GLOSS Station Handbook – Port Louis Harbour

The GLOSS Station Handbook is currently being re-designed and upgraded.

Until a new version is available, the tide gauge station list below from the last version of the Handbook provides links to further details about each tide gauge in the GLOSS Core Network. Click column headings to sort the station list table. Click the GLOSS number buttons to view the station information.

Additional information
Other relevant information	Munro tide gauge in a stone building, corner of Quay D, dismantled in early 1970s. Zero of recorder corresponds to a marked level situated seven feet below the level of the Quay. This datum point denotes the level of the mean low water at spring tides and was selected in 1929 after taking the average of the low water spring tide levels over a 48 month period. Local levellings are undertaken at intervals of 6 months.
Nearest Met. station	Meteorological station, Vacoas
