2026 extremes: the highest tide of the year is on August 14 (7.7 ft) and the lowest, on December 25 (-1.0 ft).
Mixed: two high and two low tides a day, but of quite different heights.
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

The sea at Naminoue Beach
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.8 ft
- Significant3.5 ft
- Highest expectedHighest7.3 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 7.3 ft. Before heading out, expect waves of up to 7.3 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 Wednesday 4: 7.7 ft with a period of 10 s, from the east-northeast (moderate).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water is steady these days, with no sudden changes.

Surf in Naminoue Beach today
Surf today
Fair- 2.0–3.0 ft surf at the shore, a fun size for most surfers
- 2.4 ft swell at 6 s from the north, short: weak, messy waves
- Light offshore wind (10 mph): it holds up and grooms the waves
- First or last light of the day
- Rising tide (high tide at 9:16 am)
- Light: First light 6:12 am · sunrise 6:36 am · sunset 5:50 pm · last light 6:13 pm
- Tide: low 2:44 am (-0.0 ft), high 9:16 am (6.4 ft), low 2:48 pm (2.9 ft) and high 8:37 pm (6.9 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 80.8 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 46 kJ · Low power
Today’s surf at a glance
The best window, 6:12 am to 10:00 am, has a good size and light offshore wind, though with a short-period swell. 3:00 pm to 6:00 pm can also work, with 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 Naminoue Beach today
Diving and snorkeling today
Likely visibility: good- Slack water around low tide (2:48 pm): little current from 2:20 pm to 3:20 pm

- Likely visibility: good. Swell (up to 3.5 ft at 7 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 80.8 °F: a shorty or a rash guard.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:13 pm. Waning gibbous (88%), rising at 8:18 pm: a bright night.
Your diving day at a glance
The best window, 1:30 pm to 3:40 pm, combines slack water at low tide, light wind and the sun high, though with current. Also worth a look from 8:30 am to 10:20 am, with slack water at high tide, light wind and the sun high, though with 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- 1:32–3:32 am Major · the moon passes overhead · high activity
- 2:04–4:04 pm Major · the moon passes underfoot · high activity
- 9:19–10:19 am Minor · moonset · medium activity
- 7:48–8:48 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. Shallow, gradual bottom (16 ft at 0.3 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. 33 ft deep 0.35 mi from shore; 66 ft is far out (1.6 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).
