In short

Tides in Boston are semidiurnal: two high and two low waters a day, each day about 50 minutes later than the day before. Today the range between low and high water is 2.8 m; at spring tides (new and full moon) it reaches 3.7 m, at neap tides about 1.7 m. Predictions use the harmonic constants of the nearest shore point, 0.3 km from the place; points run every 2 km along the coast.

Good to know in Boston

When to walk out at low tide

Next low tide is tomorrow at 08:48 (-1.0 m). The shore is widest for an hour either side of it; head back before the tide turns.

Where to park

Above the high-water mark: the next high tide is tomorrow at 03:00, +1.0 m, and the highest this month is +1.9 m. Shore-side stopovers are on the map with the tides layer.

Wind and pressure

Onshore wind and low pressure push the water above the prediction, offshore wind pulls it below. Hourly wind and rain are in the place card on the map.

Offline

In the CAMPLY app the phone calculates the tide itself, so the tide in Boston shows even with no signal.

FAQ

Questions about tides in Boston

When is high tide in Boston today?
High tide at 02:12 (+1.1 m) and at 14:19 (+1.4 m). Low tide at 08:03 (-1.1 m) and at 20:44 (-1.4 m). Local time (UTC−4).
What is the tidal range in Boston?
About 2.8 m today. At spring tides (new and full moon) up to 3.7 m, at neap tides about 1.7 m. Heights are relative to mean sea level.
How accurate are the predictions?
They use the harmonic constants of the nearest shore point — the same maths as published tide tables. Wind and air pressure can shift the level by tens of centimetres, so allow a margin at high water. Not for navigation.
Can I walk on the seabed at low tide?
The shore is widest for about two hours around low water. Head back before the tide turns: the water rises fast, and it is easy to get stuck on mudflats.
