Your day at a glance

The best window, 5:30 pm to 6:20 pm, combines the 6:31 pm low tide, sunset and some swell. Also good from 11:20 pm to 12:00 am, with the 12:25 am high tide and some swell.

Today's high and low tides

  • ▼ Low tide 5:34 am 0.2 ft
  • ▲ High tide 11:56 am 3.4 ft · coef. 87
  • ▼ Low tide 6:31 pm -0.1 ft

↑ Rising The tide is rising. 2 h 14 min to high tide at 12:25 am.

Tide coefficient 87 for the 11:56 am high tide. Average coefficient. The water rises and falls 3.5 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 14 (3.6 ft) and the lowest, on January 3 (-0.6 ft).

Mixed: two high and two low tides a day, but of quite different heights.

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 came from October 26 to 27 (coefficient 90, 3.6 ft range). The smallest, from October 17 to 19 (coefficient 44, 1.8 ft).

Where this tide comes from

A · Official station

Tides from the Threemile Harbor Entrance station (NOAA), 2.4 mi from Northwest Harbor. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the New London reference station with the official corrections.

How we calculate the tide

Sea and waves

The sea at Northwest Harbor

7-day waves

Sea stateSea state: slight

Slight Douglas 3 · light breeze, Beaufort 2
Waves 1.9 ft · 7.6 s from the southeast (124°)
Swell 1.8 ft · 6.5 s from the southeast
Current 0.3 mph toward the NE

The waves you may find

  • Most commonMost common1.0 ft
  • Significant1.9 ft
  • Highest expectedHighest3.9 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.9 ft. Before heading out, expect waves of up to 3.9 ft.

Wind on the coast and offshore

On the coast 6 mph SSW · gusts 9

The model doesn't separate offshore wind here: it's the same as on the coast.

Cross-offshore wind. The coast faces north and the wind comes off the land at an angle: calmer water near the shore, and bait and boats drift out to sea.

Waves stay much the same all week. The biggest waves arrive on Wednesday 28: 2.6 ft with a period of 9 s, from the east-southeast (slight).

Your diving day at a glance

The best window, 10:40 am to 1:00 pm, combines slack water at high tide, light wind, weak current and the sun high.

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.

Solunar periods

Today's activity: medium
  • 1:23–3:23 am Major · the moon passes overhead · high activity
  • 1:55–3:55 pm Major · the moon passes underfoot · high activity
  • 9:55–10:55 am Minor · moonset · medium activity
  • 6:51–7:51 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 0.4 mi from shore and 27 ft at 3.1 mi.

From the shoreline (2.5 mi from Northwest Harbor) out to sea, heading north.

How far from shore

  • 16 ft deep0.4 mi
  • 33 ft deepnot within 3.1 mi
  • 66 ft deepnot within 3.1 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Shallow, gradual bottom (16 ft at 0.4 mi): 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 3.1 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.
