Your day at a glance

The best window, 6:40 am to 7:50 am, combines the 7:05 am low tide, sunrise and some swell, though with rising pressure. Also worth a try from 1:20 am to 2:00 am, with the 1:02 am high tide, a major period and some swell, though with rising pressure. Also good from 6:40 pm to 7:40 pm, with the 7:43 pm low tide and moonrise.

Species with the most records nearby: winter flounder, Atlantic cod, pollock and striped bass. October is one of the months when these are seen most: winter flounder and longfin inshore squid. What you can catch

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

↓ Falling The tide is falling. 1 h 46 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).

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.

Today the moon is 226,429 mi away and looks 32′ 47″ across.

Solunar periods

Today's activity: high
  • 1:18–3:18 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, gradual

Shallow, gradual bottom: 16 ft at 1,150 ft from shore and 0.3 ft at 1.7 mi.

From the shoreline (0.6 mi from East Somerville) out to sea, heading east.

How far from shore

  • 16 ft deep1,150 ft
  • 33 ft deepnot within 1.7 mi
  • 66 ft deepnot within 1.7 mi
  • 164 ft deepnot within 1.7 mi

For fishing, swimming and diving

  • Shore fishing. Shallow, gradual bottom (16 ft at 1,150 ft): cast far from the beach and fish the high tide, when there is more water close in.
  • Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
  • Diving. Shallow: the water doesn't reach 33 ft within 1.7 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) 1.7 mi out. The profile is turned slightly from the coast so it does not run into an island or a headland.
