Your day at a glance

The best window, 4:00 pm to 5:00 pm, combines the 4:00 pm high tide and sunset. Also worth a try from 6:00 am to 6:50 am, with the 7:02 am high tide and sunrise, though with rising pressure. Also worth a try from 9:20 am to 10:20 am, with the 9:59 am low tide, moonset and some swell, though with rising pressure.

Today's high and low tides

  • ▼ Low tide 9:59 am 2.9 ft
  • ▼ Low tide 10:48 pm -0.1 ft

↑ Rising The tide is rising. 1 h 12 min to high tide at 4:00 pm.

Tide coefficient 94 for the 7:02 am high tide and 90 for the 4:00 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 (-0.5 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, 4.9 ft range). The smallest, on October 19 (coefficient 23, 2.3 ft).

Where this tide comes from

B · Nearby station

Yakumo has no station of its own, so we use the tide at Mori (JMA), 19 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 Yakumo

7-day waves

Sea stateSea state: moderate

Moderate Douglas 4 · moderate breeze, Beaufort 4
Waves 4.5 ft · 5.6 s from the southwest (233°)
Swell 2.8 ft · 5.1 s from the west-southwest
Current 0.2 mph toward the N

The waves you may find

  • Most commonMost common2.2 ft
  • Significant4.5 ft
  • Highest expectedHighest9.2 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 9.2 ft. Before heading out, expect waves of up to 9.2 ft.

Wind on the coast and offshore

On the coast 13 mph SSW · gusts 26
Offshore (12 mi E)Offshore 15 mph S · gusts 20

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

The best window, 8:00 am to 12:00 pm, has light offshore wind, 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, 9:30 am to 10:30 am, combines slack water at low tide, light wind, weak current and the sun high, though with some swell. Also worth a look from 6:30 am to 7:30 am, with slack water at high tide, light wind and weak current, though with some swell. Also worth a look from 12:00 pm to 1:20 pm, with weak current and the sun high, though with moderate 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: medium
  • 12:39–2:39 am Major · the moon passes overhead · high activity
  • 1:11–3:11 pm Major · the moon passes underfoot · high activity
  • 9:21–10:21 am Minor · moonset · medium activity
  • 6:00–7:00 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: you need to go 3.1 mi out for 33 ft of water.

From the shoreline (0.8 mi from Yakumo) out to sea, heading east.

How far from shore

  • 16 ft deep2.5 mi
  • 33 ft deep3.1 mi
  • 66 ft deepnot within 3.1 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Shallow, gradual bottom (16 ft at 2.5 mi): 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. Shallow near shore: you only reach 33 ft at 3.1 mi. For dives deeper than 33 ft, 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).
