Beach day in Ishikari
Is it a beach day?
- Sun and clouds
- Low tide at 11:33 am: more sand
- Feels like 42 °F: chilly for the beach
- Light offshore wind (11 mph): it blows floats and inflatables out to sea
- Dangerous for swimming: 6.9 ft waves every 7 s; high rip current risk
- Water at 57 °F (very cold)
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 · 6.9 ft
6.9 ft waves every 7 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 57 °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 11:33 am
Low tide at 11:33 am and 10:48 pm: that's when there's the most sand. High tide at 3:48 am and 7:31 pm.
We don't have data on jellyfish, sargassum or beach closures: ask the lifeguard or check with the local beach authority. How it works · The next 7 days

Tides in Ishikari
Today's high and low tides

- ▼ Low tide 10:48 pm 1.0 ft
↓ Falling The tide is falling. 3 h 37 min to low tide at 11:33 am.
Tide coefficient 108 for the 3:48 am high tide and 112 for the 7:31 pm high tide. Big spring tides. The water rises and falls 1.0 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 113, 1.0 ft range). The smallest, on October 24 (coefficient 20, 0.4 ft).

The sea at Ishikari
Sea stateSea state: moderate
The waves you may find
- Most commonMost common3.2 ft
- Significant6.3 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-offshore wind. The coast faces northwest and the wind comes off the land at an angle: calmer water near the shore, and bait and boats drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Sunday 1: 10 ft with a period of 7 s, from the west-northwest (rough).
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 54.7 °F by Wednesday 4.
Water colder than normal for late October (−1.0 °F).

Surf in Ishikari today
Surf today
Fair- 3.3–5.1 ft surf at the shore, a good size with some punch
- 5.1 ft swell at 6 s from the west-northwest, short: weak, messy waves
- Light offshore wind (7 mph): it holds up and grooms the waves
- Falling tide (low tide at 11:33 am)
- Light: First light 5:36 am · sunrise 6:05 am · sunset 4:31 pm · last light 5:00 pm
- Tide: high 3:48 am (1.1 ft), low 11:33 am (0.2 ft), high 7:31 pm (1.1 ft) and low 10:48 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 56.7 °F: a 5/4 fullsuit with booties (and a hood if it’s windy).
- Energy: 141 kJ · Medium power
Today’s surf at a glance
The best window, 8:00 am to 12:00 pm, has a good size and light offshore wind, though with a short-period swell. 1:00 pm to 3:00 pm can also work, with a good size and light offshore wind, 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 Ishikari today
Diving and snorkeling today
Likely visibility: poor- Slack water around low tide (11:33 am): little current from 11:18 am to 11:48 am
- 3.4 ft swell at 6 s from the north-northwest: some surge on the bottom
- Light offshore wind (9 mph)
- 0.2 mph current toward the west-southwest, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 3:48 am (3:30–4:03 am), low tide 11:33 am (11:18–11:48 am), high tide 7:31 pm (7:10–8:00 pm) and low tide 10:48 pm (10:00–11:40 pm)
- Likely visibility: poor. Swell (up to 5.8 ft at 8 s) and rain (0.37 in) over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 56.7 °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 5:00 pm. Waning gibbous (88%), rising at 6:21 pm: a bright night.
Your diving day at a glance
The best window, 11:10 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 1:00 pm to 2:20 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- 12:35–2:35 am Major · the moon passes overhead · high activity
- 1:07–3:07 pm Major · the moon passes underfoot · high activity
- 9:21–10:21 am Minor · moonset · medium activity
- 5:51–6:51 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.

- 66 ft deep2.2 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 950 ft): cast far from the beach and fish the high tide, when there is more water close in.
- Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
- Diving. 33 ft deep 0.6 mi from shore; 66 ft is far out (2.2 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).
