The National Oceanic and Atmospheric Administration (NOAA) Tide Predictions web page provides the high and low tide predictions for the United States, as well as sea level trends and forecasts of flooding. For details on accessing and understanding the tide predictions, see the NOAA User Guide (PDF, 13 MB) and the Frequently Asked Questions.
See the links below for the NOAA Tide Predictions pages that cover Massachusetts. For each available station, the plotted tide prediction is provided along with a link to a PDF copy of Annual Published Tide Tables. Please note: When using a mobile device, tide data are best viewed with phone held in landscape (horizontal) orientation.
- Massachusetts (from New Hampshire Border to Buzzards Bay, including Cape Cod and the Islands)
- Rhode Island (for Fall River, Mt. Hope Bay, and the Taunton River)
MyCoast: Massachusetts is an online portal and app that allows the public to collect and share photos of extreme high tides, coastal storm impacts, living shoreline projects, and more to help inform storm response and coastal management decisions. The app provides predicted and real-time tide data for nearby stations and allows you to set a reminder notification of the next high tide. Learn more at MyCoast: Massachusetts about this online portal and app.
And finally, the Massachusetts Marine Trades Association website also provides tides for Massachusetts and the US Harbors website has tides for all of Rhode Island (including Mount Hope Bay and Fall River), New Hampshire, and Maine.
