↓ Falling The tide is falling. 2 h 4 min to low tide at 12:04 pm.
Tide coefficient 94 for the 7:06 am high tide and 89 for the 5:27 pm high tide. Spring tides. The water rises and falls 5.2 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 14 (5.3 ft) and the lowest, on December 24 (-0.6 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 106, 5.1 ft range). The smallest, on October 19 (coefficient 21, 2.2 ft).

The sea at Ōshima
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.7 ft
- Significant3.5 ft
- Highest expectedHighest7.2 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 7.2 ft. Before heading out, expect waves of up to 7.2 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 west 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: 7.2 ft with a period of 8 s, from the east-northeast (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 74.6 °F by Wednesday 4.
Water warmer than normal for late October (+3.7 °F).

Surf in Ōshima today
Surf today
Poor- 0.7–1.1 ft surf at the shore, small: good for learning or a longboard
- 1.6 ft swell at 6 s from the east-southeast, short: weak, messy waves; this coast faces away from it
- 2.4 ft wind swell at 4 s: messy waves
- Fresh offshore wind (19 mph): it holds up and grooms the waves
- Rising tide (low tide at 12:04 pm)
- Light: First light 5:34 am · sunrise 6:00 am · sunset 4:52 pm · last light 5:18 pm
- Tide: low 12:05 am (-0.0 ft), high 7:06 am (4.7 ft), low 12:04 pm (3.2 ft) and high 5:27 pm (5.2 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 75.9 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 30 kJ · Low power
Today’s surf at a glance
The best window, 6:00 am to 10:00 am, has light offshore wind, though with small waves, a short-period swell and wind 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 Ōshima today
Diving and snorkeling today
Likely visibility: good- 2.1 ft swell at 4 s from the east-southeast: some surge on the bottom
- Moderate offshore wind (18 mph): it pushes surface swimmers away from shore
- 0.5 mph current toward the north-northwest, weak (model)
- Sun high: more light underwater
- Slack water today: low tide 12:05 am (11:50 pm–12:20 am), high tide 7:06 am (6:40–7:30 am), low tide 12:04 pm (11:30 am–12:30 pm) and high tide 5:27 pm (5:00–5:50 pm)
- Likely visibility: good. Swell (up to 4.1 ft at 6 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 75.9 °F: a 3 mm wetsuit.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 5:18 pm. Waning gibbous (88%), rising at 7:03 pm: a bright night.
Your diving day at a glance
The best window, 12:30 pm to 1:20 pm, combines weak current and the sun high, though with moderate wind. Also worth a look from 6:40 am to 7:40 am, with slack water at high tide and weak current, though with fresh wind.
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 Ōshima
Moon phase and position
Today the moon is 226,480 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 12:43–2:43 am Major · the moon passes overhead · high activity
- 1:15–3:15 pm Major · the moon passes underfoot · high activity
- 8:56–9:56 am Minor · moonset · medium activity
- 6:33–7:33 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

- 66 ft deep0.55 mi
- 164 ft deep0.6 mi
For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 0.35 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).
