Port Glasgow tide times and boat scrubbing days

Port Glasgow is a UK Hydrographic Office tide station in Scotland at 55.933°, -4.683°. This page lists the next 7 days of official Admiralty high and low water predictions and flags the mornings when high water falls in the 06:30 to 09:00 scrubbing window. The interactive calendar extends this to a full month with harmonic predictions.

No high water falls between 06:30 and 09:00 in the next 7 days. The monthly calendar shows the next suitable scrubbing mornings.

Planning a scrub at Port Glasgow

  • Aim for a high water between 06:30 and 09:00 so the boat dries out through the morning and refloats on the afternoon flood.
  • Spring tides (around new and full moon) give a larger range and more working time on the grid.
  • Check the height of high water against the depth of your grid or posts; neap tides may not float a deep-keeled yacht on.
  • Predictions beyond 7 days are harmonic estimates. Confirm dates against official tide tables before committing a crane or grid booking.
