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
Dumbarton has no station of its own, so we use the tide at Millport (Environment Agency), 19 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.

The sea at Dumbarton
Sea state
The wave model doesn't reach Dumbarton: it's on inland water (an estuary, sound or sheltered bay) or far from the open sea. Wind is still available right here.
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 south and the wind blows straight in from the sea: more surf and backwash at the shore, and bait and boats drift toward land.

The moon in Dumbarton
Moon phase and position
Today the moon is 226,451 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 12:41–2:41 am Major · the moon passes overhead · high activity
- 1:12–3:12 pm Major · the moon passes underfoot · high activity
- 10:40–11:40 am Minor · moonset · medium activity
- 4:38–5:38 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.

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 0.4 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: the water doesn't reach 33 ft within 0.95 mi. For deeper dives, take a boat farther out.
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) 0.95 mi out. Where the bottom comes up to the surface there are shoals, rocks or an islet next to the profile.
