About Maine Tides

Some of the most dramatic tides on the East Coast

Maine's tidal range increases dramatically from south to north. Portland sees swings of roughly 9–11 feet, while Eastport — near the Canadian border and adjacent to the Bay of Fundy — experiences some of the largest tides in the contiguous United States, often reaching 18–20 feet.

TideSwell maps all of it in one place. Each station shows a live tide curve so you can see not just current water level but whether it's rising or falling, how fast, and what's coming next — all overlaid on nautical charts showing water depth.

FAQ

Maine tide questions

What are the tides like in Maine?
Maine has some of the most dramatic tidal ranges on the US East Coast. Tidal swings increase from south to north — Portland sees roughly 9–11 feet, while Eastport near the Canadian border can see swings of 18–20 feet due to its proximity to the Bay of Fundy.
How many stations does TideSwell cover in Maine?
TideSwell covers 34 NOAA tide stations across Maine and New Hampshire, from Kittery and Portsmouth in the south to Eastport and Lubec near the Canadian border — including Portland, Rockland, Bar Harbor, Boothbay Harbor, Machias, and Penobscot Bay stations.
Is TideSwell data accurate for Maine tides?
Yes. All data comes directly from NOAA in real time — the same source used by the Coast Guard and NOAA's own tide prediction pages. TideSwell displays that data visually so it's faster to read and easier to interpret than raw tables.
Can I see tide charts for Acadia / Bar Harbor specifically?
Yes. Bar Harbor is one of the stations included in the Maine region. You can click any station on the map to see a live tide curve showing current level, direction, and upcoming highs and lows.
