Lowestoft tide gauge site

The disused tide gauge building can be seen in the centre of the picture mounted above the two stilling wells. The present building is situated to the right of the Harbour Master's Office with the pressure points located on the quay wall approx 20m to the right of the old tide gauge building. Wind speed and direction instruments are mounted on the pole attached to the right hand side wall of the Harbour Master's Office.

Tide gauge location

The tide gauge equipment housed in the Glasdon building consists of a pneumatic bubbler system with two full tide and mid-tide pressure points mounted on steelwork attached to the quay wall. All three pressure lines, wind speed and wind direction are monitored by the POL data logger. A pressure signal is also supplied to an Ott pneumatic gauge for use by the Harbour.

The tide gauge is levelled to the tidal gauge bench mark support by Ordnance Survey auxiliary marks.
