↓ Falling The tide is falling. 2 h 23 min to low tide at 11:04 am.
Tide coefficient 96 for the 3:03 am high tide and 91 for the 6:41 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 11 (1.6 ft) and the lowest, on April 19 (-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 27 to 28 (coefficient 99, 1.0 ft range). The smallest, on October 19 (coefficient 24, 0.6 ft).

The sea at Seirō
Sea stateSea state: moderate
The waves you may find
- Most commonMost common2.7 ft
- Significant5.3 ft
- Highest expectedHighest11 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 11 ft. Before heading out, expect waves of up to 11 ft.
Wind on the coast and offshore
Offshore wind. The coast faces northwest and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves ease over the next few days. The biggest waves arrive on Thursday 29: 7.5 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 68.7 °F by Wednesday 4.
Water warmer than normal for late October (+2.5 °F).

Surf in Seirō today
Surf today
Good- 3.5–5.4 ft surf at the shore, a good size with some punch
- 4.8 ft swell at 7 s from the north-northwest, short: weak, messy waves
- Light offshore wind (7 mph): it holds up and grooms the waves
- Falling tide (low tide at 11:04 am)
- Light: First light 5:38 am · sunrise 6:05 am · sunset 4:48 pm · last light 5:15 pm
- Tide: high 3:03 am (1.3 ft), low 11:04 am (0.2 ft), high 6:41 pm (1.1 ft) and low 9:35 pm (1.1 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 70.2 °F: a springsuit or a 2 mm fullsuit.
- Energy: 199 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. 4:00 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 Seirō today
Diving and snorkeling today
Likely visibility: poor- Slack water around low tide (11:04 am): little current from 10:49 am to 11:20 am
- 3.6 ft swell at 7 s from the north: some surge on the bottom
- Almost no wind
- 0.1 mph current toward the east, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 3:03 am (2:48–3:20 am), low tide 11:04 am (10:49–11:20 am), high tide 6:41 pm (6:10–7:40 pm) and low tide 9:35 pm (8:20–10:40 pm)
- Likely visibility: poor. Swell (up to 9.4 ft at 8 s) and rain (0.20 in) over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 70.2 °F: a 5 mm wetsuit.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 5:15 pm. Waning gibbous (88%), rising at 6:52 pm: a bright night.
Your diving day at a glance
The best window, 10:20 am to 11:40 am, combines slack water at low tide, light wind, weak current and the sun high, though with some swell. Also worth a look from 1:30 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- 12:43–2:43 am Major · the moon passes overhead · high activity
- 1:16–3:16 pm Major · the moon passes underfoot · high activity
- 9:08–10:08 am Minor · moonset · medium activity
- 6:22–7:22 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 deep0.65 mi
- 164 ft deepnot within 3.1 mi
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 0.65 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).
