Today's high and low tides

  • ▼ Low tide 12:44 am 0.9 ft
  • ▲ High tide 8:23 am 12.3 ft · coef. 88
  • ▼ Low tide 1:19 pm 9.5 ft

↑ Rising The tide is rising. 3 h 7 min to high tide at 6:00 pm.

Tide coefficient 88 for the 8:23 am high tide and 87 for the 6:00 pm high tide. Average coefficient. The water rises and falls 11.4 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 January 4 (14.3 ft) and the lowest, on June 15 (-0.4 ft).

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

Heights above lower low water, large tide (LLWLT), the zero of Canadian 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. LLWLT

Tide coefficient and range in October

The biggest tides of the month came from October 26 to 28 (coefficient 90, 11.4 ft range). The smallest, from October 18 to 19 (coefficient 39, 8.0 ft).

Where this tide comes from

Tides from the Maple Bay station (TICON-4), 4.9 mi from Duncan. Times and heights are its predictions.

Sea and waves

The sea at Duncan

7-day waves

Sea stateSea state: calm (rippled)

Calm (rippled) Douglas 1 · light breeze, Beaufort 2
Waves 0.1 ft · 1.9 s from the northeast (51°)
Swell 0.1 ft · 1.5 s from the southeast

The waves you may find

  • Most commonMost common0.1 ft
  • Significant0.1 ft
  • Highest expectedHighest0.3 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 0.3 ft. Before heading out, expect waves of up to 0.3 ft.

Wind on the coast and offshore

Onshore wind. The coast faces southeast and the wind blows straight in from the sea: more surf and backwash at the shore, and bait and boats drift toward land.

Your diving day at a glance

The best window, 12:10 pm to 3:10 pm, combines slack water at low tide, little swell, light wind and the sun high. Also good from 8:00 am to 9:10 am, with slack water at high tide, little swell and light 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
  • 1:58–3:58 am Major · the moon passes overhead · high activity
  • 2:30–4:30 pm Major · the moon passes underfoot · high activity
  • 11:10 am–12:10 pm Minor · moonset · medium activity
  • 6:46–7:46 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.
