Tides in Groton Long Point
Today's high and low tides
- ▼ Low tide 5:07 am 0.1 ft
- ▲ High tide 11:01 am 3.4 ft · coef. 91
- ▼ Next low tide 6:00 pm -0.1 ft
- ▲ High tide 11:28 pm 2.6 ft · coef. 88
↓ Falling The tide is falling. 4 min to low tide at 6:00 pm.
Tide coefficient 91 for the 11:01 am high tide and 88 for the 11:28 pm high tide. Spring tides. 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 (3.7 ft) and the lowest, on January 2 (-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 94, 3.7 ft range). The smallest, on October 18 (coefficient 38, 1.5 ft).

Where this tide comes from
Tides from the West Mystic station (NOAA), 2.6 mi from Groton Long Point. Times and heights are its predictions.

The sea at Groton Long Point
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.6 ft
- Significant1.1 ft
- Highest expectedHighest2.3 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.3 ft. Before heading out, expect waves of up to 2.3 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces west 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 Friday 30: 1.8 ft with a period of 4 s, from the south-southwest (slight).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water is steady these days, with no sudden changes.

Your diving day at a glance
The best window, 10:30 am to 12:00 pm, combines slack water at high tide, little swell, light wind and the sun high, though with current.
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.

Moon phase and position
Today the moon is 226,429 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 1:22–3:22 am Major · the moon passes overhead · high activity
- 1:54–3:54 pm Major · the moon passes underfoot · high activity
- 9:56–10:56 am Minor · moonset · medium activity
- 6:49–7:49 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.

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 950 ft): cast far from the beach and fish the high tide, when there is more water close in.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. Shallow near shore: you only reach 33 ft at 1.6 mi. For dives deeper than 33 ft, go by boat.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide.
