Tides in Cambridge
Today's high and low tides
- ▲ High tide 1:02 am 10.2 ft · coef. 85
- ▼ Low tide 7:05 am 0.1 ft
- ▲ High tide 1:13 pm 11.7 ft · coef. 86
- ▼ Next low tide 7:43 pm -1.2 ft
↓ Falling The tide is falling. 2 h 51 min to low tide at 7:43 pm.
Tide coefficient 85 for the 1:02 am high tide and 86 for the 1:13 pm high tide. Average coefficient. The water rises and falls 12.9 ft between the highest high and the lowest low: a large range for this place. 70 is an average tide here; 90 and above means spring tides; below 45, neap tides. What is the tide coefficient?
2026 extremes: the highest tide of the year is on June 16 (12.1 ft) and the lowest, on December 25 (-1.7 ft).
Semidiurnal: two high and two low tides a day, of similar height.
Heights above mean lower low water (MLLW), the zero of US nautical charts. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. MLLW
Tide coefficient and range in October
The biggest tides of the month come from October 27 to 29 (coefficient 86, 12.9 ft range). The smallest, from October 18 to 20 (coefficient 47, 6.3 ft).

Where this tide comes from
Cambridge has no station of its own, so we use the tide at Amelia Earhart Dam (NOAA), 2.0 mi away. On the open coast the difference is usually a few minutes and inches; inside estuaries, rivers and enclosed bays it can be much larger.
Station data attribution: Slackwater database (https://github.com/openwatersio/slackwater-database)
The sea at Cambridge
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.8 ft
- Significant1.6 ft
- Highest expectedHighest3.3 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.3 ft. Before heading out, expect waves of up to 3.3 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces east and the wind comes in from the sea at an angle: a bit more surf at the shore and drift along the coast, toward land.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Wednesday 28: 2.4 ft with a period of 6 s, from the east (slight).

Your diving day at a glance
The best window, 12:20 pm to 2:10 pm, combines slack water at high tide, small waves, light wind and the sun high. Also good from 6:40 am to 8:10 am, with slack water at low tide, small waves and light wind.
Slack water comes from the tide: in inlets, channels and between islands the water can keep running for an hour or two after. Ask the local dive shop.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

The moon in Cambridge
Moon phase and position
Today the moon is 226,429 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 1:19–3:19 am Major · the moon passes overhead · high activity
- 1:50–3:50 pm Major · the moon passes underfoot · high activity
- 9:56–10:56 am Minor · moonset · medium activity
- 6:40–7:40 pm Minor · moonrise · medium activity
According to solunar theory, fish feed more when the moon passes overhead or underfoot (major periods, about 2 h) and when it rises or sets (minor periods, 1 h). It works best around new and full moon.

Water depth
Shallow, gradualShallow, gradual bottom: 16 ft at 140 ft from shore and 0.7 ft at 0.9 mi. Right off the beach it already drops to about 19 ft.
From the shoreline (2.3 mi from Cambridge) out to sea, heading northeast.
How far from shore
- 16 ft deep140 ft
- 33 ft deepnot within 0.9 mi
- 66 ft deepnot within 0.9 mi
- 164 ft deepnot within 0.9 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 19 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; current and surf hit harder here.
- Swimming. The bottom drops quickly near the shore and you are soon out of your depth. Keep an eye on kids and weak swimmers.
- Diving. Shallow: the water doesn't reach 33 ft within 0.9 mi. For deeper dives, take a boat farther out.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide. There is land ahead (an island, a headland or the far shore) 0.9 mi out. The profile is turned slightly from the coast so it does not run into an island or a headland. Right by the shore the bottom may drop even faster than shown. Where the bottom comes up to the surface there are shoals, rocks or an islet next to the profile.
