Today's high and low tides

  • ▲ High tide 3:45 am 9.9 ft · coef. 90
  • ▼ Low tide 8:51 am 3.3 ft
  • ▼ Low tide 9:46 pm -1.8 ft

↑ Rising The tide is rising. 12 min to high tide at 3:03 pm.

Tide coefficient 90 for the 3:45 am high tide and 88 for the 3:03 pm high tide. Spring tides. The water rises and falls 14.6 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 24 (13.9 ft) and the lowest, on June 16 (-3.4 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 28 (coefficient 92, 14.6 ft range). The smallest, from October 18 to 19 (coefficient 37, 7.4 ft).

Where this tide comes from

A · Official station

Tides from the Cosmopolis station (NOAA), 0.8 mi from Cosmopolis. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the Toke Point reference station with the official corrections.

Sea and waves

The sea at Cosmopolis

7-day waves

Sea stateSea state: slight

Slight Douglas 3 · light breeze, Beaufort 2
Waves 3.4 ft · 7.9 s from the west-northwest (282°)
Swell 3.4 ft · 6.6 s from the west-northwest
Current 0.1 mph toward the SSE

The waves you may find

  • Most commonMost common1.7 ft
  • Significant3.4 ft
  • Highest expectedHighest6.9 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 6.9 ft. Before heading out, expect waves of up to 6.9 ft.

Wind on the coast and offshore

On the coast 7 mph WSW · gusts 13
Offshore (11 mi WNW)Offshore 7 mph WSW · gusts 14

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

Your diving day at a glance

The best window, 2:10 pm to 3:50 pm, combines slack water at high tide, light wind, weak current and the sun high, though with some swell. Also worth a look from 8:20 am to 9:30 am, with slack water at low tide, light wind and weak current, though with some swell.

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
  • 1:58–3:58 am Major · the moon passes overhead · high activity
  • 2:30–4:30 pm Major · the moon passes underfoot · high activity
  • 11:00 am–12:00 pm Minor · moonset · medium activity
  • 6:57–7:57 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: 0 ft at 490 ft.

From the shoreline (1,100 ft from Cosmopolis) out to sea, heading northeast.

How far from shore

  • 16 ft deepnot within 490 ft
  • 33 ft deepnot within 490 ft
  • 66 ft deepnot within 490 ft
  • 164 ft deepnot within 490 ft

For fishing, swimming and diving

  • Shore fishing. Very shallow: the water doesn't reach 16 ft within 490 ft. Cast far from the beach, ideally around high tide.
  • 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 490 ft. 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) 490 ft out.
