Your day at a glance

The best window, 4:00 pm to 5:10 pm, combines the 4:26 pm high tide, sunset, a light onshore breeze and some swell, though with rising pressure. Also worth a try from 5:40 am to 6:30 am, with the 5:34 am high tide and sunrise, though with rising pressure. Also worth a try from 9:30 am to 10:20 am, with the 10:30 am low tide and moonset, though with rising pressure.

  • ▼ Low tide 11:43 pm 0.2 ft

↑ Rising The tide is rising. 4 h 2 min to high tide at 4:26 pm.

Tide coefficient 96 for the 5:34 am high tide and 92 for the 4:26 pm high tide. Spring tides. The water rises and falls 3.3 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 15 (3.5 ft) and the lowest, on April 19 (-0.3 ft).

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

Heights above NLLW. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. NLLW

Tide coefficient and range in October

The biggest tides of the month came from October 26 to 28 (coefficient 103, 3.4 ft range). The smallest, on October 19 (coefficient 21, 1.3 ft).

Where this tide comes from

B · Nearby station

Kikonai has no station of its own, so we use the tide at Hakodate (TICON-4), 17 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.

Sea and waves

The sea at Kikonai

7-day waves

Sea stateSea state: smooth

Smooth Douglas 2 · moderate breeze, Beaufort 4
Waves 1.4 ft · 5.2 s from the south-southwest (199°)
Swell 0.7 ft · 9.2 s from the east-southeast
Current 0.5 mph toward the WSW

The waves you may find

  • Most commonMost common0.7 ft
  • Significant1.4 ft
  • Highest expectedHighest2.9 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.9 ft. Before heading out, expect waves of up to 2.9 ft.

Wind on the coast and offshore

On the coast 11 mph SSW · gusts 27
Offshore (13 mi SSE)Offshore 17 mph SW · gusts 22

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

Waves stay much the same all week. The biggest waves arrive on Friday 30: 3.0 ft with a period of 5 s, from the south-southwest (slight).

Water temperature

Water now62.4 °F
Today 62.1–62.6 °F air: 40 / 55 °F
Satellite (2 days ago) 65.1 °F measured 1.0 mi away

The satellite measured 2.7 °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 59.5 °F by Wednesday 4.

Water colder than normal for late October (−2.0 °F).

The best window, 6:00 am to 10:00 am, has glassy water, though with barely any waves.

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.

Follow the flags and the lifeguards, and don’t paddle out if the surf is above your level: this score is a guide, not a substitute for what you see when you get there.

Your diving day at a glance

The best window, 9:10 am to 11:40 am, combines slack water at low tide, little swell, light wind, weak current and the sun high. Also good from 5:40 am to 8:00 am, with slack water at high tide, little swell, light wind and weak current. Also worth a look from 3:50 pm to 4:40 pm, with slack water at high tide, little swell and light wind, though with 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
  • 12:38–2:38 am Major · the moon passes overhead · high activity
  • 1:11–3:11 pm Major · the moon passes underfoot · high activity
  • 9:18–10:18 am Minor · moonset · medium activity
  • 6:02–7:02 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

Gentle slope

The bottom slopes gently: 16 ft deep 850 ft from shore and 33 ft at 0.35 mi.

From the shoreline (0.65 mi from Kikonai) out to sea, heading southeast.

How far from shore

  • 16 ft deep850 ft
  • 33 ft deep0.35 mi
  • 66 ft deep1.6 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Shallow, gradual bottom (16 ft at 850 ft): 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. 33 ft deep 0.35 mi from shore; 66 ft is far out (1.6 mi): for deeper dives, go by boat.

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