How these tide times are calculated

Data source: WorldTides harmonic predictions for the North Sea.
Reference station: Immingham (53.6183°N, 0.1817°W).
Prediction point: Morston Quay, Blakeney Harbour — the same clock as Blakeney, with no extra creek offset.
Datum: Chart Datum (CD) at Blakeney Bar. Heights are 1.4 m below the raw Immingham feed so a typical high water reads around 5 m.
Timezone: Europe/London — BST in summer, GMT in winter.
Local knowledge adjustment: Immingham times are shifted by a local knowledge adjustment so they match the harbour clock used on this coast. Real tides still vary with wind and pressure.

Common questions

Are Morston and Blakeney tide times the same?: Yes on this page — Morston Quay and Blakeney Harbour use the same locally adjusted times, the harbour clock commonly used for planning around Blakeney Pit. Blakeney Quay may differ; choose it in the Morston app when planning from the quay.
What is the sailing window?: Roughly ±2 hours around high water in usable daylight — when many Morston and Blakeney sailors plan to get on and off the water. On tides of 5.5 m and above, the window stays open an extra half hour after high water. If the tide is still in after sunset, the window runs until twilight (when usable light for navigating effectively stops).
Where does the weather come from?: Met Office Weather DataHub for weather and wind, and Open-Meteo for marine wave height. Tide times are WorldTides at Immingham, then locally adjusted as above.
Is this for navigation?: No. Use it for planning only. There is no guarantee of accuracy — check conditions yourself and never rely on an app alone on the water.
