Your day at a glance

The best window, 6:30 pm to 7:30 pm, combines the 6:30 pm high tide, moonrise, falling pressure and some swell. Also good from 9:10 pm to 11:10 pm, with the 10:06 pm low tide, falling pressure, a light onshore breeze and some swell. Also worth a try from 1:50 am to 2:50 am, with the 2:52 am high tide, a major period and a light onshore breeze, though with rising pressure.

  • ▼ Low tide 10:06 pm 1.1 ft

↓ Falling The tide is falling. 2 h 26 min to low tide at 11:07 am.

Tide coefficient 94 for the 2:52 am high tide and 89 for the 6:30 pm high tide. Spring tides. The water rises and falls 1.1 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 August 12 (1.6 ft) and the lowest, on April 19 (-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 27 to 28 (coefficient 99, 1.0 ft range). The smallest, from October 19 to 20 (coefficient 25, 0.6 ft).

Where this tide comes from

B · Nearby station

Sado has no station of its own, so we use the tide at Ryotsu (JMA), 5.7 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 Sado

7-day waves

Sea stateSea state: moderate

Moderate Douglas 4 · light breeze, Beaufort 2
Waves 5.1 ft · 7.5 s from the northwest (314°)
Swell 4.9 ft · 6.2 s from the northwest
Current 0.4 mph toward the ENE

The waves you may find

  • Most commonMost common2.6 ft
  • Significant5.1 ft
  • Highest expectedHighest10 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 10 ft. Before heading out, expect waves of up to 10 ft.

Wind on the coast and offshore

On the coast 2 mph ESE · gusts 8
Offshore (6.2 mi WSW)Offshore 4 mph E · gusts 12

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

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 68.5 °F by Wednesday 4.

Water warmer than normal for late October (+1.4 °F).

Your diving day at a glance

The best window, 10:20 am to 11:40 am, combines slack water at low tide, light wind, weak current and the sun high, though with some swell.

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
  • 12:47–2:47 am Major · the moon passes overhead · high activity
  • 1:19–3:19 pm Major · the moon passes underfoot · high activity
  • 9:12–10:12 am Minor · moonset · medium activity
  • 6:25–7:25 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.
