About tides at Plymouth, Devon

Plymouth Sound is one of the great natural harbours of the English south-west, ringed by the city, the Hoe, and the breakwater that the Royal Navy built across the sound's mouth in the 1840s. The tide here runs the standard Channel signature: mean range about 4.2 metres, semidiurnal, two highs and two lows about twelve and a half hours apart. Spring tides push close to 5 metres, neaps drop near 2.4. The Tamar and the Plym both feed the Sound and both run entirely tidal in their lower reaches, draining into the harbour on each ebb and refilling over the four-hour flood. For anyone walking the Hoe waterfront, sailing out of Sutton Harbour, or kayaking up the Tamar past Saltash, the timing of the swing matters. The sea pool at Tinside, on the foot of the Hoe, fills from the tide and is best swum across the higher half of the cycle in summer. The rocky shelf at Wembury, south-east of Plymouth, opens up on the lowest spring tides for tide pooling. Predictions on this page come from Open-Meteo Marine — useful planning data, not navigation-grade. UK Hydrographic Office Admiralty TotalTide is the authoritative British tide product.

Tide questions about Plymouth, Devon

When is the next high tide at Plymouth?

The hero block shows the next high tide at Plymouth Sound in UK local time, height above MSL. The 7-day table covers daily highs and lows. High water at Devonport in the inner harbour lags the Sound by 10–20 minutes; the upper Tamar past Saltash lags further still.

What's the typical tide range at Plymouth?

Mean range at Plymouth Sound is about 4.2 metres. Spring tides — around new and full moons — push close to 5 metres, neaps drop near 2.4. The Channel south coast runs a typical macrotidal signal, with the western approaches seeing slightly smaller ranges than the funnel up at Bristol Channel.

When are the best low tides for tide pooling at Wembury?

Wembury, just south-east of Plymouth, has one of the better rocky-shelf intertidal zones on the south Devon coast. The pools open up most fully on the lowest spring tides of the month, which cluster around new and full moons. The 7-day table flags each day's predicted low; pair with sunrise from the sun/moon block above. The Marine Conservation Society runs guided rockpool sessions in summer.

Where do these tide predictions come from?

Open-Meteo Marine, a global ocean-grid model. The UK Hydrographic Office publishes the authoritative harmonic predictions via Admiralty TotalTide. Open-Meteo's data is useful for daily planning around Plymouth Sound and the Tamar, but is not a substitute for Admiralty data when piloting.

Is this safe to use for navigation?

No. For piloting in Plymouth Sound or the Tamar use UK Hydrographic Office Admiralty charts and tide tables, plus QHM Plymouth notices for the dockyard and the protected channels. Open-Meteo's gridded predictions are general-planning data, not a navigational source.
