Your day at a glance

The best window, 6:00 am to 6:50 am, combines the 6:57 am high tide, sunrise and some swell, though with rising pressure. Also worth a try from 3:50 pm to 5:00 pm, with the 3:58 pm high tide, sunset and a light onshore breeze, though with rising pressure. Also worth a try from 9:20 am to 10:20 am, with the 9:58 am low tide, moonset and a light onshore breeze, though with rising pressure.

↓ Falling The tide is falling. 2 h 10 min to low tide at 9:58 am.

Tide coefficient 94 for the 6:57 am high tide and 90 for the 3:58 pm high tide. Spring tides. The water rises and falls 5.6 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 July 16 (5.7 ft) and the lowest, on December 24 (-0.4 ft).

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

Heights above chart datum (CD), the zero of that port's 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. chart datum (CD)

Tide coefficient and range in October

The biggest tides of the month came from October 11 to 12 (coefficient 103, 4.8 ft range). The smallest, on October 19 (coefficient 23, 2.3 ft).

Where this tide comes from

B · Nearby station

Date has no station of its own, so we use the tide at Muroran (JMA), 9.2 mi away. On the open coast the difference is usually a few minutes and inches; inside estuaries, rivers and enclosed bays it can be much larger.

How we calculate the tide

Sea and waves

The sea at Date

7-day waves

Sea stateSea state: smooth

Smooth Douglas 2 · light breeze, Beaufort 2
Waves 1.4 ft · 4.1 s from the west (263°)
Swell 1.0 ft · 2.6 s from the west
Current 0.3 mph toward the SSE

The waves you may find

  • Most commonMost common0.7 ft
  • Significant1.4 ft
  • Highest expectedHighest3.1 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.1 ft. Before heading out, expect waves of up to 3.1 ft.

Wind on the coast and offshore

On the coast 4 mph W · gusts 17
Offshore (6.4 mi WNW)Offshore 6 mph W · gusts 16

Cross-shore wind. The coast faces south and the wind blows along the shore: drift and current run parallel to the beach.

Cross-shore Hourly wind →

Wave height, next 7 daysWaves, next 7 days

Waves build over the next few days. The biggest waves arrive on Sunday 1: 3.9 ft with a period of 5 s, from the west (slight).

Water temperature

Water temperature →
Water now54.1 °F
Today 53.8–54.3 °F air: 37 / 50 °F
Satellite (2 days ago) 58.1 °F measured 0.6 mi away

The satellite measured 4.0 °F more 2 days ago than the model gives now: the water is probably warmer than the forecast says.

Water temperature changes how fish behave: in very cold or very warm water they feed less. The water cools over the next few days: about 52.5 °F by Wednesday 4.

Water colder than normal for late October (−4.2 °F).

Your diving day at a glance

The best window, 9:30 am to 10:30 am, combines slack water at low tide, little swell, light wind, weak current and the sun high. Also good from 11:50 am to 1:30 pm, with little swell, light wind, weak current and the sun high. Also good from 6:10 am to 7:30 am, with slack water at high 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: medium
  • 12:37–2:37 am Major · the moon passes overhead · high activity
  • 1:09–3:09 pm Major · the moon passes underfoot · high activity
  • 9:19–10:19 am Minor · moonset · medium activity
  • 5:56–6:56 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.
