  • A major period lines up with sunset

Bad weather during the best window: strong wind or big waves. If you go out, be very careful and stay off rocks and jetties.

Your day at a glance

The best window, 10:00 am to 11:00 am, combines the 10:59 am high tide and sunrise, though with strong wind. Also worth a try from 6:50 pm to 7:40 pm, with the 7:18 pm high tide, a major period and sunset, though with very strong wind and rough seas.

  • Tide & sand 2:25 am

    Low tide at 2:25 am and 2:44 pm: that's when there's the most sand. High tide at 10:59 am and 7:18 pm. Coefficient 115 (spring tides): little sand left at high tide.

Today's high and low tides

  • ▲ High tide 10:59 am 3.3 ft · coef. 115
  • ▼ Low tide 2:44 pm 3.1 ft
  • ▲ High tide 7:18 pm 3.4 ft · coef. 115

↓ Falling The tide is falling. 1 h 22 min to low tide at 2:25 am.

Tide coefficient 115 for the 10:59 am high tide and 115 for the 7:18 pm high tide. Big spring tides. The water rises and falls 4.5 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 December 23 (4.5 ft) and the lowest, on May 18 (-1.6 ft).

Mixed, mainly diurnal: on many days there is only one high and one low tide.

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 28 to 29 (coefficient 115, 4.5 ft range). The smallest, on October 8 (coefficient 20, 2.1 ft).

Where this tide comes from

Tides from the Otter Point station (NOAA), 2.9 mi from Umnak Pass. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the Unalaska reference station with the official corrections.

One wave in seven is higher than the significant height, and about 3 times a day one reaches 13 ft. Before heading out, expect waves of up to 13 ft.

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

Offshore wind. The coast faces north and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.

The best window, 4:00 pm to 8:00 pm, has a good size, though with a short-period swell and wind swell. 9:28 am to 1:00 pm can also work, though with a short-period swell and wind swell.

An estimate for this stretch of coast, not for a specific break: every beach or reef works its own way (its tide, bottom and angle). Check it when you get there.

Your diving day at a glance

The best window, 11:30 am to 2:30 pm, combines slack water at high tide, slack water at low tide, weak current and the sun high, though with some swell and strong 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.

Solunar periods

Today's activity: high
  • 5:07–7:07 am Major · the moon passes overhead · high activity

  • 2:59–3:59 pm Minor · moonset · medium activity
  • 9:21–10:21 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

Drops off fast

The bottom drops off fast: the water is 33 ft deep just 20 ft from shore. It reaches 164 ft at 90 ft.

From the shoreline out to sea, heading north.

How far from shore

  • 16 ft deep10 ft
  • 33 ft deep20 ft
  • 66 ft deep40 ft
  • 164 ft deep90 ft

For fishing, swimming and diving

  • Shore fishing. Deep water close in: about 316 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. Shore diving works here: 33 ft at 20 ft and 66 ft at 40 ft from shore.

Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).

Source: NOAA ETOPO 2022 (CC0), cells of about 0.3 mi; depth below mean sea level. For reference only: not for navigation or anchoring.
