Beach day in Nagatoyomachi
Is it a beach day?
- Cloudy (86% cloud cover)
- Feels like 45 °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 · 7.2 ft
7.2 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.

Very cold: ease in and keep swims short.
- Sun & sunscreen UV 2 · SPF 15
Max UV 2 (low): SPF 15 sunscreen.
- Wind 10 mph

Tides in Nagatoyomachi
Today's high and low tides
- ▲ High tide 3:42 am 1.1 ft
- ▼ Low tide 11:14 am 0.3 ft
- ▲ Next high tide 6:40 pm 1.0 ft
- ▼ Low tide 10:44 pm 0.8 ft
↑ Rising The tide is rising. 3 h 27 min to high tide at 6:40 pm.
In Nagatoyomachi the astronomical tide is very small: about 0.8 ft between high and low tide. Here the sea level is moved mostly by wind and air pressure (storm surge), which can raise or lower it more than the tide itself.
2026 extremes: the highest tide of the year is on August 13 (1.3 ft) and the lowest, on March 22 (-0.4 ft).
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)

Where this tide comes from
Tides from the Suttsu station (JMA), 11 mi from Nagatoyomachi. Times and heights are its predictions.

The sea at Nagatoyomachi
Sea stateSea state: moderate
The waves you may find
- Most commonMost common2.8 ft
- Significant5.5 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 stay much the same all week. The biggest waves arrive on Thursday 29: 11 ft with a period of 8 s, from the west-northwest (rough).
Water temperature
Water temperature →The satellite measured 2.7 °F more 2 days ago than the model gives now: the water is probably warmer 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 56.1 °F by Wednesday 4.

Surf in Nagatoyomachi today
Surf today
Good- 2.9–4.5 ft surf at the shore, a good size with some punch
- 4.9 ft swell at 6 s from the west, short: weak, messy waves
- Almost no wind (4 mph): glassy water
- Light: First light 5:40 am · sunrise 6:09 am · sunset 4:37 pm · last light 5:06 pm
- Tide: We don’t have a reliable tide to show here.
- Water at 57.6 °F: a 4/3 fullsuit (booties if you run cold).
- Energy: 170 kJ · Medium power
Today’s surf at a glance
The best window, 7:00 am to 11:00 am, has a good size and glassy water, though with a short-period swell. 2:00 pm to 5:00 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 Nagatoyomachi today
Diving and snorkeling today
Likely visibility: poor- 4.5 ft swell at 6 s from the west: some surge on the bottom
- Light offshore wind (7 mph)
- 0.2 mph current toward the west, weak (model)
- Sun high: more light underwater
- Slack water today: none; the tide doesn't count here
- Likely visibility: poor. Swell (up to 9.4 ft at 8 s) and rain (0.45 in) over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 57.6 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 5:06 pm. Waning gibbous (88%), rising at 6:28 pm: a bright night.
Your diving day at a glance
The best window, 8:30 am to 11:30 am, combines light wind, weak current and the sun high, though with some swell. Also worth a look from 6:10 am to 7:30 am, with light wind and weak current, though with some swell.
In Nagatoyomachi the tide barely moves the water, so there's no slack to wait for: swell, wind and current are what count.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

The moon in Nagatoyomachi
Moon phase and position
Today the moon is 226,480 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 12:40–2:40 am Major · the moon passes overhead · high activity
- 1:12–3:12 pm Major · the moon passes underfoot · high activity
- 9:24–10:24 am Minor · moonset · medium activity
- 5:58–6:58 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 deep0.9 mi
- 164 ft deep1.5 mi
For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 0.25 mi): 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. Shore diving works here: 33 ft at 0.35 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).
Source: NOAA ETOPO 2022 (CC0), cells of about 0.3 mi; depth below mean sea level. For reference only: not for navigation or anchoring.
