Where this tide comes from
Hamatonbetsu has no station of its own, so we use the tide at Esashi (Soya, JMA), 17 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 Hamatonbetsu
Sea stateSea state: moderate
The waves you may find
- Most commonMost common2.3 ft
- Significant4.5 ft
- Highest expectedHighest9.0 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 9.0 ft. Before heading out, expect waves of up to 9.0 ft.
Wind on the coast and offshore
Offshore wind. The coast faces northeast 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 stay much the same all week. The biggest waves arrive on Thursday 29: 5.8 ft with a period of 9 s, from the north-northeast (moderate).
Water temperature
Water temperature →The satellite measured 3.1 °F less 2 days ago than the model gives now: the water is probably colder 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 51.6 °F by Wednesday 4.
Water warmer than normal for late October (+3.9 °F).

Surf in Hamatonbetsu today
Surf today
Good- 3.6–5.5 ft surf at the shore, a good size with some punch
- 4.5 ft swell at 9 s from the northeast, a bit short
- Light offshore wind (11 mph): it holds up and grooms the waves
- Falling tide (low tide at 9:14 am)
- Light: First light 5:34 am · sunrise 6:04 am · sunset 4:23 pm · last light 4:54 pm
- Tide: high 5:57 am (2.4 ft), low 9:14 am (2.2 ft), high 3:07 pm (3.5 ft) and low 11:08 pm (-0.1 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 54.3 °F: a 5/4 fullsuit with booties (and a hood if it’s windy).
- Energy: 332 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.
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 Hamatonbetsu today
Diving and snorkeling today
Likely visibility: poor- Slack water around high tide (3:07 pm): little current from 2:50 pm to 3:22 pm
- 3.9 ft swell at 9 s from the northeast: strong surge on the bottom
- Light offshore wind (7 mph)
- 0.2 mph current toward the east-southeast, weak (model)
- Daylight
- Slack water today: high tide 5:57 am (5:10–7:20 am), low tide 9:14 am (8:10–9:40 am), high tide 3:07 pm (2:50–3:22 pm) and low tide 11:08 pm (10:53–11:23 pm)
- Likely visibility: poor. Swell (up to 4.6 ft at 9 s) and rain (0.51 in) over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 54.3 °F: a 7 mm semi-dry suit, with hood, gloves and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 4:54 pm. Waning gibbous (88%), rising at 6:07 pm: a bright night.
Your diving day at a glance
The best window, 1:50 pm to 3:50 pm, combines slack water at high tide, light wind and weak current, though with some swell. Also worth a look from 8:10 am to 9:30 am, with slack water at low tide, light wind and the sun high, though with some swell and 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- 12:30–2:30 am Major · the moon passes overhead · high activity
- 1:02–3:02 pm Major · the moon passes underfoot · high activity
- 9:26–10:26 am Minor · moonset · medium activity
- 5:37–6:37 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
Deepens quicklyThe bottom deepens quickly: 33 ft of water 0.25 mi from shore.
From the shoreline (0.4 mi from Hamatonbetsu) out to sea, heading northeast.
How far from shore
- 16 ft deep180 ft
- 33 ft deep0.25 mi
- 66 ft deep1.2 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 20 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; current and surf hit harder here.
- Swimming. The bottom drops quickly near the shore and you are soon out of your depth. Keep an eye on kids and weak swimmers.
- Diving. 33 ft deep 0.25 mi from shore; 66 ft is far out (1.2 mi): for deeper dives, go by boat.
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.
