Today's high and low tides

  • ▲ High tide 1:02 am 10.2 ft · coef. 85
  • ▼ Low tide 7:03 am 0.2 ft
  • ▲ High tide 1:14 pm 11.6 ft · coef. 85

↓ Falling The tide is falling. 1 h 47 min to low tide at 7:40 pm.

Tide coefficient 85 for the 1:02 am high tide and 85 for the 1:14 pm high tide. Average coefficient. The water rises and falls 12.7 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 (-1.6 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 85, 12.7 ft range). The smallest, from October 18 to 19 (coefficient 47, 6.2 ft).

Sea and waves

The sea at Suffolk Downs Station

7-day waves

Sea stateSea state: smooth

Smooth Douglas 2 · light breeze, Beaufort 2
Waves 0.9 ft · 5.8 s from the east-northeast (70°)

The waves you may find

  • Most commonMost common0.5 ft

  • Highest expectedHighest1.9 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 1.9 ft. Before heading out, expect waves of up to 1.9 ft.

Your diving day at a glance

The best window, 12:20 pm to 2:10 pm, combines slack water at high tide, little swell, light wind, weak current and the sun high. Also good from 6:40 am to 8:10 am, with slack water at low tide, little swell, light wind and weak 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.

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: you need to go 1.6 mi out for 33 ft of water.

From the shoreline (0.9 mi from Suffolk Downs Station) out to sea, heading east.

How far from shore

  • 16 ft deep1.1 mi
  • 33 ft deep1.6 mi
  • 66 ft deep3.1 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Shallow, gradual bottom (16 ft at 1.1 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 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.
