Semidiurnal: two high and two low tides a day, of similar height.
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)

Where this tide comes from
Dunoon has no station of its own, so we use the tide at Millport (Environment Agency), 14 mi away. On the open coast the difference is usually a few minutes and inches; inside estuaries, rivers and enclosed bays it can be much larger.
Station data attribution: This uses Environment Agency tide gauge data from the real-time data API (Beta): Millport (E74024), https://environment.data.gov.uk/flood-monitoring/id/stations/E74024. Contains public sector information licensed under the Open Government Licence v3.0 (https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/).

Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.4 ft
- Significant0.8 ft
- Highest expectedHighest1.7 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 1.7 ft. Before heading out, expect waves of up to 1.7 ft.
Wind on the coast and offshore
Cross-shore wind. The coast faces east and the wind blows along the shore: drift and current run parallel to the beach.
Wave height, next 7 daysWaves, next 7 days
Waves ease over the next few days. The biggest waves arrive on Wednesday 28: 3.8 ft with a period of 4 s, from the south-southwest (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.

Your diving day at a glance
The best window, 12:20 pm to 1:30 pm, combines slack water at high tide, little swell, light wind, weak current and the sun high. Also worth a look from 10:00 am to 11:20 am, with little swell, light wind, weak current and the sun high, though with tidal 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 226,451 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 12:42–2:42 am Major · the moon passes overhead · high activity
- 1:14–3:14 pm Major · the moon passes underfoot · high activity
- 10:42–11:42 am Minor · moonset · medium activity
- 4:40–5:40 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
Deepens quicklyThe bottom deepens quickly: 33 ft of water 1,300 ft from shore. It reaches 164 ft at 0.45 mi.
From the shoreline (600 ft from Dunoon) out to sea, heading east.
How far from shore
- 16 ft deep1,150 ft
- 33 ft deep1,300 ft
- 66 ft deep0.3 mi
- 164 ft deep0.45 mi
For fishing, swimming and diving
- Shore fishing. 33 ft of water just 1,300 ft from shore: a good cast reaches deep water. Current and surf hit harder here.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. Shore diving works here: 33 ft at 1,300 ft and 66 ft at 0.3 mi from shore.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide. There is land ahead (an island, a headland or the far shore) 1.8 mi out.
