  • Mostly sunny
  • Feels like 41 °F: chilly for the beach

Dangerous surf during beach hours. Stay out if the red flag is up, and never swim where there is no lifeguard.

Today, hour by hour

  • Swimming Dangerous · 6.2 ft

    6.2 ft waves every 9 s: dangerous for swimming. Stay out if the red flag is up. High rip current risk. If you're caught in a rip current, don't swim against it: swim parallel to shore and wave for help. Always follow the lifeguard's flags.

  • Water 51 °F

    Very cold: ease in and keep swims short.

  • Sun & sunscreen UV 2 · SPF 15

    Max UV 2 (low): SPF 15 sunscreen.

  • Wind 11 mph

    Offshore breeze (11 mph). Watch floats and inflatables: offshore wind carries them out to sea.

  • Tide & sand 11:46 pm

    Low tide at 11:46 pm: that's when there's the most sand. High tide at 3:30 pm. Coefficient 115 (spring tides): little sand left at high tide.

Today's high and low tides

  • ▼ Low tide 11:46 pm 0.1 ft

↑ Rising The tide is rising. 7 h 34 min to high tide at 3:30 pm.

Tide coefficient 115 for the 3:30 pm high tide. Big spring tides. The water rises and falls 4.4 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 December 25 (5.1 ft) and the lowest, on May 18 (-0.4 ft).

Mixed, mainly diurnal: on many days there is only one high and one low tide.

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 come from October 29 to 30 (coefficient 117, 4.4 ft range). The smallest, on October 23 (coefficient 20, 1.1 ft).

Where this tide comes from

B · Nearby station

Honmachi has no station of its own, so we use the tide at Abashiri (JMA), 20 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 best window, 5:23 am to 9:00 am, has 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.

Your diving day at a glance

The best window, 2:30 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 5:50 am to 8:50 am, with light wind and weak current, though with a big 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.

Solunar periods

Today's activity: medium
  • 12:21–2:21 am Major · the moon passes overhead · high activity

  • 9:10–10:10 am Minor · moonset · medium activity
  • 5:34–6:34 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

Gentle slope

The bottom slopes gently: 16 ft deep 470 ft from shore and 33 ft at 0.3 mi. Right off the beach it already drops to about 14 ft.

From the shoreline (0.55 mi from Honmachi) out to sea, heading north.

How far from shore

  • 16 ft deep470 ft
  • 33 ft deep0.3 mi
  • 66 ft deep1 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Deep water close in: about 14 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 0.3 mi from shore; 66 ft is far out (1 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.
