Westport Quay, Tuesday 20 October 2026. Heights in metres above OD Malin; "at the steps" is the depth at the foot of the swimming steps at the Point.
Tide	Time (IST)	Height	At the steps
High tide	02:06	+0.6 m	short of the steps
Low tide	08:21	−0.3 m	dry
High tide	14:11	+0.8 m	short of the steps
Low tide	21:09	−0.7 m	dry

Heights are metres above or below OD Malin (about mean sea level); add about 2.5 m for heights above chart datum. Times are Irish time. Worked out from the Marine Institute's predictions for Roonagh Pier, at the mouth of Clew Bay, shifted to the Quay: high tide about 20 minutes later, low tide about 35 minutes later, from the Admiralty's 1868 Sailing Directions and its modern predictions for Inishgort. No tide gauge has measured the Quay itself.

Depth of water at the foot of the steps through the day (midnight to midnight). Shaded: a metre or more, enough to swim. Grey bands: night and twilight. Dashed lines: wade (0.3 m), dip (0.7 m) and swim (1 m).

Wade 0.3 m+not today
Dip 0.7 m+not today
