About tides at Harwich

Harwich sits on the East of England 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 Harwich 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 Harwich 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 Harwich 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 East of England coast near Harwich typically cross-check the closest neighbouring gauges: Felixstowe tide times (~3 miles along the coast), and Southend tide times (~38 miles along the coast) . Calibrated heights are pulled from the live EA gauge at 51.948°N 1.292°E.
