- ▲ Next high tide 7:34 pm 6.7 ft · coef. 87
↑ Rising The tide is rising. 4 h 12 min to high tide at 7:34 pm.
Tide coefficient 93 for the 8:22 am high tide and 87 for the 7:34 pm high tide. Spring tides. The water rises and falls 6.6 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 September 12 (7.3 ft) and the lowest, on December 25 (-0.9 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, 6.7 ft range). The smallest, on October 19 (coefficient 24, 2.5 ft).

Where this tide comes from
Koshima has no station of its own, so we use the tide at Tanegashima (TICON-4), 30 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 Koshima
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.5 ft
- Significant3.0 ft
- Highest expectedHighest6.1 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 6.1 ft. Before heading out, expect waves of up to 6.1 ft.
Wind on the coast and offshore
Onshore wind. The coast faces south and the wind blows straight in from the sea: more surf and backwash at the shore, and bait and boats drift toward land.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Wednesday 4: 9.4 ft with a period of 11 s, from the southeast (rough).
Water temperature
Water temperature →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 78.7 °F by Wednesday 4.
Water warmer than normal for late October (+2.0 °F).

Surf in Koshima today
Surf today
Poor- 1.7–2.6 ft surf at the shore, a fun size for most surfers
- 2.1 ft swell at 9 s from the east-southeast, a bit short
- Light onshore wind (5 mph): a bit of chop
- Rising tide (high tide at 7:34 pm)
- Light: First light 6:05 am · sunrise 6:29 am · sunset 5:33 pm · last light 5:58 pm
- Tide: low 1:42 am (0.1 ft), high 8:22 am (6.6 ft), low 1:52 pm (3.2 ft) and high 7:34 pm (6.7 ft). Every break has its own tide: some work at low tide and others at high tide. The tide doesn’t change the score here.
- Water at 79.5 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 67 kJ · Low power
Today’s surf at a glance
The best window is 1:00 pm to 5:00 pm. 7:00 am to 8:00 am can also work, with glassy water, 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.
Diving in Koshima today
Diving and snorkeling today
Likely visibility: fair- Slack water around high tide (8:22 am): little current from 8:00 am to 8:40 am
- 2.0 ft swell at 9 s from the east-southeast: some surge on the bottom
- Light onshore wind (7 mph)
- 0.4 mph current toward the west-northwest, weak (model)
- Daylight
- Slack water today: low tide 1:42 am (1:20–2:00 am), high tide 8:22 am (8:00–8:40 am), low tide 1:52 pm (1:20–2:20 pm) and high tide 7:34 pm (7:10–8:00 pm)
- Likely visibility: fair. Swell (up to 6.8 ft at 7 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 79.5 °F: a shorty or a rash guard.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 5:58 pm. Waning gibbous (88%), rising at 7:55 pm: a bright night.
Your diving day at a glance
The best window, 8:00 am to 9:40 am, combines slack water at high tide, light wind and weak current. Also worth a look from 1:00 pm to 2:40 pm, with slack water at low tide, light wind and the sun high, 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.

The moon in Koshima
Moon phase and position
Today the moon is 226,480 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 1:20–3:20 am Major · the moon passes overhead · high activity
- 1:52–3:52 pm Major · the moon passes underfoot · high activity
- 9:18–10:18 am Minor · moonset · medium activity
- 7:25–8:25 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.

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 0.4 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. Shore diving works here: 33 ft at 0.45 mi and 66 ft at 0.55 mi from shore.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
Source: NOAA ETOPO 2022 (CC0), cells of about 0.3 mi; depth below mean sea level. For reference only: not for navigation or anchoring.
