What is the Morston sailing window?

The Morston sailing window is the usable-light period around high water when harbour sailing at Morston Quay and Blakeney Harbour is typically planned — about ±2 hours around high 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.

How are Morston and Blakeney tide times calculated?

Tide times for Morston Quay and Blakeney Harbour are predicted from WorldTides at the Immingham reference station, then shifted by a local knowledge adjustment so they match the harbour clock used on this coast. Heights are on Chart Datum at Blakeney Bar. Times are in Europe/London (BST in summer, GMT in winter). Morston Quay uses the same times as Blakeney Harbour — no extra creek offset.

Are Morston and Blakeney tide times the same?

Morston Quay and Blakeney Harbour use the same locally adjusted tide times on this page, reflecting the harbour clock commonly used for planning around Blakeney Pit. Blakeney Quay may use a different local height or timing adjustment; select Blakeney Quay in the Morston app when planning specifically from the quay.

Can we put Morston tide times on our website?

Yes. Use Embed below the tide board on this page. Paste the snippet onto a harbour or village site and the Morston Today Tide Board stays current, with a quiet link back to Morston.

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.
This harbour: Burnham Overy is BHA Hull Albert Dock + 20 min (−8 min versus Blakeney) for high and low water. Heights −3.5 m onto the western creek chart datum. Window length uses the Blakeney-datum height so a spring is still a spring.
Local knowledge adjustment: Immingham times are shifted so they match the harbour clock used on this coast. Real tides still vary with wind and pressure.

About these Burnham Overy Staithe times

Burnham Overy Staithe sits on a drying creek behind Holkham. The Blakeney Harbour Association sets Overy high water at Hull Albert Dock + 20 minutes — eight minutes before the Blakeney clock. High and low water on this page both take that shift.

Heights are on the western creek datum, about 3.5 m below Blakeney Bar. A familiar 5.5 m spring at Morston reads around 2 m here. The tide has not vanished; the zero is different. The creek still goes away. On a neap you will wait, or walk.

This is dinghies, tenders, and the walk out over the marsh — not the Pit. Brancaster Staithe is the next creek west, about eight minutes earlier still. Do not run Overy times at Brancaster, or Blakeney times in the Overy creek.

Common questions

Does the creek dry?: Yes. Overy is a drying staithe. The window is when there is usable water around high water in daylight — not a promise you can leave a boat in at low water.
Why are the heights so much lower than Morston?: Western creek datum. Take about 3.5 m off a Blakeney Bar height. Judge the day by the range and by the creek in front of you, not by comparing the raw number to a Pit spring.
Is this the same as Brancaster Staithe?: No. Brancaster is about eight minutes earlier, same local datum. Close, not the same. Use the Brancaster page if you are on that staithe.
Is this for navigation?: No. The creek and the bar change. Planning only, and no guarantee of accuracy.
