the standard NOAA chart datum for US tidal waters. A tide of 0.0 ft equals the chart datum; negative tides fall below it.
How accurate are these tide predictions?+
These are NOAA harmonic predictions — highly accurate for the astronomical tide. Real water levels can still differ with wind, barometric pressure, and storms, so always check current conditions before getting underway.
What is the water temperature at Great Chebeague Island?+
The latest sea-surface temperature near Great Chebeague Island is about 59°F, from the nearest reporting buoy (Portland, ME buoy CASM1, 7 mi away). Water temperature drives fish behavior and tells you what to wear in the water, so it's worth checking alongside the tide.
