Fidra tide times and boat scrubbing days
Fidra is a UK Hydrographic Office tide station in Scotland at 56.067°, -2.783°. 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.
One morning in the next 7 days has a high water between 06:30 and 09:00, the ideal window to put a boat on the scrubbing grid or posts: Thu 17 Sept.

Planning a scrub at Fidra
- 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.
