- ▲ Next high tide 11:01 am 14.2 ft · coef. 88
- ▼ Low tide 4:51 pm 4.3 ft
- ▲ High tide 10:38 pm 13.3 ft · coef. 84
↑ Rising The tide is rising. 2 h 13 min to high tide at 11:01 am.
Tide coefficient 88 for the 11:01 am high tide and 84 for the 10:38 pm high tide. Average coefficient. The water rises and falls 14.0 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 August 13 (15.3 ft) and the lowest, on December 25 (-1.2 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 99, 14.9 ft range). The smallest, from October 19 to 20 (coefficient 29, 4.5 ft).

Where this tide comes from
Matsubase has no station of its own, so we use the tide at Kumamoto (TICON-4), 9.2 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 Matsubase
Sea stateSea state: calm (rippled)
The waves you may find
- Most commonMost common0.1 ft
- Significant0.2 ft
- Highest expectedHighest0.4 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 0.4 ft. Before heading out, expect waves of up to 0.4 ft.
Wind on the coast and offshore
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.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Monday 2: 2.0 ft with a period of 4 s, from the southwest (slight).
Water temperature
Water temperature →The satellite measured 3.1 °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 71.6 °F by Wednesday 4.
Water warmer than normal for late October (+2.6 °F).

Your diving day at a glance
The best window, 10:10 am to 12:00 pm, combines slack water at high tide, little swell, light wind, weak current and the sun high. Also good from 4:10 pm to 5:30 pm, with slack water at low tide, little swell, light wind and weak 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 Matsubase
Moon phase and position
Today the moon is 226,480 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 1:19–3:19 am Major · the moon passes overhead · high activity
- 1:51–3:51 pm Major · the moon passes underfoot · high activity
- 9:25–10:25 am Minor · moonset · medium activity
- 7:16–8:16 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.
