Tides in Koolauloa
Today's high and low tides
- ▲ High tide 4:12 am 2.6 ft · coef. 88
- ▼ Low tide 10:32 am 0.9 ft
- ▲ High tide 1:50 pm 1.4 ft · coef. 82
- ▼ Next low tide 8:52 pm -0.3 ft
↓ Falling The tide is falling. 2 h 12 min to low tide at 8:52 pm.
Tide coefficient 88 for the 4:12 am high tide and 82 for the 1:50 pm high tide. Average coefficient. The water rises and falls 2.9 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 (-0.6 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 25 to 26 (coefficient 104, 2.8 ft range). The smallest, from October 17 to 18 (coefficient 20, 1.5 ft).

Where this tide comes from
Tides from the Laie Bay station (NOAA), 3.1 mi from Koolauloa. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the Moku O Loe reference station with the official corrections.

The sea at Koolauloa
Sea stateSea state: moderate
The waves you may find
- Most commonMost common3.1 ft
- Significant6.1 ft
- Highest expectedHighest12 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 12 ft. Before heading out, expect waves of up to 12 ft.
Wind on the coast and offshore
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: 11 ft with a period of 11 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 is steady these days, with no sudden changes.

Surf in Koolauloa today
Surf today
Good- 3.3–5.2 ft surf at the shore, a good size with some punch
- 3.9 ft swell at 8 s from the north-northeast, a bit short
- Almost no wind (2 mph): glassy water
- Falling tide (low tide at 8:52 pm)
- Light: First light 6:10 am · sunrise 6:33 am · sunset 5:57 pm · last light 6:20 pm
- Tide: high 4:12 am (2.6 ft), low 10:32 am (0.9 ft), high 1:50 pm (1.4 ft) and low 8:52 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 79.2 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 205 kJ · Medium power
Today’s surf at a glance
The best window, 2:00 pm to 6:00 pm, has a good size and glassy water.
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 Koolauloa today
Diving and snorkeling today
Likely visibility: poor- 3.9 ft swell at 8 s from the north-northeast: some surge on the bottom
- Almost no wind
- 0.6 mph current toward the northwest (model)
- Sun high: more light underwater
- Slack water today: high tide 4:12 am (3:50–4:30 am), low tide 10:32 am (10:00–10:50 am), high tide 1:50 pm (1:30–2:30 pm) and low tide 8:52 pm (8:30–9:10 pm)
- Likely visibility: poor. Swell (up to 5.1 ft at 12 s) and rain (2.99 in) over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 79.2 °F: a shorty or a rash guard.
- 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, 12:50 pm to 1:30 pm, combines light wind and the sun high, though with some swell and current. Also worth a look from 9:40 am to 11:10 am, with slack water at low tide, light wind and the sun high, though with some swell 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.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

The moon in Koolauloa
Moon phase and position
Today the moon is 226,436 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 1:21–3:21 am Major · the moon passes overhead · high activity
- 1:53–3:53 pm Major · the moon passes underfoot · high activity
- 8:55–9:55 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.

Water depth

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. Shallow near shore: you only reach 33 ft at 0.75 mi. For dives deeper than 33 ft, go by boat.
