About tides at Avonmouth Portbury

Avonmouth Portbury sits on the South West coast and follows the standard semi-diurnal tidal pattern of the British Isles - two high tides and two low tides every 24 hours and 50 minutes, with each successive high arriving about 12 hours and 25 minutes after the last. Tide range at Avonmouth Portbury varies between spring tides (around new and full moon, when the Sun and Moon's gravity align for the biggest range) and neap tides (around the first and last quarter, when their forces partly cancel).

The live tide-height readings on this page come from the UK Environment Agency tide gauge network: actual sensor data, not an estimate. The 10-day forecast that follows is generated by Open-Meteo's ocean model and is calibrated each hour to the latest EA gauge reading at Avonmouth Portbury so the numbers match what you'd see on a printed tide table. Heights are quoted in metres above local chart datum, which is the convention used in UK Admiralty tide tables.

Whether you're sea fishing, surfing, kayaking, diving, kite-flying or just walking the dog along the beach, knowing the tide times for Avonmouth Portbury helps you plan around safe access, the run of the current and the productive feeding windows in either side of a tide change.

Anglers fishing the South West coast near Avonmouth Portbury typically cross-check the closest neighbouring gauges: Newport tide times (~12 miles along the coast), and Hinkley Point tide times (~26 miles along the coast) . Calibrated heights are pulled from the live EA gauge at 51.500°N 2.728°W.
