Tides in Exmouth
Today's high and low tides
- ▲ High tide 12:06 am 8.5 ft · coef. 104
- ▼ Low tide 6:51 am 0.3 ft
- ▲ Next high tide 1:11 pm 6.7 ft · coef. 102
- ▼ Low tide 6:29 pm 2.5 ft
↑ Rising The tide is rising. 4 h 29 min to high tide at 1:11 pm.
Tide coefficient 104 for the 12:06 am high tide and 102 for the 1:11 pm high tide. Big spring tides. The water rises and falls 8.3 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 April 20 (9.5 ft) and the lowest, on October 28 (0.2 ft).
Mixed: two high and two low tides a day, but of quite different heights.
Heights above chart datum: the lowest astronomical tide (LAT), the zero of nautical charts in Europe. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. chart datum (LAT)
Tide coefficient and range in October
The biggest tides of the month came from October 27 to 29 (coefficient 104, 8.3 ft range). The smallest, on October 21 (coefficient 21, 1.9 ft).

The sea at Exmouth
Sea stateSea state: calm (rippled)
The waves you may find
- Most commonMost common0.2 ft
- Significant0.3 ft
- Highest expectedHighest0.7 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 0.7 ft. Before heading out, expect waves of up to 0.7 ft.
Wind on the coast and offshore
Offshore wind. The coast faces east 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 Tuesday 3: 2.4 ft with a period of 3 s, from the south (slight).
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.

Today’s surf at a glance
The best window, 5:18 am to 9:00 am, has light offshore wind, though with barely any waves.
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.

Your diving day at a glance
The best window, 6:00 am to 7:20 am, combines slack water at low tide, little swell and light wind, though with current. Also worth a look from 12:40 pm to 1:30 pm, with slack water at high tide, little swell, weak current and the sun high, though with moderate wind.
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 226,493 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 1:28–3:28 am Major · the moon passes overhead · high activity
- 2:01–4:01 pm Major · the moon passes underfoot · high activity
- 7:24–8:24 am Minor · moonset · medium activity
- 9:39–10:39 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.

- 33 ft deep1.2 mi
- 66 ft deep3 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. About 7.9 ft of water 330 ft out: long casts help, and so does a rising tide, which brings fish closer in.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. Shallow near shore: you only reach 33 ft at 1.2 mi. For dives deeper than 33 ft, 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).
