Tides in Ko Olina
Today's high and low tides
- ▲ High tide 5:32 am 2.6 ft · coef. 83
- ▼ Low tide 1:04 pm 0.4 ft
- ▲ Next high tide 5:15 pm 0.8 ft · coef. 78
- ▼ Low tide 10:53 pm -0.1 ft
↑ Rising The tide is rising. 3 h 16 min to high tide at 5:15 pm.
Tide coefficient 83 for the 5:32 am high tide and 78 for the 5:15 pm high tide. Average coefficient. The water rises and falls 2.6 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 (2.8 ft) and the lowest, on May 17 (-0.5 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 8 to 10 (coefficient 95, 2.1 ft range). The smallest, on October 17 (coefficient 31, 1.4 ft).

The sea at Ko Olina
Sea stateSea state: moderate
The waves you may find
- Most commonMost common2.9 ft
- Significant5.8 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
The model doesn't separate offshore wind here: it's the same as on the coast.
Offshore wind. The coast faces southwest 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 Monday 2: 7.0 ft with a period of 12 s, from the north-northwest (moderate).
Water temperature

Surf in Ko Olina today
Surf today
Very good- 2.9–4.4 ft surf at the shore, a good size with some punch
- 3.7 ft swell at 11 s from the south, average
- Light offshore wind (11 mph): it holds up and grooms the waves
- First or last light of the day
- Falling tide (low tide at 1:04 pm)
- Light: First light 6:11 am · sunrise 6:34 am · sunset 5:59 pm · last light 6:21 pm
- Tide: high 5:32 am (2.6 ft), low 1:04 pm (0.4 ft), high 5:15 pm (0.8 ft) and low 10:53 pm (-0.1 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 79.5 °F–80.6 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 295 kJ · Medium power
Today’s surf at a glance
The best window, 6:11 am to 10:00 am, has a good size and light offshore wind.
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 Ko Olina today
Diving and snorkeling today
Likely visibility: poor- Some tidal current
- 3.7 ft swell at 11 s from the south: strong surge on the bottom
- Light offshore wind (11 mph)
- 0.8 mph current toward the west-northwest (model)
- Daylight
Not a day for shore diving: swell, wind, current or storms during the best window. If you go, go with a dive shop and only if they give the OK.
- Slack water today: high tide 5:32 am (5:10–5:50 am), low tide 1:04 pm (12:30–1:50 pm), high tide 5:15 pm (4:30–5:50 pm) and low tide 10:53 pm (10:20–11:20 pm)
- Likely visibility: poor. Swell (up to 3.9 ft at 12 s) and rain (3.33 in) over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 79.5–80.6 °F: a shorty or a rash guard.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:21 pm. Waning gibbous (90%), rising at 8:22 pm: a bright night.
Your diving day at a glance
The best window, 6:30 am to 7:10 am, lines up with light wind, though with tidal current, some swell and current. Also worth a look from 12:10 pm to 2:20 pm, with slack water at low tide and the sun high, though with some swell, moderate wind, current 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.
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 226,436 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 1:22–3:22 am Major · the moon passes overhead · high activity
- 1:54–3:54 pm Major · the moon passes underfoot · high activity
- 8:55–9:55 am Minor · moonset · medium activity
- 7:52–8:52 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

- 66 ft deep0.95 mi
- 164 ft deep1.5 mi
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. Shallow near shore: you only reach 33 ft at 0.85 mi. For dives deeper than 33 ft, go by boat.
