The best window, 4:40 pm to 5:20 pm, combines the 5:45 pm high tide and sunset, though with rising pressure. Also worth a try from 12:40 am to 1:20 am, with the 12:18 am low tide and a major period, though with rising pressure. Also worth a try from 11:30 am to 1:30 pm, with the 12:27 pm low tide and a major period, though with rising pressure.

  • ▼ Low tide 12:27 pm 3.4 ft

↑ Rising The tide is rising. 4 h 57 min to high tide at 5:45 pm.

Tide coefficient 93 for the 7:13 am high tide and 87 for the 5:45 pm high tide. Spring tides. The water rises and falls 5.7 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 September 12 (6.0 ft) and the lowest, on December 24 (-0.7 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 27 (coefficient 105, 5.8 ft range). The smallest, on October 19 (coefficient 20, 2.5 ft).

Sea and waves

The sea at Futtsu

7-day waves

Sea stateSea state: smooth

Smooth Douglas 2 · gentle breeze, Beaufort 3
Waves 1.0 ft · 5.3 s from the southeast (145°)

The waves you may find

  • Most commonMost common0.5 ft
  • Significant1.0 ft
  • Highest expectedHighest2.0 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.0 ft. Before heading out, expect waves of up to 2.0 ft.

Wind on the coast and offshore

On the coast 2 mph NNE · gusts 13
Offshore (5.7 mi SW)Offshore 10 mph N · gusts 18

Offshore wind. The coast faces south and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.

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.

Water about normal for late October.

Your diving day at a glance

The best window, 11:30 am to 1:00 pm, combines slack water at low tide, little swell, light wind, weak current and the sun high. Also worth a look from 6:10 am to 7:30 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.

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
  • 12:41–2:41 am Major · the moon passes overhead · high activity
  • 1:13–3:13 pm Major · the moon passes underfoot · high activity
  • 8:56–9:56 am Minor · moonset · medium activity
  • 6:29–7:29 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.
