Coastal Ocean Temperatures off WA: CSIRO Marine Research - Regional Oceanography

Changes in ocean temperature are of immense importance for global climate studies, marine ecology and fish recruitment, as well as being of interest to recreational swimmers. Because of the Leeuwin Current, water temperatures off Western Australia are some 4°C warmer than those at corresponding latitudes off the west coasts of southern Africa and South America. Water temperature measurements along the Western Australian coast are relatively sparse, although some intensive studies have been undertaken near cities and regional centres, as well as at selected sites important for fisheries.

Monthly temperature statistics have been compiled for a number of sites along the west coast of Australia, using a variety of data sources. To view monthly average temperature and minimum and maximum recorded at any site, click on the appropriate places on the map via the URL.
