↓ Falling The tide is falling. 2 h 13 min to low tide at 10:37 am.
Tide coefficient 95 for the 6:04 am high tide and 90 for the 4:05 pm high tide. Spring tides. The water rises and falls 5.0 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 (5.0 ft) and the lowest, on May 18 (-0.6 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 104, 5.1 ft range). The smallest, on October 19 (coefficient 23, 2.3 ft).

Where this tide comes from
Ōtsuchi has no station of its own, so we use the tide at Kamaishi (Japan Coast Guard), 6.5 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.

The sea at Ōtsuchi
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.7 ft
- Significant1.4 ft
- Highest expectedHighest2.8 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.8 ft. Before heading out, expect waves of up to 2.8 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces east and the wind comes in from the sea at an angle: a bit more surf at the shore and drift along the coast, toward land.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Saturday 31: 5.1 ft with a period of 8 s, from the southeast (moderate).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water is steady these days, with no sudden changes.

Your diving day at a glance
The best window, 8:50 am to 11:50 am, combines slack water at low tide, little swell, light wind, weak current and the sun high. Also worth a look from 3:20 pm to 4:40 pm, with slack water at high tide, little swell and weak current, though with moderate wind. Also worth a look from 6:00 am to 7:10 am, 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.

The moon in Ōtsuchi
Moon phase and position
Today the moon is 226,480 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 12:32–2:32 am Major · the moon passes overhead · high activity
- 1:04–3:04 pm Major · the moon passes underfoot · high activity
- 9:02–10:02 am Minor · moonset · medium activity
- 6:05–7:05 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.
