Tides in Marine Corps Base Hawaii - MCBH
Today's high and low tides
- ▲ High tide 4:33 am 2.6 ft · coef. 87
- ▼ Low tide 11:04 am 1.2 ft
- ▲ Next high tide 2:11 pm 1.4 ft · coef. 82
- ▼ Low tide 9:24 pm -0.3 ft
↑ Rising The tide is rising. 2 h 12 min to high tide at 2:11 pm.
Tide coefficient 87 for the 4:33 am high tide and 82 for the 2:11 pm high tide. Average coefficient. The water rises and falls 3.0 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 13 (2.9 ft) and the lowest, on May 17 (-0.8 ft).
Mixed: two high and two low tides a day, but of quite different heights.
Heights above mean lower low water (MLLW), the zero of US 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. MLLW
Tide coefficient and range in October
The biggest tides of the month came from October 24 to 26 (coefficient 104, 2.9 ft range). The smallest, from October 17 to 18 (coefficient 20, 1.4 ft).

Where this tide comes from
Tides from the Moku O Loe station (NOAA), 2.7 mi from Marine Corps Base Hawaii - MCBH. Times and heights are its predictions.

The sea at Marine Corps Base Hawaii - MCBH
Sea stateSea state: moderate
The waves you may find
- Most commonMost common2.3 ft
- Significant4.7 ft
- Highest expectedHighest9.4 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 9.4 ft. Before heading out, expect waves of up to 9.4 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Onshore wind. The coast faces northeast and the wind blows straight in from the sea: more surf and backwash at the shore, and bait and boats drift toward land.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Monday 2: 8.9 ft with a period of 9 s, from the north (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 77.8 °F by Tuesday 3.
Water about normal for late October.

Surf in Marine Corps Base Hawaii - MCBH today
Surf today
Fair- 2.7–4.2 ft surf at the shore, a good size with some punch
- 3.5 ft swell at 8 s from the north-northeast, a bit short
- Moderate onshore wind (13 mph): a bit of chop
- Falling tide (low tide at 9:24 pm)
- Light: First light 6:10 am · sunrise 6:32 am · sunset 5:57 pm · last light 6:20 pm
- Tide: high 4:33 am (2.6 ft), low 11:04 am (1.2 ft), high 2:11 pm (1.4 ft) and low 9:24 pm (-0.3 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 78.6 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 146 kJ · Medium power
Today’s surf at a glance
The best window, 4:00 pm to 6:00 pm, has a good size, though with onshore wind. 7:00 am to 9:00 am can also work, with a good size, 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 Marine Corps Base Hawaii - MCBH today
Diving and snorkeling today
Likely visibility: poor- Slack water around high tide (2:11 pm): little current from 12:50 pm to 2:50 pm

- Likely visibility: poor. Swell (up to 4.6 ft at 8 s) and rain (3.59 in) over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 78.6 °F: a 3 mm wetsuit.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:20 pm. Waning gibbous (90%), rising at 8:20 pm: a bright night.
Your diving day at a glance
The best window, 12:30 pm to 3:20 pm, combines slack water at high tide, weak current and the sun high, though with some swell, moderate wind and heavy rain. Also worth a look from 9:40 am to 10:30 am, with slack water at low tide, weak current and the sun high, though with some swell, moderate wind and heavy rain.
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.

The moon in Marine Corps Base Hawaii - MCBH
Moon phase and position
Today the moon is 226,436 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 1:20–3:20 am Major · the moon passes overhead · high activity
- 1:52–3:52 pm Major · the moon passes underfoot · high activity
- 8:53–9:53 am Minor · moonset · medium activity
- 7:50–8:50 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.
