Moving water at dawn and dusk —

The current runs fastest roughly halfway between a high and a low tide. Many anglers prefer those hours when they fall near sunrise or sunset. This is a rule of thumb, not a fishing forecast.

Questions about Boston tides

When are the highest tides of the year at Boston?

The highest predicted tide in the next 12 months is 11.8 ft on November 26, 2026 at 11:49 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 122 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -1.8 ft on January 23, 2027 at 5:49 PM. Minus tides expose the most shoreline, which is why tide-poolers look for them.

What time zone are these tide times in?

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.

Where does this tide data come from?

From NOAA CO-OPS, the U.S. government tide station network (tidesandcurrents.noaa.gov); the predictions are public domain. The curve between highs and lows is our interpolation. This page is not for navigation.
