Tide coefficient 94 for the 6:57 am high tide and 90 for the 3:58 pm high tide. Spring tides. The water rises and falls 5.6 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 July 16 (5.7 ft) and the lowest, on December 24 (-0.4 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 11 to 12 (coefficient 103, 4.8 ft range). The smallest, on October 19 (coefficient 23, 2.3 ft).

Where this tide comes from

The sea at Muroran
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.6 ft
- Significant1.2 ft
- Highest expectedHighest2.5 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.5 ft. Before heading out, expect waves of up to 2.5 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Cross-onshore wind. The coast faces southeast 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 build over the next few days. The biggest waves arrive on Sunday 1: 6.2 ft with a period of 5 s, from the west (moderate).
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 53.8 °F by Wednesday 4.
Water colder than normal for late October (−4.6 °F).

Surf in Muroran today
Surf today
Flat- Barely any waves (0.8 ft sets): flat
- Fresh offshore wind (18 mph): it holds up and grooms the waves
- Falling tide (low tide at 9:58 am)
It’s flat today: almost no waves reach this coast.
- Light: First light 5:36 am · sunrise 6:05 am · sunset 4:34 pm · last light 5:03 pm
- Tide: high 6:57 am (4.4 ft), low 9:58 am (3.0 ft), high 3:58 pm (5.5 ft) and low 10:50 pm (-0.0 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 54.7 °F–57.2 °F: a 5/4 fullsuit with booties (and a hood if it’s windy).
- Energy: 11 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 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 Muroran today
Diving and snorkeling today
Likely visibility: fair- 0.7 ft swell at 11 s from the southeast: barely any surge
- Light onshore wind (11 mph)
- 0.5 mph current toward the east-northeast, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 6:57 am (5:30–7:12 am), low tide 9:58 am (9:43–10:13 am), high tide 3:58 pm (3:43–4:13 pm) and low tide 10:50 pm (10:35–11:05 pm)
- Likely visibility: fair. Rain (0.64 in) and wind over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 54.7–57.2 °F: a 7 mm semi-dry suit, with hood, gloves and booties.
- Snorkeling: good, calm sea and light wind.
- Night dive: dark from 5:03 pm. Waning gibbous (88%), rising at 6:26 pm: a bright night.
Your diving day at a glance
The best window, 11:50 am to 12:30 pm, combines little swell, light wind, weak current and the sun high. Also worth a look from 9:40 am to 10:20 am, with slack water at low tide, little swell, 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.

Moon phase and position
Today the moon is 226,480 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 12:36–2:36 am Major · the moon passes overhead · high activity
- 1:08–3:08 pm Major · the moon passes underfoot · high activity
- 9:18–10:18 am Minor · moonset · medium activity
- 5:56–6:56 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 1,300 ft 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 1,300 ft and 66 ft at 0.35 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).
