↑ Rising The tide is rising. 5 h 44 min to high tide at 7:25 pm.
Tide coefficient 107 for the 3:53 am high tide and 112 for the 7:25 pm high tide. Big spring tides. The water rises and falls 0.9 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 15 (1.3 ft) and the lowest, on April 19 (-0.3 ft).
Mixed, mainly diurnal: on many days there is only one high and one low tide.
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 come from October 29 to 31 (coefficient 114, 0.9 ft range). The smallest, on October 24 (coefficient 20, 0.4 ft).

Where this tide comes from
Tomamae has no station of its own, so we use the tide at Rumoi (TICON-4), 25 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 waves you may find
- Most commonMost common3.1 ft

- Highest expectedHighest13 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 13 ft. Before heading out, expect waves of up to 13 ft.
Wind on the coast and offshore
Cross-shore wind. The coast faces west and the wind blows along the shore: drift and current run parallel to the beach.

Waves build over the next few days. The biggest waves arrive on Sunday 1: 11 ft with a period of 8 s, from the west-northwest (rough).
Water temperature

Surf in Tomamae today
Surf today
Good- 3.6–5.5 ft surf at the shore, a good size with some punch
- 5.1 ft swell at 6 s from the west, short: weak, messy waves
- Light offshore wind (8 mph): it holds up and grooms the waves
- First or last light of the day
- Rising tide (high tide at 7:25 pm)
- Light: First light 5:36 am · sunrise 6:06 am · sunset 4:28 pm · last light 4:58 pm
- Tide: high 3:53 am (1.0 ft), low 11:28 am (0.1 ft), high 7:25 pm (1.0 ft) and low 10:52 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 58.1 °F: a 4/3 fullsuit (booties if you run cold).
- Energy: 189 kJ · Medium power
Today’s surf at a glance
The best window, 4:00 pm to 4:58 pm, has a good size and light offshore wind, though with a short-period swell. 2:00 pm to 3:00 pm can also work, with a good size, though with 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 Tomamae today
Diving and snorkeling today
Likely visibility: poor- Slack water around low tide (11:28 am): little current from 11:13 am to 11:43 am
- 4.9 ft swell at 6 s from the west: strong surge on the bottom
- Light onshore wind (12 mph)
- 0.4 mph current toward the northeast, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 3:53 am (3:38–4:10 am), low tide 11:28 am (11:13–11:43 am), high tide 7:25 pm (7:10–7:50 pm) and low tide 10:52 pm (10:00 pm–12:20 am)
- Likely visibility: poor. Swell (up to 7.6 ft at 9 s) and rain (0.61 in) over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 58.1 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 4:58 pm. Waning gibbous (88%), rising at 6:14 pm: a bright night.
Your diving day at a glance
The best window, 11:00 am to 12:00 pm, 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 3:30 pm, with light wind and weak current, though with tidal current and some swell.
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- 12:33–2:33 am Major · the moon passes overhead · high activity
- 1:05–3:05 pm Major · the moon passes underfoot · high activity
- 9:25–10:25 am Minor · moonset · medium activity
- 5:44–6:44 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 0.9 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).
