Every predicted high and low for the next week, with the daily tidal coefficient (0–120; higher = bigger swing, > 95 means stronger currents).
The three closest curated TideTurtle locations to Plymouth, Devon, measured by great-circle distance.
Solunar tradition: major periods are the ≈3h windows around moon transit and opposition; minor are ≈2h around moonrise and moonset. Pair with the local tide stage and wind for the best read.
Next spring tide on Wed 17 Jun (range 4.8m / 15.9ft). Last neap on Thu 11 Jun.
Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.
A short guide to the coastline at Plymouth, Devon — geography, sea state, and what the tide is actually doing under your feet.
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. 2 metres, semidiurnal, two highs and two lows about twelve and a half hours apart. 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.
Quick answers to the most common questions about tide times, range, and water access at Plymouth, Devon.
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.
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.
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.
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.
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.
