↓ Falling The tide is falling. 2 h 0 min to low tide at 10:46 am.
Tide coefficient 97 for the 2:47 am high tide and 92 for the 6:12 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 (1.7 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 101, 1.0 ft range). The smallest, on October 19 (coefficient 25, 0.6 ft).

Where this tide comes from
Itoigawa has no station of its own, so we use the tide at Naoetsu (JMA), 24 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 Itoigawa
Sea stateSea state: slight
The waves you may find
- Most commonMost common2.1 ft
- Significant4.1 ft
- Highest expectedHighest8.3 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 8.3 ft. Before heading out, expect waves of up to 8.3 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces north and the wind comes in from the sea at an angle: a bit more surf at the shore and drift along the coast, toward land.
Wave height, next 7 daysWaves, next 7 days
Waves ease over the next few days. The biggest waves arrive on Thursday 29: 5.2 ft with a period of 9 s, from the north-northwest (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 70.8 °F by Wednesday 4.
Water warmer than normal for late October (+3.0 °F).

Surf in Itoigawa today
Surf today
Good- 3.0–4.6 ft surf at the shore, a good size with some punch
- 4.1 ft swell at 7 s from the north, short: weak, messy waves
- Light offshore wind (4 mph): it holds up and grooms the waves
- Falling tide (low tide at 10:46 am)
- Light: First light 5:43 am · sunrise 6:09 am · sunset 4:55 pm · last light 5:22 pm
- Tide: high 2:47 am (1.4 ft), low 10:46 am (0.2 ft), high 6:12 pm (1.1 ft) and low 9:57 pm (1.0 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 71.6 °F: a rash guard or a neoprene top.
- Energy: 131 kJ · Medium power
Today’s surf at a glance
The best window, 6:00 am to 10:00 am, has a good size and light offshore wind, though with a short-period swell. 2:00 pm to 5:00 pm can also work, with a good size and glassy water, though with a short-period swell.
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 Itoigawa today
Diving and snorkeling today
Likely visibility: poor- Slack water around low tide (10:46 am): little current from 10:30 am to 11:01 am
- 3.4 ft swell at 6 s from the north: some surge on the bottom
- Light onshore wind (4 mph)
- 0.0 mph current toward the east, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 2:47 am (2:30–3:10 am), low tide 10:46 am (10:30–11:01 am), high tide 6:12 pm (5:40–7:00 pm) and low tide 9:57 pm (9:00–10:40 pm)
- Likely visibility: poor. Swell (up to 8.2 ft at 8 s) and rain (0.83 in) over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 71.6 °F: a 3 mm wetsuit.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 5:22 pm. Waning gibbous (88%), rising at 7:01 pm: a bright night.
Your diving day at a glance
The best window, 10:10 am to 11:20 am, combines slack water at low tide, light wind, weak current and the sun high, though with some swell. Also worth a look from 12:30 pm to 2:30 pm, with light wind, weak current and the sun high, though with tidal 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.

Moon phase and position
Today the moon is 226,480 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 12:49–2:49 am Major · the moon passes overhead · high activity
- 1:21–3:21 pm Major · the moon passes underfoot · high activity
- 9:10–10:10 am Minor · moonset · medium activity
- 6:31–7:31 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. 33 ft of water just 0.25 mi from shore: a good cast reaches deep water. Current and surf hit harder here.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. Shore diving works here: 33 ft at 0.25 mi and 66 ft at 0.3 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.
