The water rises and falls 6.3 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 September 12 (6.9 ft) and the lowest, on December 25 (-0.8 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

Sea stateSea state: moderate
The waves you may find
- Most commonMost common3.6 ft
- Significant7.2 ft
- Highest expectedHighest15 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 15 ft. Before heading out, expect waves of up to 15 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Offshore wind. The coast faces west 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 build over the next few days. The biggest waves arrive on Wednesday 4: 16 ft with a period of 11 s, from the east-southeast (very 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 81.2 °F by Wednesday 4.

Surf in Zaisho today
Surf today
Poor- 2.2–3.3 ft surf at the shore, a fun size for most surfers
- 4.3 ft swell at 7 s from the north-northeast, short: weak, messy waves; it hits this coast at an angle
- Fresh offshore wind (24 mph)
- Rising tide (high tide at 8:42 am)
- Light: First light 5:58 am · sunrise 6:21 am · sunset 5:36 pm · last light 6:00 pm
- Tide: low 2:06 am (0.1 ft), high 8:42 am (6.0 ft), low 2:14 pm (2.7 ft) and high 8:00 pm (6.3 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 82.0 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 268 kJ · Medium power
Today’s surf at a glance
The best window, 6:00 am to 10:00 am, has a good size, though with a short-period swell. 3:00 pm to 4:00 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 Zaisho today
Diving and snorkeling today
Likely visibility: poor- Slack water around low tide (2:14 pm): little current from 1:50 pm to 2:40 pm
- 4.2 ft swell at 6 s from the north-northeast: some surge on the bottom
- Fresh offshore wind (19 mph): it pushes surface swimmers away from shore
- 0.9 mph current toward the west (model)
- Sun high: more light underwater
- Slack water today: low tide 2:06 am (1:50–2:21 am), high tide 8:42 am (8:20–9:10 am), low tide 2:14 pm (1:50–2:40 pm) and high tide 8:00 pm (7:40–8:20 pm)
- Likely visibility: poor. Swell (up to 6.5 ft at 6 s) and wind over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 82.0 °F: a shorty or a rash guard.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:00 pm. Waning gibbous (88%), rising at 8:05 pm: a bright night.
Your diving day at a glance
The best window, 1:30 pm to 3:00 pm, combines slack water at low tide and the sun high, though with some swell, fresh wind and current. Also worth a look from 8:10 am to 9:30 am, with slack water at high tide, though with waves, fresh wind 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.

Moon phase and position
Today the moon is 226,480 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 1:17–3:17 am Major · the moon passes overhead · high activity
- 1:49–3:49 pm Major · the moon passes underfoot · high activity
- 9:03–10:03 am Minor · moonset · medium activity
- 7:35–8:35 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. Deep water close in: about 193 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. Shore diving works here: 33 ft at 40 ft and 66 ft at 80 ft 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.
