Today's high and low tides

- ▲ High tide 8:22 am 6.6 ft · coef. 93
- ▼ Low tide 1:52 pm 3.2 ft
- ▲ Next high tide 7:34 pm 6.7 ft · coef. 87
↑ Rising The tide is rising. 1 h 35 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
Koseda has no station of its own, so we use the tide at Tanegashima (TICON-4), 19 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 Koseda
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.2 ft
- Significant2.4 ft
- Highest expectedHighest4.8 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 4.8 ft. Before heading out, expect waves of up to 4.8 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Cross-offshore wind. The coast faces northeast 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 Wednesday 4: 7.9 ft with a period of 11 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 cools over the next few days: about 78.1 °F by Wednesday 4.
Water warmer than normal for late October (+2.0 °F).

Surf in Koseda today
Surf today
Fair- 1.5–2.3 ft surf at the shore, a fun size for most surfers
- 1.6 ft swell at 9 s from the east-southeast, a bit short
- Light offshore wind (12 mph): it holds up and grooms the waves
- Rising tide (high tide at 7:34 pm)
- Light: First light 6:04 am · sunrise 6:29 am · sunset 5:33 pm · last light 5:57 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 79.3 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 43 kJ · Low power
Today’s surf at a glance
The best window, 1:00 pm to 5:00 pm, has light offshore wind.
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 Koseda today
Diving and snorkeling today
Likely visibility: good- Slack water around low tide (1:52 pm): little current from 1:20 pm to 2:20 pm
- 1.6 ft swell at 9 s from the east-southeast: some surge on the bottom
- Light offshore wind (12 mph)
- 0.6 mph current toward the southeast (model)
- Sun high: more light underwater
- 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: good. Swell (up to 3.3 ft at 6 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 79.3 °F: a shorty or a rash guard.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 5:57 pm. Waning gibbous (88%), rising at 7:54 pm: a bright night.
Your diving day at a glance
The best window, 1:30 pm to 3:00 pm, combines slack water at low tide, light wind and the sun high, though with current. Also worth a look from 8:30 am to 9:30 am, with slack water at high tide 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.

The moon in Koseda
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
- 9:18–10:18 am Minor · moonset · medium activity
- 7:24–8:24 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.

Water depth
Drops off fastThe bottom drops off fast: the water is 33 ft deep just 550 ft from shore. It reaches 164 ft at 2.7 mi.
From the shoreline (0.45 mi from Koseda) out to sea, heading northeast.
How far from shore
- 16 ft deep380 ft
- 33 ft deep550 ft
- 66 ft deep1,050 ft
- 164 ft deep2.7 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 12 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; current and surf hit harder here.
- Swimming. The bottom drops quickly near the shore and you are soon out of your depth. Keep an eye on kids and weak swimmers.
- Diving. Shore diving works here: 33 ft at 550 ft and 66 ft at 1,050 ft 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.
